The controller has been selling briskly since mid-march. User feedback has been phenomenal.

More interestingly, users came up with clever suggestions, many of which have already been added, others are in the drafting board. Some examples:

- Add an analog input so that the motors can be controlled using an analog joystick. Done!

- Add means of monitoring external component temperature or battery voltage. Done!

- Add position mode for creating ultra high torque Jumbo Servos. Done and working well!

- Add Closed Loop speed control using tachometer feedback. Working!

- Add mean of plotting in real-time on a PC the R/C joystick capture to monitor quality and range of received pulsed. Done!

- Add way of attaching multiple controller to a single serial port. Coming Soon!

The manual is now 130 pages long. The web site has been refreshed.

Please come to and let me know how to make the controller even better.


Thank you to the many of you who commented on Roboteq's new motor controller. This was very encouraging after all the work that went into this design.

Some of you said that there may not be enough Amps. With some extra testing and sofware tweaking it will now deliver up to 120 controlled Amps (up from 60A in the original spec).

I also thought of adding sensors for motor temperature and a few other improvements.

Please come back to check it out at and let me know what you think. Good ideas are always welcome.


While this may sound like a cheap commercial, I have recently completed work on a motor controller to which I have given my best nights and week-ends for the past many months. See

The project grew out of a sincere desire to do something "better" than anything else, particularly if one is interested in creating robots with more brains and AI capabilities.

I am curious to hear what the experts in this forum think of it. Since the unit can be easily reprogrammed (even after is has been shipped in the field) I am also looking for features ideas that I could add to make it even better.

Cheers Cosma
