This project is a simple robot claw that could be added to many robotics projects. It is meant to show a basic geometry and to give people a head start on building a claw to meet their project's needs.

This model was 3D printed on an UP! machine, but should work just as well on a Makerbot, RepRap, or other such device.

Step 1: Necessary tools and materials

The only materials needed to build this are a few pieces of hardware and a little bit of ABS (or PLA) plastic. Specifically:

- 8x M4 screws (length of about 14mm)
- 8x M4 nuts
- 4x small washers to fit M4 screws
- available spool of plastic

The main tool needed is a 3D ptinter. However, the parts could probably be adapted to to work with a laser cutter since they are all 2D planar extrusions. Besides your tool of choice for the plastic pieces, all you should need is a screwdriver to assemble the claw.

Wondered if you had updated this project to include the motor?

We fabricated this design and found the fit somewhat sloppy.

Our group at Rhodes State College is adapting this design for a robot

project we are building.

the main body, the main left gear, the main right gear, the tall shaft, and the support link are messing up. could you please try to fix them?

Fixed the base plate here :http://cloud.netfabb.com/?key=c4a66b1d666289ecdf6b10c63470871898707&fixedfile=1

One other point is that as the shaft tall and short print on their sides they are pretty hard to get them to come out as there is so little contact with the heat bed. Can these be put flat?

Thanks,

Hi the main body stl seems to have some problems. slic3r says that it has not layers and cant generate it.. still learing the software packages to fix it my self.

can you re-upload?

ta,

B
nice, do you have any plans to drive these gears with a motor?

Yes. I am currently designing/building a version that attaches a 9g servo to one of the gears.

I'll keep you updated as I make some more progress!
