In task5_v1 and task5_v2, when the robot approaches an object and tries to grab it, the whole simulation freezes. This happens both when we try to pick up any of the puzzle peace and when we try to push them along the table surface, always after closing the robot jaws around the object. Have you noticed similar behaviour? This problem arises not only when we use our actual code but also when we test the scenarios using a simple gui, which implies the problem would lie within the simulator itself.

Or could it be that the gripping of objects is not allowed in task 5? That the puzzle peaces have to be pushed into the target area with the end effector jaws closed?

Thank you in advance for your help.

there was a memory access error when collecting contact points from the physics engine. this bug will be fixed in the soon to be released euroc-c2s1-simulator_1.0.10_i386.deb.

thanks for finding this!

Thank you for the quick fix! I would also like to clear up another question I have regarding task 5. At least in task5_v1 the puzzle peaces have a clear order in which they have to be placed into the fixture. Is this always the case or are ambiguities allowed? For example, if the puzzle peaces are straight blocks of 4 boxes each, their order of placement can clearly be chosen freely.

Thank you in advance for your help.

Hi,

As the evaluated goal of the task is only the final placement of the puzzle pieces, the order of placement is not important. Actually in task5_v2 you have multiple possibilities for the assembly.
