Re: Facing Problem in Hexapod

Hello,

this is because consecutive links are colliding with each other. Make sure that consecutive links do have a respondable mask that results in 0 when using the boolean AND-operator (i.e. collidableMask1 & collidableMask2 == 0)

Re: Configuration Space/ Joint Space

Hello,

this question does not seem to be directly linked to V-REP.
When you mean a
single random point
, you probably mean a single random node. A node represents a configuration in the configuration space of the robot and is often used in randomized path planning algorithms.

Re: Connecting V-REP to ARM64 architecture board

Hello,

you will first have to decide through which means you want to connect V-REP to your board. There are several possibilities: legacy remote API, B0-based remote API, ROS, BlueZero, or any custom solution (e.g. sockets)

Re: Visualize sensor trace

If you need some kind of transparency, you might also use a point cloud instead of the ocTree, this way you will be able to see the points and through them too. The approach is almost identical as with the ocTree.

Re: Visualize sensor trace

You can also use a ocTree object to represent the seen areas. You will have to create a shape that represents the vision sensor boundaries. Then, each time you want to add a trace , add that shape to the ocTree via sim.insertObjectIntoOctree . Or even simpler: each time you want to add a trace , cop...

Re: Add Vision Sensor Filter via Code

You can use sim.setVisionSensorFilter for that. I wouldn't make too complex things with it, maybe simply enabling/disabling a filter component. If you need more complex operations on vision sensor images, then use the image (or OpenCV) plugin , e.g.: function sysCall_init() visionSensor=sim.getObjec...

Re: Quadricopter following path problems

Try to practice first with a cube that you make float over the floor. You will have to: add a force that compensates for the weight of the cube add a force that corrects for positional errors (e.g. if you want your cube to be able to move to different heights). A P-controller is probably not going t...

Re: How do I extract data from excel to vrep

Hello,

the simplest is probably to export your data as csv-file (comma-separated-values), which Excel allows to do.
Then you can handle that file as a regular text file. To read a text file from Lua, have a look here for instance.

Re: requent no resonse lead to lost of .ttt file

Hello,

unfortunately your file appears to be corrupt, and we can't save it. What V-REP version are you using? What platform? Anything specific about your scene, that might have lead to a crash during save?

Re: Import 3D model shapes with the original orientation via script

Hello, you can't really control the position or orientation of a shape reference frame: the reference frame of a shape is automatically selected to be at the geometric center of the shape. Orientation is also selected to form the smallest bounding box around your shape. But the shape itself (the ver...
