Project:

GNSS RTK-Based Robotic Lawnmower

Location:

Lebanon, Indiana, United States (2007-2008)

Purpose:

Auto-steering of lawn mower with cm level accuracy

Configuration:

1 reference GNSS station, 1 GNSS rover, 1 auto-steering control system

Communications:

UHF serial communications

Details:

Under purely robotic control, the lawn mower wanders off course due to errors caused by wheel slippage, uneven terrain, and other mechanically-induced errors. GNT’s GNSS RTK (Real-Time Kinematic) navigation solutions and attitude information were used to support the development of a prototype robotic lawn mower control system.
