Robotics Worksheet: Gyro and Turning

Robotics lesson 19: The gyro and turning · Set 68 · 40 questions

Robot tip (Count the degrees): Full turn 360°, half turn 180°, right angle 90°. Heading: right adds, left takes away; keep it between 0° and 359° by adding or taking away 360. Equal turns in a full circle = 360 ÷ one turn; time to turn = angle ÷ degrees per second.
