Simpler sensor emitters

Simpler is often a good thing. For the new mouse, I wanted to make the sensor arrangement as simple as possible. One way is to drive the emitters from the battery supply...

Calibrating Reflective Sensors

By far the most commonly used sensors on a micromouse are simple reflective types that give an indication of distance by measuring how much light is reflected from the maze wall.

Sensors and shiny maze walls.

Among the various thing you will hear said by contestants at a micromouse contest, the topic of walls will frequently come up. Generally in some disparaging way that indicates that the walls are in some sense to blame for their misfortune. I have certainly said so more than once but what effect do shiny walls have?

Tony Wilcox of Birmingham City University has been working with the design and implementation of Infra Red wall sensors for their student micromouse design. This type of sensor has become common in mouse designs although there are several variations on the theme. Tony’s version uses readily available parts in a robust and repeatable design with a couple of extra tweaks that make it possible to use the same sensor to measure distance over a very wide range of distances without having to change the drive current to the emitter…
