Re: How to control Stewart parallel mechanism through force
Hello, it is difficult to guess what you are trying to achieve. When using force control, you absolutely need some sort of feedback, otherwise you won't be able to do anything. I couldn't see any feedback in your scene. Maybe first try to control your robot's joints in position. Then switch to some...

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.

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...

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...
