|This is a mobile robot, which is controlled by a neural network controller. The neural controller is implemented in form of a software in the microcontroller. I am using the robot for testing and experimenting with various techniques of autonomous navigation.
The Neural Network used is a simple feed-forward network, which not only controls the motion but also decides on the amount of sensory input required. The goal of robot is just limited to autonomous navigation in the direction where the obstacle is most distant. Thus, it forms a purely reactive system. (I had to put this modified reactive NN in PC and not in microcontroller, later).
Dimensions: Length: 46 cm; Width : 30.5 cm (excluding the wheels); Height: 30 cm;
The cost is US $100 ONLY because:
I have named the robot 'R. Daneel V4' after 'Daneel', a character in Isaac Asimov's novels. Asimov first coined the term robotics. 'R' stands for 'robot' following the nomenclature used by Asimov.
Problems: I'll tell you a funny one.
The ultrasonic sensor used doesn't detect cloth (coz its rough surface and the critical angel problem....). Thus a person standing in its way must be wearing Shorts !!.
