Feedback on My Custom IC/Mechanical Robot Device Built from Scratch (YouTube Video)

I have developed my own IC/mechanical robot device purely from scratch, and here's the video:

What do you thinks?

PS: This is my first post, so sorry if it's the wrong category.

Andy, that is a cool robot you made and I really like the pincher!

Awesome -- is it autonomous, or are you controlling it remotely, or is it following a set of pre-programmed instructions. Not sure what "electromechanically programmed" means (but that might just be my ignorance showing .

That looks like a Raspberry PI on top -- doesn't it run the battery down pretty fast? Is that a WiFi plugged into one of the PI USB ports? Is that for remote control, or for updating the task instructions or for relaying back sensor data or ???

Nice job!
