Description
Planning and Control for the Darpa Urban Challenge by Yoshi Kuwata, Chun Sang Teo
and Gaston Fiore
The
2007 Darpa Grand Challenge
is the third in a series of competitions organized by
DARPA to accelerate research and development of unmanned
robotic vehicles capable of performing military supply missions. The 2007 DGC
is the first such competition that requires the vehicles to navigate an urban
environment. Some challenges arising from such a setting include the
requirements to: i) avoid both static and moving vehicles/obstacles, ii) plan
feasible trajectories in real-time, iii) obey rules of the road, iv) plan
trajectories that perform 3 point turns, parking in potentially highly
constrained parking spots, etc.
Team MIT
participated in the 2007 DGC and was placed
fourth among six teams that completed the race on November 3rd, 2007. ACL
faculty and students were involved in the design and development of the
Rapidly-exploring Random Tree (RRT) based motion planner and vehicle
controller. Our approach is unique in that a single unified planner was used,
whether operating in a highly constrained structured lane following
scenario or in the unstructured parking lot scenario (which necessitates a highly
exploratory planning approach).
