Hello! I have a tool for my robot with one gripper and one suction cup. I want to do a simulation with both of this picking dynamic parts and place them somewhere else, and when dropping the part i resumes the dynamic state. I got the gripper working but i’m not able to make the suction cup work, even tho it’s a copy-paste of the gripper that do work. ![image.jpg](https://europe1.discourse-cdn.com/flex005/uploads/robotics1/original/2X/1/117ef4b966f0a12c0753a3aedc746d145798d939.jpeg) During the simulation “VPhysicsControl” gets signal enabled when line sensor “VacuumFinder” finds a part, even tho the SR Latch is negative. My experiences there is always problem in the beginning to pick parts that has a dynamic state but this time I cant seem to get i work? Or is it only me having problem with this? ---

Just a thought, If you removed the binding from Vacuumfinder to VPhysicsControl, and add a binding from VDetacher’s child to VPhysicsControl object. Worth a try
