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.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
