What is this video series about? I'm building a robot gripper arm from scratch! Follow me on my journey as I make a breakthrough, hit a wall, and even check out what parts I'm using!
Special thanks to Designatronics for sending sample parts to test out! If you're also building a homemade robot, work with automation in manufacturing, or are a remote control vehicle enthusiast they have a huge assortment of high quality parts to choose from!

I rebuilt the base of the robot arm so it could support a lot more weight. I added a 2nd motor synchronized with the first to generate a lot more torque to move the arm closer to the "shoulder" and also above the elbow (or "forearm").
The pulleys and belts from Designatronics are found here:

I can only use 3 driver control boards at the moment but the MCP23017 chips I purchased should do the trick. I'll cover that in the next video since there are a lot of RPi updates I have to finish before that'll work.
I'll add the link to the source of the Python code I started with as a reference when I find it (I found it a month ago but can't remember where). I modified it to run 2 motors in sync.
I added a poll at the end of the video as I would really like your feedback - are you here for the robotics, video game content, or all of it!
