Summary

This is a 3D printable version of my sumobot design at http://sumobotkit.com. It was designed for Nodebots Day in Las Vegas, NV. We were looking for a low cost alternative to expensive robot kits. With a couple of servos and a microcontroller, this is easily under $50. If you need a version that can be easily made in bulk, try the laser cut version in the SVG file!

Instructions

This comes in 7 basic pieces that snap together. There are a couple of options for the top to mount a pinoccio or arduino compatible board and a curved or flat shovel. Otherwise, print two sides and two wheels and one of everything else!
You'll need a 1/2" ball bearing to pop into the hole for the ball caster on the bottom of the front. You can stretch some o-rings over the wheels for additional traction. A 4xAA battery pack will fit snugly in between the tops of the servo motors and the top of the robot.

Dah so close.

Printed off a set of parts and everything but the front scoop fits.

Seems like the front is undersized for the robot :( see photos in the "makes" for an idea of what's going wrong.

Does the Sumo Bot Jr use a remote control?

Hi! I was wondering what size screws to use and the size of the servomotors. Thank you for helping out!
Also, this is for an Engineering project at my high school and I have no clue how to use arduino to write a code..... Any tips available?

Thanks for these! I'm using Makerware to print these. Do you have any recommendations for the Infill and Shell settings?

I've been using 2 shells and 10% infill. At least with PLA it seems plenty strong enough to hold together. well.

Front piece is too small, the holes are almost 1 centimeter closer than they should.
I noticed it until after printing. I printed in PLA using a Replicator 2 with the file generated in Makerware 2.4
Here's a photo of the pieces

Oops, sorry for the dud print! I must have 'fixed' the math in the scad file. I have an updated version of the STL files in my github, but thingiverse isn't letting me upload right now: https://github.com/makenai/sumobot-jr/tree/master/3d_print/sumobothttps://github.com/makenai/sum...
I'll try uploading here again later today.

Hello, thanks for the 3D Printed Sumo Bot... I printed this out but it would seem that the parts don't push together tight so i am assuming one needs to glue it together maybe? If so what did you use? I used ABS and they fit together well just not enough friction to hold them together.

I think that it depends on the printer you have. On mine, it fits together pretty nice and snugly using just pressure. Two options for you:
1) If you want to print again, you can open up the OpenSCAD file and adjust the tab_spacing variable. I think you need to decrease it to make it a tighter fit.
2) Since you printed in ABS, you can make a really great glue out of 'ABS slurry' - that is, take some nail polish remove, and soak a bunch of waste ABS into it until it dissolves in a cloudy liquid. You can then use this to glue your parts together (effectively, it is welding the parts together). ABS slurry howto: http://www.3dsupplyworld.com/magic-abs-acetone-slurry/http://www.3dsupplyworld.com/m...
2a) If you want to glue PLA, I recommend this stuff: http://www.amazon.com/gp/product/B003HNJEY0/ref=oh_details_o07_s00_i00?ie=UTF8&psc=1http://www.amazon.com/gp/produ...

The internet, it works! Thanks! Really thank you!
