# 140 - Control Unit
The need for control in MVP 0.1:
- speed of four wheel motors
- central hub motor
- battery level tracking (optional)
WiFi reception and user interface.
Need for control (MVP 0.2):
- grabber arm motors/hydraulics
# Ideas
The device could provide its own WiFi hot spot, and a browser interface + REST API. Access control by username, pw (i.e. no need to connect it to Internet when running a demo).
# Specs
Weather capability of -20..+40°C.
Enclosure that is weather proof (rain is okay, but won't be immersed in water). I.e. cable pull-throughs. Sounds like Etola boxes. 😉
If there is no active signal to the controller, the vehicle needs to get to stand-still (i.e. there's some kind of timer that gets reset by a REST API call).
Before going too much into software, that deserves its own repo.
