Micromouse sensors aligned the easy way

An essential part of setting up a new mouse is the proper alignment of the sensors.  You micromouse sensors must have the emitters pointing exactly where you want them to and the detectors have to be aligned to get the … Continue reading

Comparing the ADXRS610 and ADXRS642 gyros

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.

Choosing an emitter for micromouse sensors

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 … Continue reading

Sensor Alternatives to the TSL262

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. … Continue reading

Measure angular error using front sensors

The front, or forward-facing, sensors on a micromouse have several uses. Apart from detecting the distance to walls ahead and obstacles on one side or another, properly setup forward sensors can be used to measure an angular error with respect … Continue reading

Front Sensor Replacement

My micromouse, Decimus 2A, has not been behaving well. The most notable problem is that detection of the wall ahead, and the distance to that wall has been erratic. Worse, the problem seems to come and go. For a while … Continue reading
