RC Skid loader (1:10 scale)

This 1:10 scale RC skid loader is actually much more than a toy. It serves as a test bed for automation control software in the company that I work for. I have done the 3D design, the electronics and software for the drive controller and all the printing as part of a "slacktime" project, to give all of us in our department something really cool to program on. That is why the model is big enough to hold a RaspberryPi Zero, which is the actual hardware platform that we will be testing our software on (and the 2800mAh 12V battery will give us enough battery capacity for hours of operation).

With 42 single plastic pieces (32 different pieces, some of them needed multiple times), and over 88 hours of total print time for all parts, I had to do almost all of the work in my spare time at home. I have put a lot of love into the details, that is why all four axis are guided by two ball bearings each, just like the axis for the arm.

Since this kind of skid loader (which tries to be as close as possible in all dimensions to a Caterpillar 226B3) has four wheels rather than tracks, I have used GT2 belts internally to give it all-wheel driving capabilities with only two motors. For driving I use 100rpm 12V DC motors, the arm and the shovel are controlled by RC servos. My homemade drive control software allows for very smooth acceleration from the DC motors, to give it a distinct scale look-and-feel.

All needed .stl files are uploaded and a photo documentation on each assembly step is now available, have a look a the file tab.

By the way, if you like the little street cone in the photo, feel free to print some for yourself:

Hope you will like it and I would be thrilled to see lots of makes here!

The license does not allow derivatives (remixes), as one of my designs in the past was “taken” from me to collect donations on Thingiverse via a “Remix”, that did not add any significant value. That made me really sad. If you want to seriously remix this design, please contact me and I will gladly approve that.
