Proposal of a two-tier autonomous campus waste collection system, Mothership
1 reports · 1 sources
Wei Wang et al. proposed a two-tier autonomous waste collection system, Mothership: an electric compaction garbage truck carries two low-speed sidewalk robots, RoboCarts, which retrieve and transport standard two-wheeled bins to the truck, return them to their original locations, and return to the truck to recharge. The study used discrete-event simulation to evaluate throughput under synthetic campus layouts with bin densities of 2-16 bins/ha: a two-cart configuration serves 20-29 bins/h; three to four carts require an 80 m wide docking radius to stay busy and can reach 35-49 bins/h at medium to high densities, so the optimal docking radius must be selected together with fleet size.

- Mothership: A Two-Tier Autonomous Refuse Collection System for Pedestrian Campuses
Mothership proposes a two-tier autonomous refuse collection system in which an electric compaction truck carries two low-speed sidewalk robots, RoboCarts, that fetch and deliver standard two-wheel bins to the truck, return them to their positions, and re-dock for charging. A discrete-event simulation over synthetic campus layouts at 2-16 bins/ha quantified throughput: a two-cart configuration serves 20-29 bins/h, while three to four carts can reach 35-49 bins/h at an 80 m docking radius; the optimal docking radius must be chosen together with fleet size.
