Re: requent no resonse lead to lost of .ttt file

Hi,

My Vrep version is 3.6.2 64bit on windows 10 Home 64bit.

It happens much frequently these days when I save a file or after a while.

Re: Why doesn't my joint track the desired position?

Hi all,
I have solved this problem. It is resulted from the transformation between radian and degree unit. In LUA script, we should set the target position for revolute joint using radian unit instead of degree. Due to the copyright protection, I delete the .ttt model. Thanks.

Why doesn't my joint track the desired position?

In this scene, I used function sim.setJointTargetPosition to force hipJoint3 and hipJoint4 reaching desired position. But the final position does not equal the given value. So could you tell me how to solve it? Additionally, driveJoint1 , driveJoint2 , ..., and driveJoint6 reach their accurate targe...

How to sent data to Vrep from Matlab

I have tried codes in Vrep side to receive data from Matlab in a Synchronous mode. function sysCall_init() s=0 lastReceivedFX=-1 lastReceivedPos=-1 end function sysCall_actuation() local packedFX=sim.getStringSignal('packedFX') if packedFX then sim.clearStringSignal('packedFX') packedFX=sim.unpackFl...

An asynchronous non-blocking remote exchanging between Vrep and Matlab

I have written low-level controller through Lua in Vrep and optimized APPs in Matlab to get optimal kinematic parameters. In this process, both Matlab and Vrep need to set string signals and get string signals between each other. The code in Matlab is shown as an example. packedFoot=vrep.simxPackFlo...

You haven't defined any IK groups or IK elements! Check maybe this tutorial.

Cheers
Thanks for your help. It really made sense. Very appreciated!

Re: Why does dummies not follow their parent object's motion?

All 6 legs are individually controlled by moving the foot target dummies in relation to the hexa_base dummy. The hexa_base dummy is used to additionally allow for a different height or rotation of the body in relation to all feet. e.g. if all feet target dummies are left untouched, but you simply m...

Please post the code in your callback
Thanks for your reply. I already found original mistake that joint type had been set to kinematic mode instead of torque mode.

Re: Why does dummies not follow their parent object's motion?

Hello, in the hexapod example, IK works exactly as with any other dynamically enabled and IK controlled robot: the target dummy is moved to a desired position/orientation, and the tip dummy will follow. Cheers Yeah, I know that. But in the moving process, dummy 'hexa_base' is set to move relative t...
