This is an example of something that is going on in a lab right now and has the potential to become a really big product. It can become:
- a robot to help professional movers transport stuff
- a robotic domestic helper for everyday tasks and for moving heavy things around
- a robot for space exploration
- a robotic waiter for serving drinks in bars and restaurants
- a game for kids
I don't know anything about marketability, cost of production and the limitations of the technology, but this can become (very) big.
