Double actuated Joints

Post by masoud.javid.j »

Hi,
I am trying to model a hand robot in CoppeliaSim that has 3 joints in each finger. 2 of the joints are coupled together by a cable and a motor is actuating them. So, whenever the motor rotates it is rotating both joints (like pulleys and cable mechanisms in which one of the pulleys is actuated by a motor and connected to the other one by a cable and the other one is rotating). Does anyone know how this can be done in Coppeliasim?

Hello,

if you use the MuJoCo engine in CoppeliaSim, you can link 2 or more joints via a linear equation. In the joint properties dialog, select Dependent mode for the joint, then edit the dependency equation. One of the joints needs to be in dynamic mode.

Have a look at the demo scene scenes/gears.ttt

Cheers
