Summary

The mePed Quadruped Robot is an open source robot for anyone who wants to build an inexpensive, 8 degree of freedom, walking robot.

The DXF file is laid out for a 300mm x 200mm laser cutter using either 3mm or 1/8" sheet material for the parts. I used 1/8" Baltic Birch plywood for this build.

The build requires 40ea M3x10mm screws, 16ea M3x12mm Screws, 24ea M3 hex nuts, and 32ea M3 Nyloc hex nuts. Fewer nylocs and more plain hex nuts can be used but I prefer nylocs because they never loosen and they don't cost much more than plain nuts.

If you have any questions or suggestions, please drop me a line. I'll be continuing to advance the design and release more documentation, sample programs, and details as I have time.

The servo retainers and a few design concepts are inspired by/borrowed from the awesome meArm: http://www.thingiverse.com/thing:360108

Would you happen to have the code for this. thx

Hello, you can find the source code on the official mePed website, www.meped.io

What kind of servos did you use?

I prefer to use the MG90S metal gear servos.

Hi Spierce Tech.
Originally I was just going start by printing the legs, because I do like the looks of the kit in wood. Due to my paws though. A parallel plate was damaged when I removed it. So, more of the kit will have to be printed. I would however like to make a suggestion, modification for the printed version. Nut retainers, I am having problems with the nuts falling out before I can get the screws threaded. Again due to the size of my paws. Finding just a dab of wood glue helps. Looking at ordering in a spool of wood pla seeing if I can find a finish to match.
Wondering if there is a date in mind for the software release?

Came up with the scale settings of 25.432 in Cura using original wood for comparison, and calipered them out. I purchased the V.2.0 kit at 2016 PDX OMSI Mini Maker Faire. Re producing legs and Plastic dipping the tips for durability.

Hey Grasshogger,

Thanks for purchasing a kit! The v2 files are on our website, www.meped.io. We put the 3D STL and 2D DXF files up there. The parts were drawn in Inches so to convert them to Millimeters, the scale factor is 25.4. You were extremely close with your calculations!

It would be great to see what you come up with for the leg tips. I was thinking about using Tool Dip but haven't gotten around to testing it yet.

Hi! Nice job... What electronic do you use? Can I give Arduino Uno with Arduino Sensor Shield v5?

Hi! I would like to 3D print the parts, but when I import the STL file in Repetier Host, the dimensions of the whole object are only 29.55 x 25.61 x 0.32 mm.
Could you tell me by which factor I have to resize this? Or is it possible for you to upload every part as a seperate STL file?

Edit:
Never mind, I figured it out. It's exactly a factor 10.
