System shall have sensors to sense and map the environment #11

Closed alextmeyer closed 10 years ago

alextmeyer commented 10 years ago

Description: Choose sensors that will enable the UAV to autonomously "see" all aspects of the environment. Probably a combination of multiple sensors. Capable of sensing a changing environment. Ability to work indoor and outdoor. Chose Laser Range Finder, IMU, and Kinect

Person Responsible: Whole team

Dependencies: Structural team (lift capacity), Human Sensing Team (Kinect)

Fit Criterion: Weight that is less than lift capacity given to Nav/Map team. Sense environment completely. Have to consider error and accuracy of sensors.

Supporting Materials: Intro to Autonomous Mobile Robotics book
