Summary

This is a first prototype for a motorized wrist (pan-tilt), as part of my research at the Rijksakademie.

2 motors can comtrol the Right and Left [part-001] bevel gears via GT2 timing belts
Rotations on the same direction will cause [part-004] to spin in tilt mode, while movements in opposite directions will produce pan movements. (combination of both are possible)

[part-006] attaches with screws to the [part-004] bevel gear, through the [part-005] mount, via a 50x65x7mm ball-bearings. (https://www.amazon.nl/dp/B09SCN3DQ7?ref=ppx_yo2ov_dt_b_product_details&language=en_GB&th=1)

10x26x8mm ball bearings connects [part-004] and the 2 [part-004] with the cener piece [part-002], using 10 mm rods.

Threaded Inserts allow the use of M3*4.6x5.7mm screws.
