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
