Researchers developed a mixed-integer linear programming (MILP) framework to optimize dual-arm robotic strawberry harvesting in plant factories, minimizing total operation time by jointly scheduling stop positions and fruit assignments. This framework demonstrably reduced the number of stops and nearly doubled harvesting throughput in scenarios with balanced fruit distribution compared to unoptimized and single-arm approaches.
Key insights
- Optimal coordination of dual robot arms, particularly under balanced fruit distribution, significantly improves harvesting throughput by minimizing idle time and maximizing parallel operation.
- Pre-computing configuration space costs and optimizing robot arm installation poses are effective strategies for handling kinematic complexities and reducing computational overhead in harvesting planning.
- Integrating a 'stop-and-harvest' strategy with a MILP framework provides a robust method for efficient 'pick-and-collect' harvesting of delicate fruits in semi-structured plant factory environments.
