Here is my latest robot; "The goggles". The most advanced robot to be published on our site so far with 3 microcontrollers onboard which communicate with each other by parallel busses..
It walks on its two feet like our previous walker robot "bigfoot". In fact this robot is an improved model of the bigfoot. This has got an IR (infra-red) obstacle detection system which enables the walker to detect obstacles up to 40cm range. With a single modulated IR detector and 4 IR LEDs, the robot can detect obstacles in front as well as both sides.
Additionally, the goggles has got a pair of ears. Two condenser type microphones which signals are amplified by two separate circuits. The signals are then sensed by the onboard microcontroller. The main controller can detect the length of sound signals as well as the phase difference between signals coming from the left or the right. So direction of the sound coming, can be detected easily.
A visible light sensor is present. The environmental light can be measured analoguously within 32 steps ( 5 bits).
There is a piezo buzzer to generate sound. The signals for the sound generation comes directly from the main controller, from some asm routines written to make sound efects, notes & some music. Sounds can also be used for the robot to express "its feelings".
If sounds are not adequate, it also can express its feelings via the 5x7 dot-matrix display onboard. A simple face drawing showing some feelings will tell the mood of the robot, to the outside world. A separate controller will drive the LED matrix display according to commands sent from the main controller.
Still working on it. no circuit schematic or hex codes are ready yet. I'll need some time for completing the project and publish the sources.
But there are some more photos of the project available.. Read on!
