How to control Stewart parallel mechanism through force

Post by biscuit122 »

I am gonna to control a Stewart parallel platform in force control mode using the function "sin". Here is my model in Vortex, which cannot operate normally in the last half cycle.
Could you help me find the problem?

Thanks.

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 something more complex.

Cheers
