## Summary

A student working on a graduation project wants to recreate the 2015 UW chess-playing robotic arm but cannot find any documentation on the UW website, so they posted asking what actuators the arm uses and what software achieves its smooth, fast movements. The poster believes the arm has a limited range of motion but is still impressive to this day, and hopes to get relevant leads.
