NXT Ultrasonic Sensor & Light Sensor

This week class session, we are exploring about Ultrasonic and Light Sensor that we decided to be use in our final project.

1. Light Sensor

This sensor is used purposely as robot vision. The sensor that also have same functions as light sensor is ultrasonic sensor. The light sensor enables our robot to distinguish between light and dark. it can measures the light intensity of coloured surfaces and also light intensity in the room.


2. Ultrasonic Sensor

This sensor enables robot to see and detects objects. it also can be used to make our robot to avoid obstacles, measure distance and detect movement.

Robot Name: Hit the Ball




We were required to build the robot and program it to detect the colour red and hit the red object. We programmed the robot and it was set up in front of a pedestal, where two balls, a red and a blue ball.

If the robot walked up to the blue and ignored the ball, but saw the red ball and knocked it off of its pedestal, then the challenge completed successfully.

Design and technology learning offer opportunities for students to develop their designing and making skills, nurture creativity and innovation through designing and making, prepare students for making contribution to life and work in a technological society and explore values about and attitudes to the made world and how we live, work and interact within it.

The introduction of robotics education as a part of design and technology subject for this semester is really beneficial as the research literatures on robotics education in several developing countries such as Australia, Singapore and Japan show that Robotics is a popular and effective way for teachers as a teaching tool for introducing students to important areas of Science, Technology, Engineering and Mathematics curriculum ( Johnson, 2003 & Perteet, 2005)

Jeneva Westendorf (2005) also says, robotics is a tool for learning through experience and discovery. Introduction to robotics at a young age could open doors and piques the imaginations of all students, encouraging diversity in the fields of science and technology. Besides, robot also offer the opportunity for creative expression, problem solving and contructionist learning (Wagner, 1998).

Hope that we gain 'something' through robotics learning for this semester and able to use the knowledge and skills we have in our future teaching wolrd.. ^_^

This blog is created purposely to record our journey in robotics learning during this semester. Here, you will see the progress of 3box-Ro-Bo-Tic in generating ideas and realizing the robotics project as required. So, don't miss to check it out!

First of all, let's me introduce you all to 3box-Ro-Bo-Tic team members..
