My old but still working Yardforce lawn mower roboter had increasingly problems detecting obstacles like trees etc. Its wheels just continued to turn head on the obstacle, digging itself into the gorund. A look at the wheels reveiled that the “spikes” were worn out and some even broken. So I decided to design replacement wheels with an improved profile.
These replacement wheels have a more gear like profile and feature about 1cm more width. My first test runs showed positive results- all obstacles were just touched and recognized porperly, although the soil is still pretty wet and muddy in this season.
Printing Instructions
Easy to print: print with the visual side facing the print bed. Use support only for the hole in the middle (grid support will do just fine)- remove support at the edges of the wheel if it is automatically suggested. I used 8% gyroid infill. For stability I printed the wheel with a 0.6mm nozzle and 3 perimiters, 4 bottom and top layers.
For my test run I printed the wheels in PLA but I think I will reprint them using a more UV light tolerable material like ASA later this year.
