After sourcing the motors from eBay, I started to think about the basic features “The Robot” will have, and quickly started to make up a wish list of parts.
The featured image above is only inspiration for my own design, alluded to in my swag design
I want “The Robot” to be social and robust. Not only can it do heavy duty work outdoors, but I’ll build in the capabilities to interact with social media via live streaming and post updates. This means it will need an internet connection, and I have plans for cellular integration.
If I want “The Robot” to be autonomous, it will need to know where it is, and GPS is the obvious solution (in combination with proximity sensors). By plotting a perimeter via GPS coordinates, “The Robot” will have its own invisible fence! Simply introducing the GPS feature leads to a need for a GUI (Graphical User Interface) or Web interface. “The Robot” will host its on web server and LAMP Stack development suite via Raspberry Pi 3 with 200GB of Hard Drive space and a Dynamic DNS service – implemented only at run time. Developing a simple REST/Cloud service will allow mobile integration and realtime telemetry.
So, basically “The Robot” will send awesome information to my phone while its running, along with a First Person Video feed (via a UDP/Python connection and 5.8GHz transmission) and other awesome stuff.
This is a rough list of parts:
- Sabertooth Dual 25-50A Motor Controller
- 24v Geared motors – high rpm (wheelchair)
- Raspberry Pi 3
- GPS/Cellular adapter Rpi
- 200 gb SD micro
- USB camera
- RC Receiver
- Rubber Tank track – from Stump remover
- Beacon Light – white or amber
- 4″ linear actuators x3
- 12v 33ah sla battery x2
- 10w led lamp x2
- Digital Energy Display
- 3mm led pre-wired 12v
- 24v panel indicator lamp – red, blue, amber
- Arduino Mega
- Hardware and tools
