Understanding Linear Velocities in a Rotational System Simulation Using Simbody

First of all, sorry to post this question during the holiday period, but I'm hoping someone might be able to help. I'm working on a simulation using Simbody where I have a chassis connected to the ground via a free joint, with two motors and wheels attached. The motors apply torque to the wheels, c...

Rotation Matrix notaion

Hi, I've been studying the notation used in Simbody, and I've encountered confusion regarding the transform notation. X_BG is "the transform from frame B to frame G." Vec3 v_B = ~X_GB.R()*v_G; Vec3 v_B = X_BG*v_G ; It seems to suggest that X_BG is a transform from frame B to frame G. Yet, in the cal...

Drone

Hi ,
I am trying to use Simbody for Drone simulation for vertical lift . for drone what kind of joint should put is it free or some thing else .

My drone has four propeller.

Please let me know if i need further information

Few Question regarding setting initial angular velocity to body?

Hi , First, I like to say Simbody is an awesome tool for engineering modelling where accuracy is needed. We are using this to create the digital twin of our robot. Thank you for this speed. I am using simbody for my Project application. When I was playing with the code, I had a few questions. 1. I w...
