This 1:10 scale RC skid loader is actually much more than a toy. It will serve 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 it will give us enough battery capacity for hours of operation).
Using a RaspberryPi versus an Arduino Board will allow much more options with regard to camera and sensor based autonomous driving, cloud connection, and other IT minded features.
With 41 single plastic pieces, and over 70 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.
The model is almost done, I will start to upload 3D-print files within the next days, together with some photographs of the real model, of which the last parts are still printing as I type this. As a little teaser, I have already uploaded the files for the rims and the tires.
Of course I will disclose also the electronics description (with respective firmware).
Hope you will like what is about to come very soon!
