Free rolling wheels 1

[RC18]

Hey guys,
I am using ADAMS view and I have a simple model of a robot that is driven by its two front wheels and steers using differential steering.
I know the STEP functions that describe the velocity of the front wheels (therefore, moving the robot). During the motion of the robot, how can I remove the power on the wheels and let it roll? I am imposing a motion on the Revolute Joints, but when I set the velocity to zero, it suddenly stops.

Thanks for your assistance

Hopefully if you think about what you have written you'll see why it stops.

What you need is to DEACTIVATE the velocity motion statement at the time when you want it to stop working.
DEACTIVATE
The DEACTIVATE command turns off a statement that was previously turned on by the ACTIVATE command, or that was active by default.





Cheers

Thank you Greg. Is the DEACTIVATE command available in ADAMS view? From what I've read here on eng-tips, you've recommended using ADAMS Solver. My goal is to deactivate the motion function (speed) after x seconds.

All of the pretty front ends we use are preprocessors that create ADAMS Solver files (.adm). When you use the function builder that is writing in Solver language.
