Re: Problem with installing UI on V-rep

Hello,

not sure what you are talking about... are you referring to the custom UI plugin?

Re: V-REP and fluids

Hello,

did you have a look at the demo swimming robot, Models/robots/mobile/ACM-R5.ttm?
Have also a look at this buoyancy example scene.

Re: How does the physics engine handle the velocity and force that is computed in the PID controller?

Hello,

yes, the physics engines will handle that situation as when the motor is enabled and the control loop disabled, i.e. the joint will accelerate with the given force/torque until the target velocity is reached.

Re: How to get friction?

Hello,

you should be able to do this by using sim.getContactInfo. But in that case, do not use the Bullet engine, since it will only give you the force normal to the contact surface.

Have also a look at the model Models/other/contact display.ttm

Re: question about vrep

Hello, at simulation start, it can be that some calculation structures need to be first calculated. This is most of the time the reason for a short freeze at simulation start. But the second time you run the same simulation, that freeze should not occure anymore, since the calculation structures (e....

Re: Rotating sensor on robot

Hello,

for a sensor, you would typically not want to dynamically simulate it. So the rotating elements would be non-respondable and static shapes. The joint should be in passive mode. Then you can modify the angular position of your joint with sim.setJointPosition.

Re: simulation slows down with multiple robots

Hello, this really depends on what functionality you are using. The Baxter model has 3 vision sensors. If all 3 are active, then this can generate a significant slow down. Same for some proximity sensors. Make sure to identify the source for your slow down by looking at the calculation times for eac...

Re: Inverse Kinematic with Sawyer

Hello, you can have many things that go wrong. Typically: your adjacent robot links are colliding with each other your robot links have a bad mass and/or inertia. The Vortex engine handles these problems much better, try with Vortex to see if that might be the reason your joint position controller h...

Re: How do I programmatically check if compound shape is convex?

Hello,

you can use sim.getObjectInt32Parameter with sim.shapeintparam_convex or sim.shapeintparam_compound.
