raspcatbot (Raspberry caterpillar robot) forum thread:

Slowmo of raspcatbot passing, 100× slower than real, only 1.14m/s here:

Bring your own light and monochrome global shutter camera / free running 1774rpm(!), 6.04m/s with 65mm wheel

On left 2.2" display, Raspberry Pi3A+ and L298N motor driver / with 330rpm motors steep uphill

front view video from 22.5km/h toy train …

… slightly faster than 5m/s (18km/h) raspcatbot target speed.
Just to get an idea of what autonomous line following at maximal speed will have to deal with.

1kg raspcatbot running (with steel wire rope) on 1.25m radius around screw in garage floor.
Speed 3.24m/s or 11.65km/h, kinetic energy 0.5*m*v² = 5.25 Joule, centripetal force m*v²/r = 8.4 kg*m/s²

Loosing big outrunner motor wheel with bullet at 60km/h can be dangerous for top mounted camera ;-)

Arduecat (Arduino Due Caterpillar robot)
full stop back wheelies
• U-turn w/o speed (>2m/s) reduction
• just swap one motor's direction for some time
• slowed down by factor 90/25=3.6
90fps slowmo youtube video
• positions at start of (overshooted) U-turn, at 90°, 180° and finally before going straight again
Arduebot can do similar U-turn
