The Robotbit expansion board not only extends some IOs of the Future board with DuPont pins, but also has a motor and a servo drive on the board. So in this tutorial, we will learn to make servos and motors work.

Programming Blocks

Block	Introduction
	Establish the Robotbit's IIC communication. It must be initialized before use.
	Set the speed of the motor (positive and negative determine the direction of rotation)
	Stop all motors
	Set the angle of the blue 9g motor (from 0 to 180 degrees)
	Set the angle of the 9g geekservo motor (from -45 to 225 degrees)
	Set the angle of the geekservo 2kg motor (from 0 to 360 degrees)
	Make the stepper motor rotate according to the angle (positive and negative determine the direction of rotation)

Example

If the Robotbit cannot be detected during initialization, the following warning will pop up and block the program. After the expansion board is plugged in, the program will continue to execute

Since the power supply of the motor and servo drive interface comes from the lithium battery on the Robotbit, it is necessary to turn on the power switch of Robotbit
