Israel Aerospace Industries (IAI) Lahav Division is continuing studies
with aircraft manufacturer Airbus on the development of a semi-robotic
towbarless tractor called the TaxiBot Dispatch Towing System.

Major components of the TaxiBot concept include a towbarless FMC
Technologies (now JBT AeroTech) PTS-1 tug equipped with a unique
mechanical interface to the nose landing gear; a low-level control
function for driving the vehicle; and a vehicle electronics system
that provides high-level control for managing towing operations while
in pilot-control mode.
