2. Using Robotics to Teach/Learn Applied Math and Science Mathematics Programming Sensor Feedback Geometry Electronics Mechanical Engineering Measurement Simple Machines Ratios & Proportions Computer Science Mechanics Physics

3. Why Robotics? l Robotics is exciting, motivating, and fun! l Robotics connects students to advanced scientific research and development l Students learn by doing l You need to know a lot of math and science to design, build, program, and evaluate a robot

4. DPS Secondary Science Institute 4 Robocup l The Goal: By the year 2050, develop a team of fully autonomous humanoid robots that can win against the human world soccer champion team

5. DPS Secondary Science Institute 5 Outreach l How can we use robots to inspire middle and high school students? l What about the Digital Divide? l Is service learning a good model for enrichment programs? l RoboCupJunior: International, national, and regional competitions for elementary, middle, and high school students

6. Robot Software RoboLab uses icons to build a program. These icons turn on the robot’s motors. This icon makes the robot drive for 6 seconds. This icon makes the robot stop.

7. DPS Secondary Science Institute 7 The RCX l Hitachi H8/3297 series processor l 3 inputs/sensors (1, 2, 3) l 3 outputs/motors (A, B, C) l 32k RAM/ 16k ROM l Multiple threads of execution l LCD Display & Speaker l 3 programmable buttons l IR send/receive l Sensors ä Light, touch, rotation ä Sonar and compass avail

8. DPS Secondary Science Institute 8 LEGO Mindstorms NXT l Atmel 32-bit ARM processor l 4 inputs/sensors (1, 2, 3, 4) l 3 outputs/motors (A, B, C) l 256 KB Flash Memory l 64 KB RAM l USB 2.0 Communication l 4 programmable buttons l 100x64 b/w LCD Display l Sensors ä Active: Old light and rotation ä Passive Touch, sensors for NXT ä Digital Ultrasonic l Motors ä 170 RPM ä 360 RPM for old motors, why?

9. DPS Secondary Science Institute 9 ROBOLAB l Pilot Mode ä graphics based ä limited capability ä great for kids? l Inventor Mode ä variables ä conditionals ä loops ä multitasking l Investigator Mode ä Charts & graphs ä Analyze data

10. DPS Secondary Science Institute 10 Inventor

11. DPS Secondary Science Institute 11 Pilot

12. DPS Secondary Science Institute 12 Challenges 1. Getting there ä Using Pilot 1 - program your car to move for 1 sec ä Measure the distance it went ä Predict distance for n sec (Pilot 2 may be useful) ä Run and check model 2. Touch-activated ä Using Pilot 4 make it so your robot starts when the touch sensor is pressed and stops when it hits something ä How would you make it bounce off the wall and explore an area? ä How could you keep your robot from running off the table with a light sensor?

13. DPS Secondary Science Institute 13 Line follower l Design a program that can follow a black line l Questions: ä What sensors would your robot need? ä What simple algorithm could you use? ä How would you calibrate your readings? ä How would you test your robot?
