Build a Mechanical Claw

Make a 3 finger claw to grab objects from any direction moving a single straw.

Each finger of this mechanical claw is a 4 bar linkage where one of the joints is a prismatic joint, which allows the machine to be handled by pushing and pulling a straw through a connector.

This model has 3 but you can choose any number of fingers you want by using and combining the connectors. You can also extend the claw with an arm made out of a polyhedron of your choice.
