Using openmanipulator with an AX-12A #218

Closed Lantc26 closed 3 years ago

Lantc26 commented 3 years ago

Hello, we would like to use openmanipulator with an AX-12A. We already saw this post claiming, that no AX-12 servos are supported. We'd like to modify the code to support our robot. We already followed these advices and modified the code to match our robot. At the moment we get this error:

This has probably to do with the unsupported AX12 servo. Thank you in advance

Hi @Lantc26 Please understand that we do not provide a thorough technical support for customizing the product. Since open_manipulator packages are written for X series which runs off of DYNAMIXEL Procotol 2.0, converting them to support Protocol 1.0 will require a moderate level of rewriting source codes. Thank you.

I see. We found a way to control the arm in a different way. So I close this issue now. Thank you anyway.

Hi @Lantc26,

I'm having the same issue. Would you mind sharing the solution you used?

Hi @alex-ssom, @Lantc26 and I used the https://github.com/ROBOTIS-GIT/dynamixel-workbench. We used the controller and operator packages. This is way more basic but we just need our robot/servos to move to specific positions. Therefore it is sufficient.
