Hello, I use zmqRemoteApi and Python for remote control. I used sim.setJointTargetVelocity to set the speed of both sides of the car to 0.5, but the linear speed obtained using sim.getObjectVelocity differs significantly from the set speed. The result obtained is [-0.09996414184570312, 0.00109076499...

Hi,
I am a university student. I want to train the deep reinforcement learning model DQN, but the server doesn't have a graphical interface. So is there a way to solve this problem?

thank you.

Hello，
I made a car out of several simple geometric models. I find its volume is a little too big, so I want to change its size.
How do I manipulate them to scale down?

Thanks!

hello，

I'm a college student and I want to simulate a 360-degree lidar. What should I do?

I hope I can get help, thank you.

Hello，
I make a wheel using a revolute joint and a cylinder and use the sim.setJointTargetVelocity function to set the speed of the joint. I want to get the linear velocity of the wheel, but I don't know whether the joint uses angular velocity or linear velocity.
I need help.
