TRC Member userasp9185 showed off some great examples of what you can do with the InterbotiX WidowX Robotic Arm. First asp9185 created a custom IK engine and control software in Visual Studio/C#. The ArbotiX robocontroller running the ROS sketch acts a pass-through, allowing the computer direct control over the servos. The software axxepts XYZ Cartesian coordinates and moves the arm to that position. A forward kinematics solver than confirms the position based on positional feedback values from the servos
The software can now preprocess an image to detect adges and contrast, and then randomly select pixels. The IK algorithm determines the best path to draw the pixel on the paper, allowing the robot arm to draw a version of the photo that was input into the software.
Be sure to check out This gallery for more information on the project and images that the arm produced!
