Geoffrey Hollinger, Oregon State University, USA: Bin-Dog: A Self-Propelled Platform for Bin Management in Orchards
Bin management during apple harvest season is an important activity for orchards. Typically, bin management is conducted by tractor-mounted forklifts or bin trailers. Before harvesting, tractor drivers need to estimate the number of bins required and place empty bins between tree rows accordingly. However, due to difficulty in the estimation, drivers still need to frequently replace full bins between tree rows with empty bins so pickers can pick apples continuously. In order to simplify this work process and improve work efficiency of bin management, we propose the concept of a self-propelled “bin-dog” system. This system was designed with a “go-over-the-bin” feature, which allows it to drive over bins between tree rows. To validate this system concept, a prototype was designed and built. Field tests in a commercial orchard showed that when a full bin was placed 50 m away from the entrance of a lane, the prototype system could replace a full bin with an empty bin in 354 s. Simulated trials with multiple vehicles in the orchard environment show potential time savings of up to 30% versus conventional bin-management methods.
