Robo Race Organization Introduction
- Robo Race: organization specializing in autonomous racing
- Develops own autonomous race cars
- Runs competition for teams to develop autonomous driving software
- Goal: further autonomous driving technology through competition
Dev Bot 2 Specifications
- Designed to carry human passenger
- 362 horsepower from two electric motors
- Top speed: ~135 mph (civilian limited to 60 mph)
- 0-60 mph: 4.1 seconds
- Development version with human capacity
Robocar Specifications
- Fully autonomous, no human capacity
- Same powertrain as Dev Bot 2 on rear axle
- Additional powertrain on front axle (four-wheel drive)
- Twice the power of Dev Bot 2
- Used for top speed runs
- Achieved 299 kph maximum speed
Sensor Technology
- Military-grade GPS: accurate to ~2 centimeters
- LIDAR: positioned on corners and sides to detect object positions
- Stereo vision cameras: judge depth like human eyes
- Same sensor setup on both cars
Track Mapping & Navigation
- Silverstone national circuit: 1.5 miles
- Lap time: ~90 seconds from standing start
- Pre-created track map defines edges and permitted areas
- Algorithms determine optimum racing line
- Real-time speed and braking decisions
- Based on tire acceleration capabilities
Safety Systems
- Full live telemetry monitoring
- Safe stop system: remote emergency shutdown button
- Automatic shutdown if car deviates too far from intended line
- Hardware failure protection protocols
Previous Crashes & Issues
- First year of competition included several crashes
- Hardware failure incident: car believed it was in different location
- Acted on bad positional data, resulting in wall collision
Test Drive Experience
- Speed limited to 60 mph with human passenger
- No limitations on acceleration, braking, g-forces
- Car reacts real-time to track conditions
- Adapts to slippery conditions from earlier rain
- Steering wheel moves autonomously
- Electric car sound profile
Competition Formats
- Multiple cars on track simultaneously (traditional race format)
- Time trial basis competitions
- Exploring various autonomous racing formats
- Identical cars provided by Robo Race
- Teams provide software "driver" (few thousand lines of code)
- Focus on autonomous driving rather than car setup
Race Control & Team Access
- AI receives information about other cars for safety
- Company maintains control room oversight for safety
- Teams have no access once race starts
- Only pre-programmed algorithms operate during race
Sport Viability Concerns
- Risk element missing compared to traditional motorsport
- Human drivers push close to limits/redline
- Question whether autonomous racing works as spectator sport
- Business model depends on successful entertainment value
Human Element in Autonomous Racing
- Technology development + entertainment business hybrid
- Human stories focus on background programmers/coders
- Traditional F1 has 1000+ people, only 2 drivers visible
- Autonomous racing highlights coding teams
- Safer limit-pushing without human driver risk
