Potentially! Although, keep in mind the payload capacity is 500g, so it would have to be a light camera.

Ah, unfortunately I ended up moving on to other projects after this video.

This is a great question. The short answer is that both companies are reputable, but have different strong suites. Ufactory started as a hobbyist robot arm company, and then developed into an industrial robot arm company. Elephant robotics started out as an industrial robot arm company, and this is their first entrance to the hobbyist space. For that reason, I would say that the ufactory hobbyist arms are likely going to be a bit more accurate and have better software support. This seems to be changing though, and as always, it depends on your use case.

they launch a new mycobot for Arduino only 499usd, i guess it is more affoardable.

Thank you for the heads up, I've removed it. I think the link shortener I had used must have been compromised.

It's a good question! Traditionally, robot arms have been used with few sensors as input, mostly offering their flexibility in reprogramming repetitive movements. However these days, with the deep learning revolution, it's becoming possible to operate in unconstrained environments and perform tasks that were previously thought too complex for automation. That's a bit of a non answer, but my point is that the sky is becoming the limit. Think about human heavy tasks (such as sorting recycling material) and think about how deep learning + robots can be applied.
