Product Description

Roboteq’s AX3500 is designed to convert commands received from a R/C radio, Analog Joystick, wireless modem, or microcomputer into high voltage and high current output for driving one or two DC motors. Designed for maximal ease-of-installation, it is delivered with all necessary cables and hardware and is ready to use in minutes.

The controller's two channels can either be operated independently or mixed to set the direction and rotation of a vehicle by coordinating the motion on each side of the vehicle. The motors may be operated in open or closed loop speed mode. Using low-cost position sensors, they may also be set to operate as heavy-duty position servos.

The AX3500 version is equipped with quadrature optical encoders inputs for precision speed or position operation. Numerous safety features are incorporated into the controller to ensure reliable and safe operation.

The controller can be reprogrammed in the field with the latest features by downloading new operating software from Roboteq.
