I watched the following video three months ago and was shocked:

It just looks amazing, which made me want to build one myself to understand how they work. People say building a robotic arm is difficult, but I didn't know. It's always the best way to learn something is to build it right?

Here is the project's GitHub repository: GitHub

The web interface was the most impressive part for me. You should check it out. It's so simple and intuitive yet it uses vanilla JavaScript!

During the video, he mentioned the FOC control PCB was mofiied from the following robotic arm project:

This is way beyond the DIY level. This precision is just insane.

Both robotic arms are similar. Here are some of the features of the robotic arms:

  • Open Source (hardware, software, and web interface)
  • 6 DOF
  • Stepper Motors
  • Harmonic Drive
  • Aluminum Frame

Here is another robotic arm project that I found interesting:

This one uses planetary gearboxes instead of harmonic drives, and you can buy one.

Robot Kits

I read the FAQ and thought they are really pusshing hard to price it as low as possible. The motor package costs around $730 and the robot kit costs around $1,190.
