Functional Requirements for Mapping an Area

Functional Requirements for Mapping an Area External and/or internal reference systems Movement and tracking orientation Coordinates, boundaries, and object mapping

Positioning and Calibrating Distance Sensors Sensor mounting and positioning Why calibrate sensors? Methods for calibrating sensors and filtering

Measurement calibration and filtering

Calibrating Wheel Movements

Calibrating Wheel Movements Why calibrate linear movements? Provides awareness and control Enables faster movements Why calibrate angular movements? Helps the robot to keep track of its orientation Speeds up the process of verifying orientation Speeds up the process of turning to face a direction

Calibrated moves and rotations

Coordinates and Object Detection

Coordinates and Object Detection Select a local point of reference Choose a coordinate system Align to the axes of your coordinate system Map the area and object coordinates Detecting new objects

It is alive!

Review We discussed coordinate systems and requirements for mapping We talked about positioning sensors and the types of errors that sensor readings can include. We showed you how to calibrate a sensor and how to calibrate DC gearmotors so that we get consistent linear and angular movements We finished up with a demonstration of our MSGuard-Bot mapping an area and then detecting and deactivating our MSBug-Bot when we added it to the area.
