Tonight I 3D Printed mounting brackets for the front wheels. I have acquired some cheap and simple testing wheels which will be used before I spend time and effort designing my own with proper bearings. My final wheels will also be more ball-like, so they want stuck as easy in terrain. Before doing the design I also want to test some different heights for the front wheels, with the first test wheels the robot will have a zero degree vertical angle. I want to test to use slightly bigger wheels and increase the vertical angle. If an vertical offset angle can increase the performance when cutting higher grass, meaning the cutting blade will trim the top of the grass stem at the vertical offset angle max degree and the min degree will cut the rest of the grass stem to the desired level. When the robot is up and running I will measure power consumption with different angles, check the cutting quality and compare how high grass the different angles can handle.

The 3D printed brackets came out great. Following the contours of the body and blended in quite good. This parts was also printed with PETG.

A quick and dirty assembly with all wheel mounted.

Saturday’s late night fun ended with playing around a bit. touchscreen, USB ports and external HDMI port for ease and ability to change and program on the fly when outdoors. what do you think?‬

A very quick and messy under the hood picture. This is not how it will or should look like. The final assembly will shine!
