Robot MarketPlace - RoboteQ AX2550 Dual Channel 120A Robot Controller

This item is not recommended for new designs. Please use VDC2450 for new projects.

Roboteq's AX2550 controller 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 operate 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 controller can be reprogrammed in the field with the latest features by downloading new operating software from Roboteq.

I've had over a dozen of these controllers in robots my company manufactures. Every single one of them failed within the first four months of use. Roboteq is happy to accept more money from you to send you a rebuilt unit, but has not been able to diagnose the problem. Having to replace these failed controllers has cost my company thousands of dollars. It's not just the cost of the rebuilt unit - it's the cost of getting the (very large) robot back to my shop to replace the failed controller.

I finally gave up on Roboteq and switched to another controller. I now have 19 robots in the field for over a year without any problems. I won't mention the name/brand of the other controller so I don't seem like I'm trying to plug another brand; I'm just trying to help people avoid making the same mistake I made.

The ax2550 is a great controller. We used 2 or them to power 3 T74 motors to turn a 26 foot diameter table with 6K pounds of people, and sets. The controller has 6 Guage wires to handle some serious current. I have not tried the monitoring software yet, but it could be very usefull to determine where your limits are.
