Thread Subject: 2r Planar robot arms simulation

I am trying to simulate a 2R 2DOF robotic arms which traces alphabets on x-y co ordinates. I need some help in simulating the arms and the trace path of the end effector. I don't have any problem in the IK. All I need to know is how to simulate the graph and the bars representing the arms of the robot. I also need some help in fixing an end of the first link (keeping it as base) and joining the second link to the first link (to create a revolute joint). It'll be of immense help if any one can post the URL of example simulation.

Venkat,

I recommend looking at SimMechanics. This product includes a visualization tool that will let you animate your robot. All you have to do is specify the dimensions of the links and how they are attached together.

Look at a few of my submissions on the central for examples using pendulum or a hopig robot.
