Re: .URDF.XACRO file

Hello, V-REP (or its plugins) cannot translate/understand xacro files, so you will have to process them as you mention it. Not sure what the problem with the generated URDF file is. Maybe there is a possibility to translate your URDF file into an SDF file, which can also be read via a V-REP plugin. ...

Re: making copy of UR5withRG2Grasping.ttt , but RG2 is not working

Have a look how the gripper is communicating with the robot: via a string signal. Make sure that the string signal is emitted under the correct signal name.

Re: Export data to Excel or Send them to Matlab

Hello, The first thing to do is collect your data, e.g. inside of a Lua table. Once the data is complete, you can either: write a file with your data (e.g. in csv format) or put your data inside of a string signal . An external application, e.g. a Matlab remote API client, can then read / clear that...

Re: UR5withRG2Grasping.ttt Simulation View Angles shifting

Hello,

check instructions like sim.setInt32Parameter(sim.intparam_current_page,1) in the script attached to object UR5.

Re: Vortex not working

Well, the plugin itself is not using AVX2 at all, nor does it use compile flags towards this. I really can't imaging this is linked to the plugin itself, and not the library it links (i.e. Vortex)

Re: kinematics model of hybrid robot

From what I can see you have best chances if you build the kinematics of your manipulator in following way: Create 3 IK elements that are grouped inside of the same IK group (for simultaneous resolution): base --> revJoint --> revJoint --> prismJoint --> revJoint --> platform --> revJoint --> prismJ...

Re: Inverse Kinematics Question

So that means, you use the same Jacobian but your calculation of sqrt(det(J*JT)) is different? Then one other part of the calculation above must be wrong. You can have a look how V-REP computes this in file v_rep/sourceCode/inverseKinematics/ik/ikGroup.cpp , function CikGroup::getLastManipulabilityV...

Re: UR5 with RG2 gripper grasping status check

Hello, you can check various things that allow you to detect whether the object was grasped or not. For instance: you can check the gripper angle you can use a proximity sensor to check whether a part is in the gripper you could use an appropriately placed force/torque sensor . This is a bit more co...

Re: Parallel robot - IK mode

this collision happens because the red joint's range is not large enough. You can detect this if one of the joints is very close to its limit. Or when IK doesn't fulfill precision requirements. If your IK group doesn't fulfill precision requirements, you can configure your IK group to revert to the ...

Re: kinematics model of hybrid robot

It is very difficult to guess what you are doing or what you are doing wrong. If you need your end-effector to maintain a specific orientation, then exclude the joints that are responsible for that orientation from the IK calculation. You can also introduce auxiliary joints to help IK resolution to ...
