Robotic arms are versatile machines and are great for learning the principles of robotics or even doing some useful hobbyist work. This work can consist of selecting and placing components on circuit boards, packaging boxes or any other element imaginable. But to do this job well, the robotic arm needs more materials than what we tend to see in DIY projects. Pavel Surynek wanted a high-performance robotic arm and the result is RR1: Real Robot One, which features closed-loop feedback for precision and repeatability.
In an open-loop robotic system, the controller only issues positioning commands and receives no feedback. Because it has no feedback, the controller does not know if the position is accurate and cannot actively compensate for issues such as backlash in the motors. Closed-loop feedback provides real-time, real-time position data to the controller, so it can ensure results match commands. RR1 receives closed-loop feedback data from encoders on each of the six joints, which are driven by stepper motors through 3D-printed planetary gearheads.
An Arduino Due board controls stepper motors via driver boards and monitors encoders. It transmits data from the encoder to a computer called RB1: Real Box One and receives control commands in return. The end effector demonstrated is a standard clamp and the rest of the arm is a combination of 3D printed parts and aluminum extrusion. The current version of the RR1 has a maximum reach of 80cm and can lift around 2kg. It's already impressive, but Surynek plans to improve it with an upcoming revision.
