I read opensurgery.net, and was impacted. Robot Operation System on Debian Linux system provides motion abilities such as motion-planning and 3D perception. An ROS node program has been given to connect Arduino boards for years. I built a multi-DoF robot arm feathering these abilities, with toy servos, sg90 and MG996r. Can we make a surgery robot by ROS and maker utilities?
A 7DoF robot arm made by Arduino and cheap toy servos. All of them worth of $20. But The arm features motion-planning service.
