Getting ready for Japan

With the the Japan 2010 contest only about three weeks away, there is a burst in activity from Japanese mouse builders as they prepare for the contest. Most recently, Kato-san shows us how close to the edge a top-performing mouse will have to run.

New camera time

Updated my camera today. The Casio Exilim EX-FH100 is a newer version of the EX-FC100. It does everything the older one did and then adds a few more features. Oh, and it is black. Somehow, that makes it better just for that reason.

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… (more…)

Bit Banding in the STM32

Wondrous though the STM32 (ARM Cortex M3) might be, it makes something of a meal of atomic access to individual bits in memory. The technique used is called bit-banding. Although it is simple enough in concept and pretty friendly to the assembly language programmer, it is easy enough to get lost in C. Or should that be at C?

Calibrating Reflective Sensors

By far the most commonly used micromouse sensors are simple reflective types that give an indication of distance by measuring how much light is reflected from the maze wall. While the response is repeatable and related to distance, it is quite difficult to get an accurate answer. This is how the sensor readings can be converted into an actual distance… (more…)
