Navlab
Navlab is a series of autonomous and semi-autonomous vehicles developed by teams from The Robotics Institute at the School of Computer Science, Carnegie Mellon University. Later models were produced under a new department created specifically for the research called the "The Carnegie Mellon University Navigation Laboratory".[1]
History
Research on computer controlled vehicles began at Carnegie Mellon in 1984[1] and production of the first vehicle, Navlab 1, began in 1986.[2]
Applications
The vehicles in the Navlab series have been designed for varying purposes, "... off-road scouting; automated highways; run-off-road collision prevention; and driver assistance for maneuvering in crowded city environments. Our current work involves pedestrian detection, surround sensing, and short range sensing for vehicle control."[3]
Several types of vehicles have been developed, including "... robot cars, vans, SUVs, and buses."[1]
Vehicles
The institute has made vehicles with the designations Navlab 1 through 11.[3] The vehicles were mainly semi-autonomous, though some were fully autonomous and required no human input.[3]
Navlab 1 was built in 1986 using a Chevrolet panel van.[2] The van had 5 racks of computer hardware, including 3 Sun workstations, video hardware and GPS receiver, and a Warp supercomputer.[2] The vehicle suffered from software limitations and was not fully functional until the late 80s, when it achieved its top speed of 20 mph (32 km/h).[2]
Navlab 2 was built in 1990 using a US Army HMMWV.[2] Computer power was uprated for this new vehicle with three Sparc 10 computers, "for high level data processing", and two 68000-based computers "used for low level control".[2] The Hummer was capable of driving both off- or on-road. When driving over rough terrain, its speed was limited with a top speed of 6 mph (9.7 km/h). When Navlab 2 was driven on-road it could achieve as high as 70 mph (110 km/h)[2]
Navlab 1 and 2 were semi-autonomous and used "... steering wheel and drive shaft encoders and an expensive inertial navigation system for position estimation."[2]
Navlab 5 was inducted into the Class of 2008 Inductees to the Robot Hall of Fame, though it was announced in 2007.[4]
