Title: Kinematics of a 3DOF Induatrial Robot
Post by: compgeek on January 19, 2011, 12:35:05 PM
Hello All,

I am new to this group and also to the topic of robotics. I have got an assignment to do regarding the "Kinematics of an Industrial Robot" with 3 degrees of freedom(dof). It should be a Matlab code and the trajectory path is to be plotted.
I would like to ask if some one helps me with this. I actually have less time to study all the topics regarding the implementation.
Can anyone helps me with this assignment. I will be very greatful for them..

Thank You in advance....
 :)

Although I'm not going to help directly with your assignment (you'll learn more if I don't!) you still need to be more specific.  For instance, "DOF" can be rotational, translational (aka "prismatic"), helical, and a whole bunch of other things (which are almost always reduced to rotational/prismatic, but...) 

So what are the DOFs?  Are you doing forward kinematics (from joint variables to (x,y,z)) or inverse kinematics (from (x,y,z) to joint variables)?  What else do you know about the robot?

I also assume you're trying to make matlab code that takes in some parameters (either joint variables or (x,y,z)) and spits out the other paramters, right?

I can offer a few hints if you give more information.  My best advice to you, though, would be to start with a simpler case, say a 2-link planar robot arm with two rotational DOF, and try to do the kinematics for it.  Then just generalize what you learned to your 3DOF robot.
