Course Home Syllabus Course Calendar Activities and Projects Building References Programming References Presentations Gallery Frameworks Additional Info	Challenge 1: Your robot must navigate the maze from (1) to (2) without crossing any lines, using dead reckoning ( distance and direction). Above: Taffrail log- nautical equivalent of a rotation sensor. More on navigation Alternate Activity: Haunted House How do we navigate on dry land? By using signs and waypoints. Challenge Part II: Navigate the maze using a color sensor and a series of switches in a loop( this is termed a polling algorithm) to read 'signs' indicating where to turn-for example If blue detected, turn right If green detected, turn left If red detected, stop If yellow detected-slow down Assignment Note that you can now set the robot anywhere on the course and it 'knows' where to go. Sample Program Video Example of student work Extra Credit/Extension: Fast Road follower- if green bear left, if blue bear right, if yellow turn right, if red stop etc. Video Train- show color ticket- drive to corresponding station Elevator- raise elevator to correct floor	Links Google Driverless Vehicles News Item: Self-Driving cars Google Car TED Talks: Self-Driving Cars Introduction to Sensors( pdf)
