Requirements

The following requirements regarding task performance, safety and sofware should be satisfied by the simulated PICO robot:

• Task performance
  • The robot must be able to recognize target cabinets
  • The robot is capable of planning a path and is able to adapt to unexpected circumstances, for instance a closed door.
  • PICO can rotate in place, in order to re-position when in front of a cabinet
  • Must be able to announce the completion of the current objective
  • The robot should not be inactive for more than 25 seconds.
  • The robot has to be able to detect static and dynamic object and present them in the world model.
• Safety
  • The robot avoids bumping into walls and doors
  • The robot avoids collisions with static and dynamic obstacles
  • PICO must obey the limits on translation and rotation velocity
  • PICO should maintain a 5cm Stopping distance from the obstacle.
• Software
  • The software is started by a single executable
  • The software can be easily updated .
  • The User-interaction should be minimal and User-friendly.

Functions

Input data processing

• Laser range finder interpretation

Inputs: distance and angle from LaserData Interpreting data generated by the laser range finder, using a 2D SLAM algorithm.

• Odometer interpretation

Inputs: OdometryData Calculates speed of the mobile robot integrating position values, relays the data to the SLAM algorithm.

• Sensor Fusion

Combining sensory information from multiple sensors can have uncertainty.This module can help to have reliable information flow to correlate and deconstruct data.

• Vector map data interpretation

A function used for structuring data obtained from the provided map of the testing area. To be used as inputs for position estimation and path planning functions.
