Finally, today we had decided on our project concept.. We will making the “Desk Cleaner” robot..

We had faced many difficulties in building the suitable robot design.. However, it can be fix on the next time..

While I’m searching on the youtube just now, shockingly I had found many “Cleaner NXT” robot that had been made by others.. I had analyze their design, and for me, many things that we can adapt to our robot later..

At the class, I had use the ultrasonic sensors as the distance detector for the gap between the desk and the floor.. However, several of project in youtube uses the light sensor.. When I observe the video, I had founded that the light sensors are better than using the ultrasonic.. Therefore, I will innovate the previous design, but still to use the ultrasonic sensors to detect other obstacle such as wall.. So now, we will use three sensors instead of two just now.. The sound sensor is just an alternative to make the robot more “intelligence”.

Here, I had added the video from youtube.. Just see the video, and give your opinion.. Which is better.. However, our project is not the same as in the video.. But, we can use their ideas.. Right?

Floor Cleaning NXT

Comment above: Look at its ultrasonic sensors, it move to detect the wall..

Comment above: The robot is too fast, and too long.. The sweeper also too small..

Comment above: Hey, look at the LED at the above.. It make the robot more “attractive”..

Comment above: The best cleaner robot that I found. It so intelligence..

Comment above: Look at the below of the robot.. The sweeper rotating..

Table Cleaning NXT

Comment above: Simple.. But I cannot see the cleaning kit..
———————————————————————–

Comment above: I don’t know it use the light or touch sensors.. But two sensors are effective!
However, the sweeper seems not cleaning the table effectively..
