Source Code and Arm Construction
The source code is available in our Github repository.
It contains the library code for the ROS1 interface, the servo driver, as well as instructions on how to test the arm.
We also make available the 3D part files in Autodesk Inventor format, and list of mechanical elements (screw, nuts, washers, bearings, etc) used for it’s construction.
ROS Integration and Simulation
We provide a ROS1 interface for easy test and use of the arm, with examples of message publishing in either Python or command line.It allows to use a simulator inside RVIZ, that closely mimics the physical arm behavior.
