FAST FACTS
The ARCi robot is a semi-autonomous machine used as a carrying platform.
Being modular, it can be adapted for different uses, including pest and disease management.
The robot is in the pre-commercial stage of development.
Michael Back and his son Simon, owners of the Backsberg wine estate between Paarl and Franschhoek in the Western Cape, had a problem at blueberry harvest time: their pickers were having to walk up to 150m to and from quality-control centers to deliver the fruit. The inefficiency of the system was obvious, so the Backs set out to find a way of reducing walking time and increasing the hours dedicated to picking and sorting.
Simon explains that they didn’t want to use tractors, as their orchard rows are narrow (2m to 2,5m depending on the variety), and tractors would have to move past farmworkers, whose numbers grow to over 300 in peak season from August to November.
Aside from this, tractors are heavy on fuel, have a high carbon footprint, increase the risk of compaction, and require drivers.
“We were looking for a conveyer-like solution onto which workers could place their buckets [of fruit] right where they were working. My father then came up with the idea of having a robotic carrier platform that automatically followed picking teams up and down rows to collect and deliver their buckets to the quality-control centers,” says Simon.
