Autonomous Forestry Fleets

harvesters · forwarders · drones · fire

In the forest, autonomy has reached the crane but not the wheels. Harvesters automate the boom with an operator in the cab, and drones do the work no machine can drive to.

The forestry task chain and how far autonomy reaches: survey with lidar mapping drones such as DJI is commercial; felling and processing with Ponsse, Komatsu Forest and John Deere harvesters uses boom automation with an operator, commercial; forwarding logs with autonomous forwarders is at research and trial stage; steep-slope logging uses tethered winch-assist machines with an operator on board; replanting with Mast Reforestation seed drones is early commercial; fire response with Rain's helicopter autonomy and DJI patrol drones is in early deployment.

Finding

Forestry machines automate the crane before the drive, because the forest floor is too uneven and varied for driverless travel

The cut-to-length harvesters and forwarders built by Ponsse in Finland, Komatsu Forest in Sweden and John Deere in Finland now move their booms under computer control: John Deere's Intelligent Boom Control and comparable Ponsse and Komatsu systems let the operator point the head while software coordinates the joints. Driving between trees on soft, rocky, sloped ground is still done by a person.

Autonomous forwarders, which carry cut logs to the roadside over a route the harvester has already opened, are the next step and are being tested in Nordic research programs. On slopes too steep for wheels alone, tethered winch-assist machines from makers such as Ecoforst and HAAS let harvesters work in the Pacific Northwest and New Zealand with the operator still on board.

Drones handle the rest. DJI and other makers' lidar drones map stands and count trees, Mast Reforestation (formerly DroneSeed) replants burned areas by drone, and Rain is building autonomy for firefighting helicopters with Sikorsky. Electrification is early: battery-electric and hybrid forwarder prototypes exist, but full-size machines work days from grid power. See Electric Forestry Equipment.
