Designing a Bolt Tightening Robot

This prototype robot was a lot of fun to design and make. The movement is based on a CoreXY motion system that uses two belts and two stepper motors for very fast movement in the X and Y direction.

I designed the bolt detection subassembly and bolt tightening subassembly to include mounts for two additional stepper motors, one endstop switch, one micro-LIDAR sensor and a custom 3D-printed rack and pinion that would raise and lower the bolt tightening assembly.

Mechatronics

Date

Programming and integrating the sensors and motors to the Arduino mega was the hardest part of the project with custom code needed to alter the configuration of the micro-LIDAR hardware.

Prototype was designed, built, and programmed in about six months.
