Ryoba Saw Robot

This is a currently non-functioning robot, designed to rip cut a common 2x4 board down the middle autonomously.

It seems that the springs holding the assembly in tension are too weak. Also a stronger motor might be necessary.

If you like the concept, please try building one, or somethings similar, so we can get the robot functioning!

12v DC motor

Misc extension springs

Short wood screws

limit switch

Elegoo arduino kit

The frame measures 7" x 5 1/2" x 6". I built it out of plywood with rabbet joints in keeping with the woodworking theme, but a laser cut or 3D printed frame would work just as well.

The 4" side blocks have four bearings set on the outside, while the 2" sides have two mounted in the middle. Another 3" piece with a Dado cut acts as a riser for the springs to attach.

The arms are attached to the frame with more 608zz bearings on the bottom. For where the blade attaches, I cut a kerf to the desired depth using the saw blade to get a perfect fit.

The motor mount is made but drilling a hole with a 1" forstner bit, then making an opening using a band saw. this allows for a tight fit with adjustability. The cam gear was roughly drawn and cut out on the bandsaw as a test piece. This is secured on the motor shaft using two brad nails on the key surface.

The motor and limit switch are connected to an arduino with an L293D chip, which is included with the Elegoo kit.

Don't worry, it doesn't work, but it looks cool! Set in on the shelf, ruminate on it, and let me know if you think of any possible solutions.
