Is finished plywood a comparable prototyping substitute for polyoxymethylene?

I'm working on a robot with a team, and we're building our robot out of acetal polyoxymethylene (POM) (specifically, delrin) plastic. However, we'd like to prototype the robot before we build it out of POM, as POM is somewhat expensive. There are…

Is this large bipedal robot real or realizable?

I saw this link today. This robot seems real, but redditors on a reddit thread argued that it might be CGI. It doesn't seem unfeasible to make such as robot IMO. There isn't anything out of the norm from the video except the size. Plus, there exist…

What is the best to track an object and its relative position in field?

I understand this is very conceptual. I am working on a system when I am trying to track the path taken by an object as it moves across a field. Imagine a maze built on roughly the size of a football pitch. I want to be able to track where someone…
