Topic: Lifting
Instruction: Lift up a ball and put it in a recycle bin.
Objective:
By the end of the lesson, students should be able to:
a) Getting used to the Lego Mindstorms
b) Build a robot that can deliver things
c) Build a robot that can lift up things
d) Build a robot that can lift up things using the light sensor
e) Build a robot that can put things in a particular box
Materials and Tools:
a) LEGO Mindstorms Set
b) Light sensor
c) Ball
d) A box
Procedures:
a) We’ve given a theme where we have to build a robot which can lift a ball, and put it in a recycle bin.
b) Design the robot using our own imagination
c) Fix the components of the robot according to what have been planned
d) Set up the program using the MIDSTORMS software
e) Download the program to the NXT brick
f) Test the robot either it functions well or not
g) Modify the program and the robot so that it will meet the objectives.
h) Present it to lecturer and friends.
Results:
The robot managed to lift up the ball when sensed by the light sensor and it moved back and put the ball in the box when it hit the box.
Problems Encountered:
During the practical work, we found that it’s not easy to use the light sensor as we have to set the percentage of the lights. This is because what we see is not the same as what our robot can see. We have to set it several times but managed to overcome the problem finally. Other than that, it is also not easy to make the robot lift up the ball as we have to set the hand of the robot using degrees. However, we managed to overcome the problems after a few attempts.
Conclusion:
If the robot managed to follow the instructions given, it shows that the objectives of the lesson are met.
