Let’s Begin Meet and Greet – Camp leaders introduce themselves – Students introduce themselves
Overview of Workshop More Robotics Application of Robotics Computer Science Review of Knowledge
Let’s Talk Robots Review from summer Robotics Camp – Overview of robots – Review logic and applying logic to computer science – Discuss input and output – Explore robot parts and how those parts are used – Experiment with MindStorm Software and components
Robot Components Your definition of a robot How does a robot operate – What components does a robot need to operate Reason for robots – Help Humans Handle hazardous tasks Perform repetitive tasks
Input, Output, Operation Conventional Input – Keyboard, Mouse – Microphone, Camera Robotic Input – Sensors Push button Ultrasonic Color
Input, Output, Operation Operation – Think arithmetic! Cognitive thinking (Use brain to solve problems) Decision making Problem solving Manual operation – Write problems down on paper and try to solve Automatic operation – Calculator our robot – Enter calculation and provides annswer
Input, Output, Operation Robots really are computers themselves – Robots think input, output, and operation Humans are the same – Think input, output, and operation
Summary Short recap – Robot performs complex tasks – Robots need a power source and central controller – Use sensors to gather information – Thinks input, output, and operation – Legs, arms, and wheels for movement
MindStorm Let’s open MindStorm kits and identify the parts
Identify Software Features Motion Features – Active Port – Power – Direction – Duration Rotation Degrees Time – Steering – Brake or coast modes
Ports What are ports? – Cables connecting brain to components. A, B, C – Used for controlling motors. – Input picture here 1,2,3,4 – Used for connect to the sensors. – Input picture here – We will learn more about these later.
Control The Direction Dragging the arrow left/right changes the direction that the robot will move. – This feature is only active when two motors are selected. It controls forward, backward, or stop.
Duration Of Activity Duration effects how long the block is active. Types of Duration – Degrees – Unlimited – Time – Rotation
Programming: Switch Statement Switch Statements are for making decision For example, we might want to move forward if the button is pressed, and move backwards if not.
Switch Statement Here we have a loop with a switch statement inside. You drag actions inside the switch statement. The Move Action on top is what to do if the button is pressed. The Move Action on the bottom is what happens if the button is not pressed
Review Robot Input – Touch Sensor Pressed Released Bumped – Color Sensor ROYGBIV Light or Dark – Ultrasonic Sensor Determining Distance Near or Far Programming Inputs – Wires
Review Robot Output – Display Text Picture – Sounds – Color lamp – Motors Programming Block Output – Wires
Review Motion – How does power of the motors affect the bot? Distance Speed Steering – How do we steer? By rotating one motor faster than the other. How do we turn sharper?
Review Rotation – Three types of rotation Degrees Rotations Time 1 Rotation is equivalent to 360 degrees. – How many degrees would be in 3 rotations? Time Infinite Seconds
Review Operation – Loop Repetition Unlimited Limited – Switch Logic True or False If this then that, Or else this then that
