1 Tuesday, October 1, 2013Woodlawn Advanced Robotics I Lesson 4 Woodlawn Advanced Robotics I: Lesson 4 In this Lesson 4 we will learn about: Remote Control Robot Remote Control Ambient Light Calibration Ambient Light Data Plot

2 Tuesday, October 1, 2013Woodlawn Advanced Robotics I Lesson 4 Review From Our previous classes: Sensors: measure the environment Actuators: affect the environment End Effectors: interact with the environment CPU: Central Processing Unit, a.k.a. the brains Infra Red Light: Invisible light with lower frequency Task: in the above pictures, circle a sensor, an actuator, an end effector, and infrared remote control.

3 Tuesday, October 1, 2013Woodlawn Advanced Robotics I Lesson 4 Program your Robot Task: program your robot to use the infrared sensor as control input. Task: do closed loop control using your brain as a CPU.

4 Tuesday, October 1, 2013Woodlawn Advanced Robotics I Lesson 4 Electromagnetic Spectrum Electromagnetic radiation: produced by different processes detected in different sensors. Electromagnetic radiation such as visible light and infrared radiation can be expressed in terms of energy, wavelength, or frequency.frequency

5 Tuesday, October 1, 2013Woodlawn Advanced Robotics I Lesson 4 Our First Program Program your robot to read the ambient light sensor Task: shine a light onto the ambient light sensor, record the sensor reading Task: repeat the above task with a different amount of light shining on the sensor. Task: read the time measurements and tabulate them below Task: program your robot with your desired top speed, and let it race! Measured Light Sensor OutputLight Intensity (qualitatively)
