Give specific examples of a robot and the type of movement or sensors it will need. Created by Emily RCG Williams for the South Pasadena Education Foundation 11 Movement Define Types of movement: Locomotion – The ability to move from place to place (move from place to place) Localization – To perform functions in a specific area (turn head) Manipulation – To touch or move by mechanical means (move other things around) Cooperation - To work together (two motors working together for movement) Created by Emily RCG Williams for the South Pasadena Education Foundation 12 Day 3 - Agenda Reflection discussion Definitions of types of movement Watch “Robo Cup Dog Soccer” identify each type of movement Finish Drive Forward Challenge Start Bump and Run Challenge Created by Emily RCG Williams for the South Pasadena Education Foundation 13 Drive Forward Challenge 1.

Bump & Run Races Have groups which complete this extend the program by putting a ‘Forever’ loop around the previous program to make the robot continuously go back and forth between two walls. Created by Emily RCG Williams for the South Pasadena Education Foundation 15 Day 4 - Reflection In real life why is it important to be specific when giving directions? Write down the step by step directions of how to fold a paper airplane. Created by Emily RCG Williams for the South Pasadena Education Foundation 16 What do we need the robot to do? Moving: The robot must be able to control some set of actuators to move how and when we want it to. We must be able to reliably place the robot anywhere we want. Sensing: The robot must be able to perceive its environment through sensors locate obstacles to avoid, and objects of interest that we want it to interact with. Plan/Act: The robot must be able to make decisions using its processor based on it’s sensors and feed them to it’s actuators to be able to move. Created by Emily RCG Williams for the South Pasadena Education Foundation 17 What is a sensor? Takes readings from physical environment and turns it into an electrical message/signal Sensors we will work with: Touch- hit something and it react Light- can sort by color or detect light from dark Sonar/ultrasonic- tells how far away things are Sound- tells how loud something is Created by Emily RCG Williams for the South Pasadena Education Foundation 18 What is a processor? It is the logic circuitry that responds to and processes the basic instructions that drive a computer. A computer needs to be able to: Receive inputs from the sensors, and convert the sensor readings into perceptions Make decisions based on it’s perceptions Created by Emily RCG Williams for the South Pasadena Education Foundation 19 What is a processor? Continued Use these decisions to change its environment (or move itself in the environment) using its actuators. Each of the previous three things is programmed by the user using a programming language. Takes readings from physical environment and turns it into an electrical message/signal Touch- hit something and it react Created by Emily RCG Williams for the South Pasadena Education Foundation 20 What is an actuator? Takes electrical message and turns it into a physical action. For example: Electric motors receive electricity which makes their axles turn. These can be connected to wheels, which can make the robot move Pumps receive electricity which makes them compress liquid through tubes which can make a robotic arm move around. This arm can push, pull, and lift things in the world.

Created by Emily RCG Williams for the South Pasadena Education Foundation 27 Day 5 - Agenda Article Discussion/Reflection Finish Challenges Go Forward Bump and Run Detect and Run Begin building and programming for maze completion Created by Emily RCG Williams for the South Pasadena Education Foundation 28 Ultra Sonic Sensor Ultra Sonic sensor sends out a high frequency chirp from one circle and the sound wave bounces off an object and returns to the microphone in the other circle. Because sound travels at a constant speed ~1,125 ft/s the processor can calculate the distance the sensor is from an object and respond based on the programming. Created by Emily RCG Williams for the South Pasadena Education Foundation 29 Ultra Sonic Sensor In what situations might an Ultra Sonic sensor fail?
