Robotics Cheat Sheet

# The numbers are for the pins used on the Raspberry Pi board.
# Make sure your numbers match your wiring!
robby = Robot(left=(4, 14), right=(17, 18))

Code	Variant	What It Does
robby.forward()		Makes both wheels turn at the same rate in the forward direction at maximum speed.
	robby.forward(speed=1)	Makes both wheels turn forward at top speed. Use a smaller number to go slower.
	robby.forward(curve_left=1)	Makes the wheels turn left. Use a smaller number to go forward and left.
	robby.forward(curve_right=1)	Makes the wheels turn right. Use a smaller number to go forward and right.
robby.backward()		Makes both wheels turn at the same rate in the backward direction at maximum speed.
	robby.backward(speed=1)	Makes both wheels turn backward at top speed. Use a smaller number to go slower.
	robby.backward(curve_left=1)	Makes the wheels turn left. Use a smaller number to go backward and left.
	robby.backward(curve_right=1)	Makes the wheels turn right. Use a smaller number to go backward and right.
robby.reverse()		Reverse the robot’s current motor directions. If the robot is currently running full speed forward, it will run full speed backward. If the robot is turning left at half-speed, it will turn right at half-speed. If the robot is currently stopped it will remain stopped.
robby.stop()		Stop the robot’s motion.
robby.left()		Makes both wheels turn so that the robot turns left at maximum speed.
	robby.left(speed=1)	Use a smaller number go left more slowly.
robby.right()		Makes both wheels turn so that the robot turns right at maximum speed.
	robby.right(speed=1)	Use a smaller number go right more slowly.
