Canadian 3D-robotics supply chain company Attabotics, has raised $50 million in a Series C funding round.

The investment was led by Ontario Teachers’ Pension Plan Board (Ontario Teachers’) through its Teachers’ Innovation Platform (TIP), along with existing investor Honeywell.

Attabotics has raised $82.7 million to date.

What is 3-D supply chain robotics? Attabotics says, inspired by ant colonies, it works on condensing a traditional warehouse into a single, vertical storage structure. Inside this structure, a robotic shuttles move in three-dimensional space (X, Y, and Z axes) to store and deliver goods to workers.

Attabotics says its single structure reduces a retailer’s warehouse footprint (by up to 85%), allowing them to place warehouses closer to cities.
