1. A-Tech Technical Training

2. Robotic Design - Basket Grey pieces act like funnel Black rubberband keeps basket closed

3. Robotic Design – Manual Control Fast adjustment to basket vertical position

4. Robotic Design - Bumper Yellow claws are adjustable Goes up and down

5. Robotic Design – Counter Weight Keep robot form tilting forward

6. Robotic Design – Rear Wheel Single wheel design let robot turn easily and accurately Can turn forward and backward very fast

7. Robotic Design – Gear Box Use 3 circular gears to open and close basket Gears are 1 to 1 ratio Use linear gear to raise basket up and down One motor can control open / close and up / down

8. Robotic Design – Structure Lots of braces to keep robot solid

9. Robotic Design – Sensors/Motors Use 2 light sensors 1 ultrasonice sensor 3 NXT Motors

10. Robotic Design – Light Sensor Sense shades of colors How does it work? How does calibration work? How fast is it? 35 60 0 100

11. Robotic Design – Utrasonic Sensor Sense Distance How does it work? What is the minimun distance? How fast is it? 3 – 4 Inches Min.

12. Software Design – Detecting Distance Set motor to unlimited move forward Set sensor until < distance ( in centimeters or inches ) How many centimeters in an inch? 2.54 cms

13. Software Design – Line Following Algorithm C B C Motor Speed stay constant B Motor Speed slower or faster than C motor, never same

14. Software Design – Reference Robot This makes sure our robot is starting from the same position and angle at each time 3 2
