Technology

Engineered for fresh-market fruit

Four SCARA arms, AI ripeness vision and a soft hybrid gripper treat every berry like a hand-picked one.

🦾

Four SCARA arms

Two manipulators per side on vertical carriages pick from two rows simultaneously.

🧠

AI ripeness vision

Deep-learning detection finds every ripe berry and skips green ones — fresh-market quality, every pass.

>97% ripeness accuracy · depth cameras + LiDAR + RTK-GPS
🫐

Gentle hybrid gripper

Silicone fingers with vacuum assist hold each berry with under 2 N of force. No bruising, no drops.

All-day autonomy

LiFePO4 power with a 600 W solar roof keeps the robot working through a full shift. Hot-swap batteries.

48 V LiFePO4 · tracked chassis for soft soil · 450 kg
