Abstract

Technologies for steering sensors in a payload carrier structure on an autonomous vehicle (AV) are described herein. An example method can include receiving, by a motor control system on the AV, instructions for controlling a motor on the motor control system to reposition the payload carrier structure from a first position to a second position; based on the instructions, sending, by a controller on the motor control system to a motor driver on the motor control system, a command instructing the motor driver to reposition the payload carrier structure from the first position to the second position; sending, by the motor driver to the motor, a control signal generated by the motor driver based on the command, the control signal controlling the motor to reposition the payload carrier structure to the second position; and moving, by the motor, the payload carrier structure and sensors to the second position.
