Pulley Power!

For both my automatic curtains as well as my robot arm joint I ended up using GT2 belts and pulleys. But although printing GT2 pulleys is possible, the 3d printed pulleys tend to skip some teeth quite easily when they are used in high torque applications. Just as an experiment I though to give HTD 5M belts a try.

Pulley & Belt Transmission

Admittedly, building a robot arm joint transmission is way more difficult than I expected. But where’s the fun in a simple project? In my last post, I explained why a geared transmission doesn’t work. This week I’ll try a new approach.
