Vision sensor questions

Hello, I have some questions about the way perspective vision sensors are implemented in VREP. 1) I see there is only one entry in angle of view. Does this mean I cannot have different angles in x and y directions? 2) Is there a fixed focal length? I need a way to translate image patch size to image...

Kinect depth values not matching actual distance

Hello, I have the following problem. I have positioned a kinect sensor 0.4780m away from the floor facing downwards (i.e. z=0.4780). However when I access the depth image (using simxGetVisionSensorDepthBuffer) I find that the values returned range between 0.15 to 0.17. The code for depth image acces...

Strange behaviour-Prismatic joint rotates around its z-axis

Hi, I am trying to build a simple cart-pole system. I am using a prismatic joint to move the cart and a revolute joint that holds the pole. When I simulate the setup using bullet physics engine I see that the prismatic joint is slightly rotated wrt to its z-axis as if dragged down by the pole's weig...
