Re: Motion planning only works without collision detection
Hi coppelia, I changed the stepsize to 0.005, but still there is a collision with the object most of the time. Also, I turned on minimum distance, this made path finding impossible apparently. Is there anything else I could try? The robot only moves up to drop the box again, because this is one of t...

Re: Motion planning only works without collision detection
Hi coppelia, in the meantime I worked a lot on the project. I got everything to work with the convex hulls, that was a great idea. Now there are still some problems. First, the Motion Planning Task does not choose exactly the same path every simulation. I think this is natural. But sometimes the gri...

Re: Motion planning only works without collision detection
Hi coppelia, thanks for your help. I added some convex hulls and I think it might work like you suggested, but first, there is another problem to solve. Even when I make all parts of the gripper non-collidable there is still a collision detected in there, right from the beginning. Do you know any po...

Re: Motion planning only works without collision detection
Hello coppelia, The floor-collision is fixed. I moved the robot up a little bit. Defining a second collection just shifted the collision from floor-base to base-link1. For the gripper, I would like to try building a bounding volume, but I am not sure how to do it. I cannot just put a big cuboid arou...

Re: Motion planning only works without collision detection
Hi coppelia, thanks for your help! Unfortunately, that doesn't make it any easier :) I changed the self-collection indicators of all my parts, so every two parts touching each other have a difference of 1. That is the right way to do it, isn't it? But still I get self-collision in the gripper and co...

Re: Motion planning only works without collision detection
Hi coppelia, it seems like not everything works as expected earlier. At the moment, no collisions are detected at all and the robot moves 'through' itself and the floor. I checked all object properties and everything is collidable. Collision detection is turned on. I don't know what else to check. C...

Re: Motion planning only works without collision detection
Hi, I created collision objects for both cases. And in both cases the whole robot changes color right at the beginning. So I think you are right, there is constant collision. But the problem must lie in the definition of collision, right? Of course the parts of the robot touch, but I don't want him ...

Motion planning only works without collision detection
Hi everyone, I need help regarding motion planning. I have a 6 DOF robot, which is able to plan a path to a certain target and move there. I used motionplanningdemo1 as a template. However, this only works, as long as I have collision detection turned off and in some cases the robot will move 'throu...
