I decided to share the unmanned ground vehicle project I made to improve myself by publishing all the design files and material list.
The design process took 1 week, printing time 1 week (with 2 printers and 0.6mm nozzles). It is very pleasant to assemble and drive, powerful, durable, fast and enjoyable.
Effortless as the number of parts to be printed is low. You can redesign the vehicle for different purposes by making changes on the design files and
You can use it autonomously or by image processing with raspbery pi.
The vehicle has a total weight of 3.3kg. 330*340(with tires)
