Homework 1 Task 1

Beitrag von MaMö » 2. Nov 2013 21:50

I have some questions about Homework 1 and hope for some answers here :D

1.1 c) Is the state vector q our vector of the q1-q4 introduced at the top?

1.1 e) What does "shape of the manifold" exactly mean?

Hey MaMö!

I'd agree on your guess concerning the task 1.1 c). There, they talk about "robot"… it would make a lot of sense to compute the jacobian to q1-q4 from "our" robot given in task 1.1! Maybe you could help me a bit out on task 1.1 a)… what about that coordinate system in the side view?

Best,

Hey MaMö!

It's me again… to 1.1) e); the shape of the manifold is simply the shape of the operable working space for the robot arm.
I think so at least and this makes perfect sense for me.

Best,

Hey,

thank you for your reply :D
For 1.1 a) I think the coordinate system in the side view just shows how our robot stays in the room (bootom of q1 / x_base)
