Mini-Giant Robot Tracker|
Posted on Saturday, October 01 @ 07:33:51 EDT
Our new work, tracker, was created on a PCB chassis as this is usually the way we do it. With sound sensors shaped as ears on the front part, glued-on moving toy eyes on these ears, and the smiling mouth in the front gave it a jolly look. |
Our robot has six main function modes, and of course bright glowing neon bulbs (I just love this neon stuff).
Command by sound
Command by light
If you want to see our Tracker while working, go download the videoclip below.

You can find pictures of Tracker taken from different angles and additional details of the construction steps in the following text.
In Life mode, our robot is usually motionless, and busy with observing the incoming light and sound, and responding to these with light and sound effects. It also blinks its neon bulbs with different effects.
You can change the function mode of the robot by touching the button on it. The robot also switches function modes every time it is turned off/on. You can also use this turning off/on method to switch modes.
In Sound Tracking mode, our robot moves depending on the sounds received from its environment. Having two ears, the robot can discriminate the direction of the sounds. The robot turns right, if the sound comes from its right, and turns left if the sound comes from its left. When the sound comes from straight ahead, the robot advances towards this sound source. It can find the sound source easily using this method. You can walk your robot from one room to another by clapping your hands.
In Light Tracking mode, our robot seeks the brightest spot by constantly scanning the area from left to right and vice versa. The robot moves towards the spot beeping twice if the bright spot is on the right, beeping three times if the bright spot is on the left, and beeping long once if the bright spot is right ahead.
In the Line Tracing mode, our robot follows a dark colored line on a light colored surface. To be able follow the line precisely, the robot keeps the motor speeds under control by driving them with PWM.
In Command by Sound mode, our robot follows the commands given by clapping hands. One clap - forward, two claps - backwards, three claps - left, four claps - right, five claps - turn on neon bulbs.
Command by Light mode is similar to the Command by Sound mode. The only difference is that the commands are carried out by light instead of sound. You can command your robot in a dark room by using a flash light or just directly turning the room lamp on/off.
Our friends who actually want to build this project can examine our Lightbug, Soundbug, and Linebug projects in the archives section. You can join them together as in this project, or you can just build them separately. Here are the links to the articles of;
