Re: Summit XL mobile platform by Robotnik
Hi I am working on the simulation of the Summit Xl on V Rep. I saw this video and I want to know the steps done in order to have this model working as on the video. Thank you
Re: Summit XL mobile platform by Robotnik
Hello,
the video was done by user mabemon, that you may contact to obtain the model. But as far as I know the model is currently still quite approximate (i.e. the vehicle is a single rigid entity, no spring/damping in the wheel arms).
Cheers

Hi,
I want to ask about the PID control in the dynamic properties of joints. What do we use them for exactly? I mean what do they
affect?
Thank you

Hi,
the PID controller is usually used to control a joint in position (i.e. if you need to keep the joint follow a desired position). Most of the time, only the P component of the PID is used.

Hello,
I am also working with the Summit XL mobile platform at Universidad Politécnica de Madrid.
Is there a way that you can share your model with us?
Thank you very much.

Hi,
Thank you for the answer but I would like to know what does the derivate position do to the joint performance?
I have one more thing please, I am doing frction essays on V Rep with the Summit XL model, with both Billet and ODE, and I am wondering why the robot cannot climb more than 33 degrees almost whereas the real robot can go up to 45 degree slope.
Thank you very much

Re: Summit XL mobile platform by Robotnik
Have a look at how a PID controller works.
Then, your simulation in the mentioned situation will only be as good as the model and the used physics engine. A physics engine will never compute exact results, actually they are quite approximate. And you can always adjust the friction parameters of the wheels or the ground.

Hi
I am currently trying to make a controller for the Summit XL. Are there an article or code where I can find the dynamic model of the summit XL?
