Waste Bot
Collects animal waste.
Collects animal waste within 18 tiles of its station: 
3 fertilizer a pile, counted as soon as it's picked up. It carries 1 pile (up to 5 with upgrades) per trip to the nearest Fertilizer Facility. After 5 trips it goes home to recharge.
Recharging takes 16 seconds at its station and costs biofuel: 1, plus 1 for each capacity upgrade and for every second speed upgrade. Speed upgrades take it from 1 to 2.6 tiles a second. Each upgrade costs more than the last, counted across all bots of its kind. Demolishing one takes its upgrades back off that count, so the next upgrade costs less.
