Heavy picker

Multipurpose waste sorting robot for bulky material

Heavy Picker is the strongest sorting robot that can easily separate multiple waste fractions with the help of various sensors, heavy-duty robot arms and artificial intelligence. It provides a simple, unmanned sorting process and makes waste sorting safer, more accurate and profitable.

Heavy Picker minimizes the need for pre-shredding waste or pre-sorting the waste with an excavator. The robots work completely autonomously, even around the clock. Click the icons below for more information.


Usual conveyor width 1800 mm.

Sensor unit

The sensor unit, including NIR hyper spectral imaging sensors, 3D sensor system, hi-res RGB camera, metal imaging sensor, VIS visual light spectrum sensor, scans the waste stream.


ZenBrain is our AI software that analyzes real-time sensor data and controls the robots.

Control Panel

Here you start and stop robots, open the cage door and move the robot arm.

Discharge Chutes

2 x 2 discharge chutes per robot arm.

Robot arm

A single robot arm makes up to 2000 picks/hour. Its working area is 1800 mm x 2000 mm.

Smart Gripper

The durable smart gripper is designed for waste. It is collision-proof and easy to maintain. It grips waste fractions of various shapes and sizes quickly and accurately.

Smart Motion Control

Traditionally robots follow fixed preprogrammed trajectories. In waste sorting robots need to pick complex objects from random locations on a moving conveyor and throw them to chutes. ZenRobotics’ smart motion control increase speed and improve robot durability as robots can better avoid collisions.
