PROJECT TOPICAgri-Tech, Environment & Biotech
Soft-Gripper Fruit Harvester
A delicate manipulation robotics concept studying compliant elastomer fingers, pressure-limiting vacuum actuation, and stem-cutting blades designed to pluck fragile orchard produce.
Bruise-Free Delicate Produce Harvesting
- ✓Uses flexible elastomeric fingers that conform to irregular fruit shapes.
- ✓Regulates internal pneumatic finger pressure to prevent excessive surface pinching.
- ✓Integrates a miniature serrated rotary cutter to cleanly sever stems.
The Engineering Challenge
Problem / Objective
Rigid metal robotic grippers bruise fruit flesh, causing rapid rotting and disqualifying produce from commercial fresh retail.
