This is the Sager Engineering robotic arm. While it unfortunately lacks a proper name, it makes up for that with its usefulness. For example, it can pass me (Matthew Sager) the salt when no one else is home, given I put it and all of its supporting hardware on the table, wire everything correctly, probably need to rewire, boot it up, calibrate it, and then give it specific instructions on what to do, but after that its pretty much effortless.
