1. ROBOTIC GUIDANCE Joe Stawicki

2. PROJECT DESCRIPTION  Teach a robot to guide a person to a predefined destination.  The robot must use a cam and a vision algorithm(s) as the main guidance.  Sensors such as bump, infra-red and ultra-sound could provide direction and safety for the robot.  The solution should be easily modified for alternative routes.  Check out Alexander Popov’s 2011 senior project for techniques about driving the robot.

3. MY SOLUTION  Turtlebot  Kinect Sensor/Gyroscope  ROS (Robot Operating System)  Moves the robot  Gathers data  Kinect Sensor  Gyroscope  Calculates the next position  User Interface  SLAM (Simultaneous Localization and Mapping)

4. KINECT SENSOR  Variety of Sensors  3D depth sensors  Laser  RGB camera  Array of Microphones

5. SLAM  Simultaneous Localization and Mapping  Build map of unknown environment  Uses Sensors  Keeps track of current location  Based on what it sees/has seen  Navigate to a particular spot on the map

9. PROBLEMS  Network Issues (SNC Firewall)  Using ROS (Open Source)  Weight Balance Issues

10. MORE WORK…  Calibration of the gyroscope

11. METHODOLOGY  Moving the Robot using Sasha’s project  Assembling the Turtlebot  ROS Installation  ROS Tutorials  Teleop/Navigation  Adaptation to new environments  Documentation
