Activity 1 – Page 15 Yes Robots are machines that can be programmed by computer and can do different things. Robots can be automatic, or they can be computer-controlled. Yes No No

Activity 2 – Page 16 What can a robot be used for in everyday life?

How robots work? Input (sensors) Control System (brain) Output (actuator)

Think & Share input 2 6 4 10 8 34 32 process output

How robots work? Input (sensors) Book Activity P-17 Sensors are used to tell a robot about its surroundings. Light sensor / detects light Sound sensor / detects sound Ultrasonic sensor / detects distance Touch sensor / touch and operate Temperature sensor / detects temperature Humidity / detects moisture surroundings Sensors: Parts tells the robot about its surroundings. Book Activity P-17

How robots work? Control System (brain) Control System: device that manages / controls the behavior of other systems. It acts as the ‘brain’ in any robotic system. It does all the processing for the robot. Processes are actions based on the input

How robots work? Output (actuator) An actuator is the part of the robot that performs a physical action. Output is the result you get based on your input and processing.

Edison Robot Activity 4 – Page 20 Look at Edison. What can you see ? What parts can you identify ?

Edison Robot

Microcontroller The microcontroller: is the main control unit of any automatic system or device. These systems and devices have an input unit for collecting signals or sensing the signals from an environment A control unit for processing the received signals An output unit for sending out signals or controlling an output device.

Programming Software Program : set of commands / instructions to solve a problem Edison Robot can be programmed using : - visual programming - text-based interface

Programming Software Visual programming using EDWARE Visual programming depends on graphical blocks that can be dragged and dropped

Identify what the below program does Activity5– Page 23 Identify what the below program does

Answer : The above program is a line tracking program. It starts by tracking a reflecting line. Loop Starts If line is found Move Right Forward with speed 2. If line not found Move Left Forward with speed 2. Loop Ends Program Ends
