Building The Pathfinder Rover February 2012
This winning design from the 2011 Digilent Design Contest explores the idea of creating a versatile, minimalist, and low cost platform that can replace humans in hostile environments.
Microcontroller boards aren’t really available in Cracker Jack boxes — at least, not yet. However, they’re cheap enough now where I consider them not worth repurposing — that is, they’re disposable. Take the popular Arduino, Raspberry Pi (strictly speaking, a microprocessor board) and, say, the Wi-Fi enabled NodeMCU. They’re all available for $5-$10 in single-unit volumes. At those prices, it’s not worth spending an hour unsoldering and disconnecting prototype circuits.
