Re: Remotely call threaded script functions

Hi Admin, Thank you very much for your reply. I tried what you said "to execute additional function calls in the remote API client", but got the same "Error: [string -unknown location]:?: Call failed. (simCallScriptFunctionEx on moveBody@BodyDynamics)". I did get any data to conduct tests. And when ...

Remotely call threaded script functions

Hi, I coded a climbing gait of a quadruped robot using IK chain and simRMLMoveToPosition in a threaded script. I am trying to remotely call the created climbing gait as a function from MATLAB. I understand simxCallScriptFunction can only be used to Call non-threaded scripts, and I found simSetThread...

Re: MATLAB-VREP Hokuyo Communication

Hello, I strongly suggest you use the simxCallScriptFunction function, which is much less confusing that using data streams. IF you don't do thing correctly with data streams, you can lose data in-between. Also, you don't show us how you print the COM value on the Matlab side. Cheers Hi Admin, Than...

Re: MATLAB-VREP Hokuyo Communication

Hi Admin, I am trying to read all the positon data of the Center of mass (COM) of my system from vrep to MATALB. I read through all your posts in this question, and followed the solution you gave in your first post trying to do this as follows: In vrep non-threaded side: local c={centerOfMassOfModel...

Re: Yawing Bipedal Robot

Thank you for your quick reply. This is important to understand 'ant hexapod', then improve the codes by using 'simRMLMoveToPosition' instead.

Re: Yawing Bipedal Robot

Hi Admin, I was wondering can you post some explanation of "simMoveToPosition" since there is nothing but a 'DEPRECATED'. Similar to the Lua parameters details for "number result,table_3 newPos,table_4 newQuaternion,table_4 newVel,table_4 newAccel,number timeLeft=simRMLMoveToPosition(number objectHa...

Re: Center of Mass Visualizer data read

Hi Jay, the simplest would be to pack the information needed in a string signal, like for instance: local data={1.23,3.45,5.67} local packed=simPackFloats(data) simSetStringSignal("myData",packed) On Matlab side, you would then use simxGetStringSignal and simxUnpackFloats . Cheers Hi Admin, Thank y...

Center of Mass Visualizer data read

Hi all, I am trying to read the position of the center of mass of my vehicle to MATLAB. I realized that in 'centerOfMassVisulizer' customization script if (totalMass~=0) then local centerOfMassOfModel={miri[1]/totalMass,miri[2]/totalMass,miri[3]/totalMass} local c={centerOfMassOfModel[1],centerOfMas...

Re: Set internal friction of joints

Hi Jay, for 1, if you want to limit the max. velocity of your joints, simply set its target velocity to what is needed. You can also do this programmatically with simSetJointTargetVelocity . About question 2: this will depend on the used physics engine. With Bullet/ODE/Newton, you cannot do this. W...

Set internal friction of joints

Hi, I am simulating a tracked vehicle and modeled each track as five rollers. I need to calculate joints energy consumption of the whole system, I did this by the following two methods: 1. Set desired torque to joints by giving a very high desired velocity (999999) first, read joint velocity and act...
