Re: Throwing object

Throwing an object is quite difficult, even if it doesn't appear so. The point is that the moment where the object has to be released is crucial. Also how the object is released. I would highly recommend to use a pseudo gripping mechanism where you attach the object via a simple force/torque sensor....

Re: How to set the table that the people won't go through it?

Hello Jian, the model Bill on Path.ttm is a model of a person that will follow a fixed path (that's why it is called Bill on path ). You can either modify the path object, so that Bill doesn't walk through the table, or then you should use a different model of Bill, that has sensors attached. There ...

Re: RG2 gripper Keeps on Falling from Jaco Arm

I guess there are many ways to implement this. How this was implemented in the scene you mention is following: First, we try to reach an approach pose. This is typically a couple of centimeters away from the goal pose. This is handled via path planning functions. That approach pose is normally speci...

Re: Rotation of the RG2 Gripper

It is difficult to visualize what is going on. Can you post a simplified, self-contained scene that illustrates your problem?

Re: VREP Api Remote on Raspberry

Hello Romulo,

I think you will have to compile the remote API library yourself.

Re: CoppeliaSim crashes with Error: signal 11

Hello,

what about removing the Vortex plugin from the CoppeliaSim folder? That should be libsimExtDynamicsVortex.so

Re: RG2 gripper Keeps on Falling from Jaco Arm

From the picture it looks ok. But it is just a picture. Please post the scene.
To make the gripper open/close slower/faster, adjust the variable motorVelocity in the child script attached to the gripper base.

Re: Rotation of the RG2 Gripper

Hello,

what about simply adjusting the position of the robot's last joint, while keeping the other joints fixed?

But if your robot is for instance attached to a mobile platform, then you will have to attach the robot to the platform ba...

Re: Balancing ball PID

Hello Michal, so you basically want to control the inclination of a plate in two directions, so as to control the position in X/Y of a ball on the plate? For that, use something like: baseObject(static) --> revoluteJoint1 --> auxiliaryShape(dynamic) --> revoluteJoint2 --> plate(dynamic) Make sure yo...
