Tomato pruning robots are limited by the absence of accurate shear simulation models for tomato stems. Conventional homogeneous discrete element models are incapable of characterizing the multi-layer heterogeneous structure of tomato stems, which gives rise to significant simulation deviations. With Zheza No. 8 tomato...
Agricultural manipulators are vulnerable to disturbances induced by compliant and hard contact, variations in object stiffness, and sudden constraint release during branch severing in fruit harvesting and pruning. External force/torque sensors, however, are costly, difficult to install, and poorly suited to agricultura...

Labor shortages and the push for higher greenhouse efficiency have accelerated interest in automated harvesting. However, the development of a universal harvesting robot has been constrained by large variations in crop architecture, especially plant height. In this review, a height-based stratification of greenhouse ha...
