Analog Devices recently release new vibration rejection gyros which seemed a perfect fit for use on a micromouse. Since I was using the ADXRS610 on Zeetah V, I temporarily mounted an ADXRS642 to ZV to compare the two.

Finally, a way to solder the Analog Devices ADXRS610 gyro… The last time we attached a gyro, we overheated the board and the board delaminated. This time, we use a skillet and avoided that problem.

Most commonly, micromouse reflective sensors use Infra Red LEDs as the emitter component. That is all very well and suits many, or most, phototransistors. the thing is, you cannot easily see where they are pointing and what kind of illumination they are providing. Here is a sample of 13 different emitters…

The TSL262 sensor has been popular with a number of micromouse builders. It is compact, easy to use and results in a low component count. A common alternative is the use of a simple phototransistor in an emitter foloower configuration. So, why change what works… (more…)

Now that I had the layout, the next step was to cut and drill the plywood.

While there are many techniques for doing this, I ended up getting help from a friend who has access to water jet cutters to do this.

The annual winter micromouse contest was held at Millenium Point in Birmingham by the University of Central England on Saturday November 19th 2011. Unfortunately, I was not able to attend this year but I gather everyone had a great day. I have managed to gather some results and the finals maze though…
