Let's Build Knex S2 - Ep5 - Robot Project: The Arm

In this episode, we finish up some additions to the control panel to make everything work better, and also come up with a better way to prevent the tape from stretching out due to the weight. Next we get the actual robot arm mostly finished. I wasn't able to make it as originally planned, since I didn't expect it would be as wobbly as it was. Tracks could be built around the first and second link to make it more rigid, but I don't have the space to make such a large circular track. So, I ended up going with a sliding joint for the first joint, which is a lot more stable. It will also fit better into the building area.

"Let's Build Knex Season 2" is a series of videos showing me building a fully mechanical Knex robot arm, which will be programmable and teachable.  This project is mainly just a proof of concept; I'm not sure how accurate and useful it will actually be, but I'll try to make it be as accurate as possible.


I hope you enjoy!
