I’m working on making robots to collect bottles and redeem the California refund value. Basically so you could bring your bottles to a big mechanical sorter, dump your bottles in, and get maybe like 2c per bottle paid to you, then 3c pays for the cost of transport. Currently based out of Mountain View. My background is in machine learning and I’m muddling through the electronics and mechanics, would definitely like to have help with that stuff or really just find other people interested in this intersection.
