Re: Connect two moving objects with rigid link

Not sure why your solution is not elegant with the 25X25 sized floor: you are not required to attach the dummy to the floor just below. The dummy could also hang over the void, but still be attached to one floor element (basically constantly stay attached to one floor element, and only moving the d...

Re: Revolute joint direction of rotation

Both ways of doing are fine. It doesn't really matter. If you look at the joint child from a reference frame attached to the joint base, the child will rotate in one direction. If you look at the joint base from a reference frame attached to the joint child, the base will rotate in the other direct...

Re: Revolute joint direction of rotation

Hi, here is the simplified scene(1). Pay attention to the rotation of the male_joint1 reference frame when +90 deg is set as a target position in respect to default state (target position 0 deg). What may be causing the problem/confusion is the fact that joint is not connected to a fixed object, ins...

Revolute joint direction of rotation

Hi Coppelia, I have a basic question, but it's driving me crazy for a few days now. What's the direction of the rotation of revolute joint? I have read the topic Joint types and operation, and I don't understand what is meant by "... the amount of rotation about their first reference frame 's z-axis...

Re: Connect two moving objects with rigid link

You can use the exact same approach. You will however have to correctly place the dummy attached to the floor before creating the connection. Cheers Hi Coppelia, in simulations I do not know in advance where the connection will occur. Having that in mind, placing dummy on a preset location is not a...

Re: Connect two moving objects with rigid link

Hi Coppelia, I have an additional question! Is it possible (in similar fashion) to form rigid connection with the floor (not with the predefined spot but rather anywhere on the floor). To be more precise, when one half of the robot is rotated and base is facing floor (second image) I want that face ...

Connect two moving objects with rigid link

Hi coppelia! My scene is given on the pictures below. I have two modules, capable of moving in only one direction. What I want to accomplish is when these two modules are close to each other, I want them to align and form rigid connection. When connection is established I want them to continue motio...

Re: Vrep Matlab Synchronous Mode and DTTO Robot

Thank you for your help. I have given up on Matlab/VREP connection and decided to implement everything inside the VREP to bypass these problems. Now everything is working as expected. I have one last question. In my code i have two variables 'e' and 'c', can you tell me how to plot them on the same ...

Re: Vrep Matlab Synchronous Mode and DTTO Robot

Is it possible to do the position control of the joint inside of a joint control callback script, or just apply torque and velocity? Because I am not interested in torque/velocity control but just a position. Or, is it possible to implement behavior of the joint (position) inside a VREP and call it ...
