Brainibot is a small mobile robot with a light sensor, two touch sensors, two motors, a sounder and an 8-bit computer running at 4MHz. It heads towards light while avoiding obstacles in its path. It is supplied as a kit.
Behaviour
The robot
moves forward while turning to the left and right. When it has
turned left, it measures the light level. When it has turned
right, it measures the light level again. If there is a difference
between the light levels, it chirps and turns away from the darker
direction. The overall light level should be increasing. So if the
robot has not seen an increase for several seconds, it reverses
then spins on its axis. As it spins, it measures the light level
and chooses the brightest.
Class Packs
"Class packs" are kits of unsorted components. Those who have had experience with classes building the kits say that the "class pack" is far better than the pre-sorted kits. The biggest mistake that the children make is to put the transistors in the wrong way round or in the wrong place. So you give them, say, just the PNP transistors; they solder them in and bring the pcb back to show you; if they're in the right places, then you give them the NPN transistors, etc.
The prices
are lower for large orders of course.
