Hey everyone,
So this is just a build i did to showcase how easy and simple this challenge could be.
This was done with the simple Reverse Dogtape mod and some 3D fixtures, nothing fancy, but the result is very good.
And no this car won’t be judged or be in the running of the challenge lol.
-
Also do not just copy this build exactly, put your own personal style & spin on things
-
You can do any style you want, this was just built by using the inspo pics on the forum as inspiration
Have Fun!

Since 1980, Satin Panthers have tried our best to stand out with unconventional designs, and now we’ve used that knowledge and made the ultimate RoboRacer of Tomorrow for the racing fans of today.
Chassis and Bodywork
Most roboracers are open, low to the ground, and somewhat unsightly, all for the benefit of aerodynamics. The SP9-R is low, but unlike other roboracers, it has a more closed off design. The body shell is based off of the mold for the legendary Satin Panthers SP4, the 6 time Le Mans winner. From there, we cut down the cabin’s cross section and replaced the carbon fibre monocoque with a plate chassis designed around the massive 16ft long titanium diffuser. Affixed to the diffuser are the suspension crossmembers, which hold the carbon fibre leaf springs that act as wishbones and springs. The front suspension crossmember holds the differential and the steering motor while the rear is empty, due to the unique design of the powertrain.
Powertrain and Running Gear
HDi (Hewlett Diesel Industries) has been our engine supplier since 1990, and for this championship, they’ve produced a very special diesel. 1,900hp comes out of the crankshaft of this 7.6L monster V10 thanks to two massive turbochargers and advancements in compression ignition engines. This is paired with a 7 speed sequential mated directly to the differential to drive the front wheels. The rear wheels are driven by the latest in hub motor technology provided by the Shibuya Motor Company, giving a total of another 1,900hp. The braking system is hydraulic up front with carbon ceramic discs, while the rear is entirely regenerative with active water cooling (achieved by using the rotor of the motor as a water pump which pushes coolant through a pair of radiators) to prevent any untimely failures. All this engine would be a waste without a way to drive it, so we made it drive
Fuel
The SP9-R is a diesel electric hybrid, so it needs both a fuel source and an energy store. The fuel tank is a sizable 112L of volume, which makes it very efficient for races like Le Mans or the Daytona 500. The batteries are not as large at 12.75KWh, but for silver-cadmium batteries, they’re not bad at all. The batteries are charged through 3 methods: DC Fast Charging, regenerative braking, or Cadmium Telluride Photovoltaic cells. DC Fast Charging is primarily used for endurance races, regen is king in night races, and CaTd cells are great for the average race.
The AI
We are no AI masters, make no mistake. So, when we fired up CaliCode v.75.3, we didn’t expect it to be easy, except it was. In less than a week, not only did the test car we have move, but
Sensors
During the development of our sensors, we ended up having a minor stroke of luck and managed to create contextually aware sensors, which would help with complex situations.
For our first endeavour into AI racing we gave all we could, and it looks like we have a solid chance at success. May the best car win.

EURDC MicroRacer
Presented by the European Union Robotics Development Cooperative (EURDC), the MicroRacer is an implementation of new development processes in creating smaller scale machines for inner-city competition.
Technology & Construction
The MicroRacer makes use of a number of advanced components to provide racing similar to those driven by people. Making use of proximity sensors placed on all corners, as well as InfraRed and Direct Feed cameras placed on the front and rear of the vehicle, this allows for the MicroRacers to figure out their positions in real time.
The Lighting systems on the front, sides, and rear of the MicroRacer are intended to be used to display team affiliations, safety messaging, and performance information in a quick, easy to understand method which does not rely on written text.
The MicroRacer is also equipped with the “TeamMesh” system, allowing for teams to field four cars to increase accuracy of position, and allow for increased tactical advantages.
The MicroRacer uses carbon-composite components throughout leading to a weight below 500kg, with many components internally created with Carbon-Kevlar to help reduce weight further.
Aerodynamically, the MicroRacer makes use of only three main sources of generating downforce due to the small size, being the high-placed rear wing, the small front wing elements connecting the outboard covers and the main chassis, and a pair of extraction fans on the rear to generate a small amount of suction force through the underbody.
Pushrod Suspension is mated to Carbon-Ceramic brakes alongside all around 225/30R14 wheels wrapped in Slick rubber tyres to allow for maximum mechanical grip.
Power
Compared to a 2009 Sinistra Traville SE-3900 PHEV
The MicroRacer is small, featuring a wheelbase of only 1.4m, as well as full light-weight composite construction. This leads to a requirement for relatively little power for relatively quick acceleration. The MicroRacer constitutes a requirement for less power and less drawn charge compared to its compatriots for similar performance. Using only 350HP equivalent, the MicroRacer accelerates to 60mph in 2.0 seconds and reaches a limited top speed of 175mph due to expectations of race track.
Providing the power to the motors are a number of high-energy density thin-film solid-state batteries dispersed through the chassis to improve weight distribution.
Ideology
The ideas behind the MicroRacer are to bring the excitement of motorsport to the most people possible. Targeting races within city centres, the small scale of the MicroRacer means more machines can be on smaller tracks, in better to reach and view locations. This allows any person to come and watch, while opening the door to increased accessibility and ease of access. Placing our events in city centres means transport options already exist, and places the event within walking distance of numerous transport links.
MicroRacer is a trademark of EURDC, EURDC subsidiaries and partners.

The Ultimate PowerMac G5… perfect for all AI racing needs (as long as you rip everything out of it and replace it all)
tl;dr -- SRT Tomahawk-meets-Red Bull X1-meets-Racing Miku
2060 Cornell Project OCEANS
Organic Circuitry, Emotive And Neuroidentical Systems
On the 130th anniversary year of the founding of the Cornell brand, we’ve come to present a special machine to the Roboracers community…
Propulsion Systems
- The main power is driven by a six-rotor wankel utilizing an AMC-SC1 billet magnesium alloy block, titanium-copper rotors and titanium-carbide apex seals, fueled with plant-based E100. It’s very reliable, lightweight and power-dense, producing 1300 bhp at 16500 RPM and 850 lb-ft of torque at 5600 RPM, while directing it entirely to the 345/35R21 rear wheels via a seven-speed sequential transmission.
- All four wheels are assisted with permanent-magnet electric motors embedded in each wheel hub, making a theoretical, combined maximum 2500 bhp and 3125 lb-ft of torque, used exclusively at speeds under 140 mph to assist in mid-low speed acceleration.
- The 305/40R20 front wheels are assisted further with a pneumatic drive system, also utilized in its wake modification systems, providing an extra 475 bhp to the front wheels between the speeds of 140 and 200 mph.
Aerodynamics and Drivetrain
- Fan car system utilizing twin intake fans extracting air out from underneath the car and exhaust fans pushing it out in front of the rear wheels, mixed with proprietary ground-effects bodywork and active aerodynamics to maximize downforce in adverse weather conditions. This system is dynamically modulated with the wake modification system described below to reduce drag on straightaways and increase downforce on corners, gluing the sub-2000 lb. chassis to the floor. Electronically-actuated active front and rear pullrod suspension ties it all together.
- Wake modification systems working in conjunction with the fan car technology, assisting in diffuser air extraction, altering slipstream characteristics and enhancing downforce at a minimal addition to drag.
- Non-pneumatic, self-regenerating tires embedded with induction coils to charge batteries via driving (reserved exclusively for pit lane use).
Sustainability
- Created with environmentally-friendly materials like titanium-copper & aluminum-bronze alloys, recycled carbon fiber, bio-plastics and plant-based rubber.
- Utilizing modified Midlands Future Racing-developed fungal biofilm technology in electric & pneumatic filament systems (dubbed fWire & fPipe, respectively) to dynamically alter response time alongside pressure/voltage & current, reducing workload on electronic & pneumatic systems, and perform self-healing functions in dire situations.
Emotion Engine AI
Emotion Engine ID 4044312.K - "Kaybee"
- Emotion Engine™ Autonomous, Cerebro- and Neuro-Identical Intelligence (EE ACNII), developed by Inoue Applied Robotics, is a very personable, emotive and human-reactive machine learning software that aims to fill the gap between the consistency and precision of AI powered machines with the personality and empathy of human drivers.
- EE ACNII software is transmitted directly from the android housing to the car for race events, and back to the android between races for interviews, fan interactions, collaboration with engineers and aerodynamicists, and many more applications.
- Onboard software is connected directly to three LIDAR arrays, stereoscopic video feed, ultrasonic range detector, carrier-phase enhanced GPS systems and offloaded processing with Midlands Future Racing-derived Crew Chief Computing™ systems.

Someone else going for the strategy of sentient robocar that’s also a robot/android? Impressive, I wish you the best in this
2060 Fujimi Alpha X-01
For the 2060 Roborace season, Fujimi’s Advanced Motorsport Division presents their first entry into the series - the Alpha X-01. Among its highlights there is a bespoke carbon fibre monocoque, an E-Fuel-drinking quad-turbo V12 with 1200 bhp as well as a supercapacitor hybrid system, which uses a front-mounted motor-generator unit, capable of producing 300 kW on both acceleration and regeneration. The supercapacitor array allows for a quick discharge of power, giving the motor a temporary boost to 400 kW for use on straightaways. As far as autonomous capability goes, it uses a set of sensors and cameras, GPS and GLONASS positioning systems, all feeding a Fujimi Electron Industries Deep-Learning core.

DELPHINIDA PRESENTS
in collaboration with
DIMOLTO TECHNOLOGIES
The Strength
CARBON FIBER NANOTUBE CONSTRUCTION
The AM-X is mainly made of sturdy, but light carbon fiber nanotubes, combined with regular carbon fiber, silver, plastic, and other components. It’s equipped with drive-by-wire technology, minimizing mechanical linkages and saving weight. The body, along with the chassis, motors, batteries, wheels, suspensions, computer, and other amenities add up to a kerb weight of 1010 kilograms.
PASSIVE AERO
Aside from the obvious diffuser, splitters, and fin at the back end of the car, the AM-X has a large panel surrounding the main body. The panel serves as weather and impact protection for the wheels, suspensions, and main body, as well as containing several useful sensors. It’s also shaped to generate downforce as well as direct cool air right to the wheels and vents without trapping too much and creating drag. As seen here, it also serves as a good placement for sponsors.
ELECTRIC MOTORS
The AM-X is powered with 4 electric motors (25 kg motors on the front, 55 kg motors on the rear, 160 kg total), one for each wheel. They produce a combined output of 2000 hp (1500 kW) of power and 2200 Nm of torque, with 600 hp and 660 Nm on the front end and 1400 hp and 1540 Nm on the rear.
COMPACT BATTERIES
In an attempt to save weight, the AM-X uses a highly compacted 500 kWh lithium iron phosphate “blade battery” known for its efficiency and safety for a long time, placed as low as possible to lower its center of gravity. The battery’s total weight is around 200 kg.
About the “blade battery”: Introduced in the early 2020s by a manufacturer in China, the “blade battery” is a lithium iron phosphate, single-cell battery with a design that allows it to be placed in an array and put into a battery pack, like a blade. It was claimed to be safer, more powerful, and lasts longer than the then-conventional ternary lithium or lithium iron phosphate batteries. With how various electric vehicle manufacturers have adopted its use in the following years, Delphinida’s decision to use this battery type was because of an already reliable access to the battery’s replacement and/or reparation, if needed.
CARBON CERAMIC BRAKES WITH KERS
The AM-X has carbon ceramic brakes (420 mm/3-piston front, 400 mm/2-piston rear) on each wheel (P355/25R23 front, P365/25R23 rear) directly cooled by air flowing between the wheels, the main body, and the surrounding body panel. With it also comes a KERS system with a small flywheel connected to each motor (80 kg in total), storing energy from the motors under braking in a battery to release later on as a temporary boost. Each KERS unit can put out up to 120 hp (90 kW) of boost, with a total up to 480 hp (358 kW).
AIR AND LIQUID COOLING
The AM-X utilizes a combination of liquid coolant, circulated in its main body like blood in a human’s (coolant and circulation system weighs around 30 kg), and cool air coming into its side intakes to cool its computer, battery, motor, brakes, and more. Air coming in the intakes is also used to cool the liquid coolant, increasing its reusability.
The Smarts
CENTRAL PROCESSING UNIT
Located just beneath the antenna, the AM-X’s CPU boasts an octa-core processor, a large memory connected to DiMolto Technologies’ servers, and accelerators to help it in effectively multitasking and decision making. It’s completely made in-house specific for the AM-X, however, making reparations quite a hassle.
FULL 360° VISIBILITY
The AM-X has a full 360° sensor and camera coverage to precisely gather information about its and its opponents’ position, speed, and movements, even at night. This includes radars mounted front and rear, LIDARs on each corner, additional proximity sensors on the sides (marked with white squares) for good measure, and cameras with infrared mounted on each side as well as on top.
SELF-ASSESSMENT
The AM-X is equipped with an information system that gathers data about its tire pressure and tread status, structural integrity, battery level, motor heat, and more. This data is then used to create a risk assessment and success probabilities for determining next actions.
ENVIRONMENT ASSESSMENT
Aside from itself and its surroundings, the AM-X can detect and assess the weather, wind speed and direction, air and track humidity. A top-mounted pitot tube, humidity sensors within the splitters, and connection to the local weather forecast provider enables access to data needed to predict the AM-X’s optimum movements in rain, strong winds, and other conditions.
ACTIVE AERO PIECES
In addition to the huge fin and surrounding body panel, the AM-X has adaptable aero pieces mounted around the same level with the wheels (marked with yellow accent on the edges, whole system weighs 20 kg), which aids in braking and turning when needed and can straighten out to reduce drag.
ACTIVE PUSHROD SUSPENSIONS
Demonstrated in the early '80s to '90s by several Formula 1 teams, the active suspension maintained the vehicle’s grip and stability at its best. This was achieved by adjusting the stiffness and ride height automatically for every wheel with hydraulic actuators, to adapt to every corner, every bump, and even correcting the occurrences of oversteer or understeer.
Delphinida decided that reinstating this technology would give the AM-X an edge in the competition, especially combined with its extensive sensor coverage, increasing detection of terrain changes to adapt to. While changes in the handling were an issue for drivers in the past, they’re confident that the AM-X’s driver, an AI, won’t be too bothered by it. It can even be argued that the driver himself is naturally adjusting these suspensions, like its own appendages. A pushrod geometry was chosen for the AM-X to maintain aerodynamics, despite being less precise than the current state-of-the-art fully articulating hydraulic multi-link configuration. The active suspensions weigh about 30 kg in total.
COMMUNICATION SYSTEMS
The AM-X communicates with the team and the outside world with its low-latency GNSS antennae, sending status of itself, its surroundings, and courses of actions it plans to take, as well as distress signals if needed. The antennae also enables the AM-X to access data to its positioning, local time, and movements its sensors and cameras are obscured from.
The Soul
BABYFACE™
Babyface™ is the AM-X’s pilot, courtesy of DiMolto Technologies. A combination of a chatbot’s and a maid robot’s software, he was created as a “learning intelligence,” being able to learn from feedback via text inputs, observation of learning materials (including the world around him), as well as trial and error. Basically, a highly intelligent child.
From previous tests, the team in Delphinida and DiMolto Technologies have tirelessly bonded and trained with Babyface™ not only to train him into a proficient track runner, but also to establish a strong bond and understanding, as well as clear barriers between him and the rest of the team. Babyface™ has shown his capabilities of finding and taking chances, complex maneuvers, and even copy movements from his competitors.
However, occasionally, it has shown what can be described as “rebellious attitude,” exhibiting dirty driving as well as ignoring direct intervention via text inputs or direct control assumptions. The team usually just laughs it off, though, as it always leads to position gains. After all, Babyface™ is their child. What could possibly go wrong?
The Suppliers
DELPHINIDA
Established 2001, Delphinida is a luxury-exotic division of the Japanese company Kotatsu. By 2005, they also started working on experimental vehicles that occasionally, if successful, were later released under its own or the Kotatsu brand. The AM-X is not its first performance-focused experiments, but considering the lack of human drivers (and therefore safety concerns), this might be its craziest yet.
DIMOLTO TECHNOLOGIES
Established 2001, DiMolto Technologies started out with making electronic appliances. Over time, they started to delve into the AI market, creating programs such as chatbot, home assistant, and even helping out on national programs of third-world countries, such as electronic medical records and national censuses. The idea of Babyface™ came from an intern after watching an old anime that aired in 2019, and is now assigned to pilot the Delphinida AM-X in the upcoming Vision 2060. If the project is a success, Babyface™ may be integrated into mass products such as dolls, maid bots, and even military androids.

Y’all can fix these in your existing posts, no worries.
Note to @ArizonaCaseo regarding Hironium alloy specifically - not sure if that’ll work. It is also missing some basic spec sheet stuff such as curb weight and tire dimensions. Also what is a “dual transverse leaf sprung independent suspension” and can you explain how the rear motors are “actively cooled”? (and basic specsheet please) Otherwise the sensor stuff looks good.
Note to @Fayeding_Spray the microracer is missing a lot of spec sheets, we don’t know what it is powered by, what type of battery, what it’s made out of, suspension or aerodynamic details, and tire dimensions. (Among other things)
Note to @kaybee thank you very much for providing article links, we love it. Can you explain a little bit on the fungal biofilm tech? (why it’s needed / why reduce workload)
Note to @the-chowi can we have weights and tire dimensions too, otherwise it’s pretty good.
Note to @azkaalfafa what is a “blade” battery in this case? May also want to go more in-depth about the adaptive suspension and the KERS units - are they separate flywheels or are part of the eMotors… or use the motors to turn it into electric energy back into the batteries? Also, curb weight, torque and tire/brake dimensions would be nice. Otherwise it’s good.
A good example of showing specs for each component would be Veiona, each component of the car receiving its own detailed description and also giving the exact engineering numbers.
Anyways that’s it from me, thanks guys!

Can I use depleted Californium or is that too far of a stretch? If so, I’ll probably just use titanium or something else
Hmm are there any articles for this? Because as far as I know californium isn’t found in nature and its main use is to be made in laboratories as a neutron source (for other things). As for using depleted californium in an alloy, it might work but I’m not knowledgeable enough about it specifically.
Materials engineering is extremely hard so I’d advise against this route. For more reading you can do:
The closest I can find for “Hironium” is:
But even then, why do you want an extremely dense material for building your car? It might get really heavy, and although its dense, depleted uranium or its alloys aren’t well-known for its use in construction or strength, only density.
IMO materials engineering is extremely difficult (and inventing new ones moreso) but most of the advances recently are in composites - alloys are fundamentally different and I don’t see any truly revolutionary alloy coming in the next 50 years probably.
Alright, I guess Titanium is all I can use, it’s a shame since Californium is such a cool name but what can I do besides obey the laws of reality
