Your vehicle should be placed on the track and activated. It should remain motionless until a voice command (loud noise) is given. If your kit does not include a sound sensor, you may use any other sensor or a Bluetooth Connection from your phone. From this point in time, it has 1 minute and 30 seconds to complete the track and come to rest. Every 5 seconds beyond this will cost penalty points. A full sized PDF of the track and the 7 possible barcodes (values 0-7) are included on eCampus, as well as a few other possibly useful files.
39 Deliverables Your laboratory notebook should include a section for this subtask. It will be collected at the start of the subtask. Make sure that it is saved in PDF format. There will be a submission box on eCampus. Subtask scoring: The grading criteria are explicitly: • Start on voice command or other acceptable input + 3 points • Complete first turn + 4 points • Complete second turn + 4 points • Find black line on other side of first dowel + 10 points • Find black line of other side of second dowel + 15 points • Complete third turn + 10 points • Complete fourth turn + 10 points • Complete fifth turn (the U turn) + 10 points • Stop within dashed lines + 15 points • Beep the correct number of times + 15 points • Complete sixth turn + 4 points • Stop at red line + 10 points • Maximum possible score for this task 110 points Scoring Notes Five Penalty points will be assessed for every portion of 5 seconds in excess of 1½ minutes your vehicle takes to come to rest at (or pass – if it does not stop) the red line. Every time you must manually adjust the vehicle you will be assessed a 5-point penalty. (Exception, if you fail to stop between the dashed lines, you cannot move it between them and still get those points.) If you adjust it past a particular maneuver you will not get points for that maneuver, if you put it back before the maneuver you can still pick up those points, if it successfully completes the maneuver. Note that you will not get any time back for this. Penalty points cannot reduce your score on the demo portion to less than 40 points.
