Making an autocorrect mini golf club (part 1)

Summary by Krater

The creator builds an auto-aiming mini golf club using a 5-axis CNC machine, worm gears, custom 3D-printed parts, a BLDC motor, and OptiTrack motion capture cameras, eventually programming it to successfully hit balls into the hole automatically.

Answers: How do you build an auto-aiming mini golf club?

• Building an auto-aiming mini golf club
• OptiTrack motion capture for tracking club and ball
• Machining 5-axis parts on a Tormach CNC
• Counteracting motor torque inertia with counterweights and rubber bands
• Programming club control software to eliminate latency and torque issues

What it concludes

• Attaching a rubber band between the putter head and the counterweight solves backlash issues without adding overly complicated mechanisms.
• Using OptiTrack cameras with retroreflective markers allows precise real-time tracking of the club head, ball, and targets in space.
• Modifying the motor with inertia rings and a static counterweight successfully cancels out motor reaction torque during swings.
• An auto-aiming putter requires synchronized tracking of the club's position, rotation, and target location to hit the ball into the hole.
