Smart Motor #

Introduction #

The Smart Motor blocks allow you to control and monitor individual motors or motor groups on your EXP robot. These blocks can spin, stop, or move motors to specific positions, as well as report their velocity, torque, power, and temperature.

Below is a list of available blocks:

spin – Spins the selected motor or motor group indefinitely.
spin for – Spins a motor or motor group for a specific distance in degrees or turns.
spin to position – Spins a motor or motor group to a set position.
stop motor – Stops a specific motor or motor group from spinning.
set motor velocity – Sets the speed of a motor or motor group as a percentage.
set motor position – Sets the position (encoder value) of a motor or motor group.
set motor stopping – Sets the stop behavior (brake, coast, or hold) or the motor or motor group.
set motor max torque – Limits the maximum torque the motor or motor group can apply.
set motor timeout – Limits how long a motor or motor group block waits before giving up if movement is blocked.
motor is done? – Returns a Boolean indicating whether the motor or motor group is no longer spinning.
motor is spinning? – Returns a Boolean indicating whether the motor or motor group is currently spinning.
motor position – Returns the motor’s or motor group’s current rotational position in degrees or turns.
motor velocity – Returns the motor’s or motor group’s current velocity in % or rpm.
motor current – Returns the current drawn by the motor or motor group.
motor power – Returns the amount of electrical power the motor or motor group is consuming.
motor torque – Returns the amount of torque currently being applied by the motor or motor group.
motor efficiency – Returns the current efficiency of the motor or motor group.
motor temperature – Returns the current temperature of the motor or motor group.
