UGV - large mower, modular design

Hello, I am building a large mower/UGV. It is designed to be fully modular.

The RC version is almost finished, see YouTube video:
RC version tested indoor because of winter here
The mower deck can be added within a minute (4 screws) so I can use it for other tasks very easily like transportation, snow plow, pesticides sprayer,…
Goals:

  • vehicle for large properties
  • modular design
  • I might make as an open-source project of it with all steps to rebuild if others are interested
  • using only parts which are online available (no old things laying around in the shed)
  • easy to build as possible (most difficult part is welding)
  • easy to maintenance (e.g. good wiring, connectors,…)
  • autonomous mode for mowing and RC
  • optional seat
  • fully electric
  • enough battery space
  • camera, WiFi

For mower deck I am using an 51cm electric mower with 80V system. I connected it to a large e-bike controller and a step-up converter.
I am using Wifi Halo so I have good internet connection for camera, and on-board computer. I tested it already in 200m distance with trees in line of sight.
The electronics for RC version of main body including camera and WiFi is trivial to build up (no soldering needed and totally beginner friendly). The mower deck electric transition is more difficult.

Now am planning GPS-RTK. My current favorite setup would be Orange Cube+Hero4+Mini Carrier Board. I want to place it at top of antenna mast so there is 50cm distance to the 24V cables and around 80cm to the electric motors avoiding any interferences. I am digging to the threads here on this topic. I am an advanced programmer but those flight controllers are totally new for me. So I appreciate any suggestions.

Cool! do you have a link for those wheels?

I bought it as a set:

This simplified things significantly, allowing me to focus on other tasks. :slight_smile:
