Hi,

I am unable to see length of rigid body frame in MapleSim Examples - Physical Domain  - Multibody - 5 DOF robot? Is there a way to see them?

Thanks

Hi,

I was trying to find the solution for two theta variables in a couple of simultaneous equations (infact this is an iverse kinematics problem for a two link system pendulum).
The following are the initial inputs/equations to be manipulated:


Then I use the folowing command to rearrange for the theta values which I am after:

which gives me the result:

This is all fine until I give in values for l1, l2, x and y:


results:

I have a RootOf in there with a _Z term poping up here and there. I know that this configuration of the two link mechanism in fact dows have a solution and that these numbers are reasonable. Thus I have three questions:

Why does this happen?
What does the "signum" mean here?
how do I go about getting the nummerical values?

Many thanks,

Hi,

I trying to simulate a force sensor on robot arm, but every time I try something, I get nothing from my sensor, can you help me?

 

Here it's my "design":

 

Also, if I add a rigid body I get this error:

Thanks!

 

 

I am building a robot arm,now I want to replace the rigid arm with the flexible arm. How can I control the arm's form?
