I'd rather see the whole track from the top than the current 1st person'ish view. A toggle between different camera modes might be the best option.

Would be superb to build the sim into a docker image runnable on a server. Would open interesting possibilities!

Based on this it might be possible!

Found a Unity3D docker image: https://hub.docker.com/r/gableroux/unity3d/

Lap timer script could report elapsed time at each spline node.

For example pressing R starts a race:

1. disable all motors
2. move cars to starting positions (possibly using the best lap times for the order)
3. reset lap times and set timer to race mode
4. show race lights
5. enable motors and start timers
6. show winner after n laps

Would be great to see current speed. We might even (optionally) imprint that on the output frame top row to help with bot development. Estimating speed on the bot code would be great and to be able to compare the estimate with actual.

• instantiate cars when clients connect
• fix lap timer

Should be removed, but most often doesn't :)

Made some real life measurements:

Track dimensions 4m * 6m.
Car dimensions 24cm * 13cm
Acceleration tests:
0.5 seconds full throttle then zero throttle => car moves 4.0m
0.5 seconds full throttle then full brake => car moves 1.15m
1.0 seconds full throttle then full brake => car moves 3.75m
Turning circle:
throttle at 0.1 => turning circle outer distance 1.2m
throttle at 0.5 => drifting around the room out of control (floor more slippery than actual track)

• Track texture
• Stream camera FOV
• Track width: 90cm
• Car specs: https://latrax.com/products/rally?t=specs

In real life, car performance varies quite a lot. For instance:

• motor torque and steering servo responsiveness depends on battery voltage
• camera colors (white balance, lightness etc) depend on lighting and white balance setting on the camera
• there's likely a varying delay in steering and throttle
