However, when I looked at the BOM I was surprised that the actual arm they use is an incredibly expensive off-the-self arm https://www.trossenrobotics.com/viperx-300
For a much cheaper option take a look at https://github.com/huggingface/lerobot (this is an AI training library/framework) which uses the SO-100 arm https://github.com/TheRobotStudio/SO-ARM100 (one arm is $123). See: https://www.youtube.com/watch?v=n32OmyoQkfs
There's also the Parol6 arm, which is more performant than the SO-100, but more expensive: https://source-robotics.com
