I don't know if this is the right place to ask this question but I'll give it a try. A friend of mine is using unity 3D to simulate a robot arm, however he's having some troubles when he needs to rotate the robot arm. The arm can already grab stuff with its hands, however seems like sometimes randomly crashes when is rotating the wrist.
Here's an image of the robot arm:
That's the arm he's working on for the simulation, and you can see that every part of the arm is connected through the unity's inheritance system so it can rotate every piece of the robot arm along with the nested parts that follows the inheritance path. However something seems like is failing when it rotates the wrist of the arm.
Three main questions:
- How should be achieved the arm's rotation properly?
- How should be achieved picking up things with the hand of the arm properly?
- How could you make it move by itself on a given point that can reach?
I'm not asking for code or anything like that, just how these 3 things should be done properly in order to have fully functional robot arm simulation like the main concepts behind it.
