What value is used to represent full power on a motor?

The value that is used to represent full power on a motor in many robotics contexts, including VEX Robotics, is 127. This value is based on an 8-bit control system, where the range of possible values for motor speed typically spans from -127 to 127.

In this system, 0 represents no power (the motor is off), while 127 indicates the maximum forward power that the motor can produce. Conversely, values lower than 0 (such as -1 to -127) are used to represent reverse movement. Therefore, 127 is the peak value for full power in one direction, making it the correct answer for representing full power on a motor.
