A prototype mechanical gripper. This model serves to demonstrate one method of creating a robotic gripper. Having two connectors to each claw allows the claws to always close parallel to each other. With a handle and a trigger, the user can operate the mechanism without the use of electronics to make for an easy to assemble educational model.
Glue Mechanical_Gripper_Frame_1.STL, Mechanical_Gripper_Frame_2.STL and Mechanical_Gripper_Frame_3.STL together to create the frame with the handle.
Mechanical_Gripper_Arm_Gear_1.STL can be printed as a single piece. However, if warping is encountered, Mechanical_Gripper_Arm_Gear_1_Plus_Base.STL and Mechanical_Gripper_Arm_Gear_1_Plus_Top.STL can be printed instead and glued together.
Use M3 screws to attach the components to the frame.
Slide Mechanical_Gripper_Rack_Circle.STL in through the back of the frame.
Edit 13/06/19: Added frame files with holes for screws for those who want to avoid using glue.
