Slider driving an RPR Dyad

1.We design a Motion to move a gripper in time with the rest of the machine.
2.A Slide-Joint is added to define the direction of motion for the gripper.
3.The gripper is mounted to a sliding block and it slides along a slide rail.
4.A Pin is mounted in the gripper – shown in blue. This is an R Joint of the Dyad
5.A link – in red – is mounted to pivot on the machine frame. This is an R Joint.
6.The pin is mounted in a slot cut into the red link – the P joint.


A 2D-Cam, (groove cam) drives the red link.


A Design-Set was used to improve the initial layout of the kinematic-chain.
