Think of this project as a mini-version of the sadly quiet 'Oppy,' the Mars Opportunity Rover.
What I want to create is a solar powered buggy -- on a smaller scale -- that runs around when it gets sunshine, then shuts down when the battery runs low. As with it's Mars-based counterparts, I would expect it to shepherd its resources when power is depressed, but it would be great if it charged an onboard battery well enough to keep an arduino powered up even through the night, so that it could respond to radio pings.
And, biggest ask of all, it would also be great -- in fact, required -- that it be able to withstand a full shutdown, but still get back on its feet again once it had collected enough sunshine to power up.
Has someone done something similar enough to get me started on the right path? Thanks.
