Presentation Transcript

  1. A-Mazing Build your robot to drive out of any maze presented with

  2. Part One – Touch Sensor Maze • Use your touch sensor and measured movements to get your robot out of your “workstation maze” after touching 4 walls

  3. Requirements • Have your robot drive the red line (the blue lines are the outline of the cabinets) • Can drive in either a counterclockwise or clockwise direction • Speed not a requirement • Must start and finish outside the cabinets/boxes • Your robot must have a touch sensor attached to the front • Must touch four of the “blue” walls • Show your robot to instructor by Wednesday 11/16 NXT bucket NXT bucket

  4. Advanced students will . . . • Meet the requirements on or before the proposed due date • Two levels of advanced robotics • First Level: • A successful path that contains 7 touched walls AND starting and stopping on the exact same spot outside of the cabinets/boxes • Second Level: • Top 3 fastest time in completing the first level OR keeping your 7 touched walls path an exact distance from the wall by using an ultrasonic sensor

  5. Programming Hints Start driving forward a distance Turn 90⁰ Wait until you bump into something Stop your motors Back up slightly Turn 90 Loop 4 times Drive forward a distance Stop your motors Turn 90⁰ Drive forward a distance and stop

  6. Perseverance • Perseverance is the steady persistence (sticking to it) in a course of action, a purpose, - especially in spite of difficulties, obstacles, or discouragement. Effort is the main determinant of achievement – not innate ability Speed Counts. Faster = Smarter Care, perseverance and craftsmanship count

  7. Performance AssessmentBased on Group Performance Advanced (Level 4) • 100% - Level 3 completed on or before due date; top 3 speed in class OR ultrasonic sensor attached to keep same distance away from wall at all times • 93% - Level 3 completedon or before due date; 7 walls touched AND Started and Stopped on exact same spot Proficient (Level 3) • 85% - Touch Sensor Maze completed on or before due date; progress made toward achieving goal of Advanced (Level 4) butnot achieved • 80% - Touch Sensor Maze completed; little attempt at meeting Advanced (Level 4) Basic (Level 2) • 75% - Touch Sensor Maze completed but after posted due date Below Basic (Level 1) • 70% - Attempt made but not successful (robot was repeatedly tested but goal never met AND help from classmates searched out) • 60% - Attempt made but not successful (robot was tested once or twice, sustained attempts not made without teacher intervention OR teacher help was required to finish all aspects of assignment) Teacher can assign a final grade that falls between the percentage based on proximity to meeting a standard

  8. Habit of Mind AssessmentCare, Perseverence and Craftsmanship CountBased on Individual Performance Advanced (Level 4) • Is devoted to problem solving task • Evaluates work and produces exceptional results; focuses energy on accomplishing tasks with perfection • Always uses project time well; all conversations are on topic and held in a way that do not effect others; can explain cause and effect of actions Proficient (Level 3) • Sustains problem solving processes over time • Checks the quality of personal work; values accuracy and precision • Always uses classroom project time well. Most conversations are focused on the project and do not disrupt others; is aware of one’s actions and the effects of those actions on others Basic (Level 2) • Sporadically stays on task without prompting (stays in work area) • Is able to confirm that his/her finished product matches a criteria • Usually uses classroom project time well, but occasionally distracts others from their work Below Basic (Level 1) • Stays on task with prompting • Corrects work only when reminded; accepts direction in correcting work • Sometimes uses project time well but is often off task and disruptive to the work of others No Concept (Level 0) • Gives up on problem-solving task • Turns in sloppy, incomplete or uncorrected work; is impatient with details or restrictions; does not value accuracy and precision in work • Does not use project time well OR typically is disruptive to the work of others
