Hi.

I'm using dynamixel_motor package to control my robot.

Often my dynamixel shows over load error because of tough usage. Once this error happans, I have to switch off my dynamixel and switch on again.

This way is not useful,so I would like to restart that dyanamixel through a program after over load error.

Could you tell me how to do this?

It depends on the model of Dynamixel you are using. Some of the newer models (XM and Pro series) have reboot commands builtin. For the others it is a combination of toggling the torque enable register and setting the torque limit register http://forums.trossenrobotics.com/showthread.php?7289-How-to-clear-Dynamixel-Overload-error&p=66440#post66440.

Buggy behavior has also been noted in some AX-12 firmware releases, so the exact ordering of these steps may be different in some configurations http://forums.trossenrobotics.com/showthread.php?7289-How-to-clear-Dynamixel-Overload-error&p=66441#post66441.

Finally, if overload occurs it's usually a good idea to review your design and determine how it can be avoided. I've burnt up MOSFETs on several AX-12s by ignoring and resetting overload errors. At the very least be sure to let the motor cool down if the temperature is also high.
