Robotics Worksheet: Wheels, Legs and Tracks

Robotics lesson 11: Wheels, legs and tracks · Set 277 · 40 questions

Robot tip (Ground decides): Wheels: smooth flat ground. Tracks: mud, sand, snow. Legs: gaps and stepping places. Propellers: air and water. Two-wheel steering: both wheels forward at the same speed → straight; left faster → curves right; right faster → curves left. One wheel stopped → turns towards the stopped wheel; wheels in opposite directions → spins on the spot.
