Selecting the best micromouse sensor design is a study in electronics, physics, geometry, maths and coding. Here I will look at some of the design considerations for the sensors in the next iteration of my micromouse.
UPDATE: Unfortunately, we will not be able to arrange a group purchase after all. Sorry for any inconvenience. It may be possible to arrange a group purchase of Faulhaber motors. The exact model would be 1717T003SR with IE2-512 encoder. If enough … Continue reading
My micromouse generates a lot of data. I log speeds, sensor readings, motor controller parameters. All sorts of things. Often that data just makes me worry. Most recently, I was noticing that there were some large variances at speed.
Travelling to contests is great. Except for the bits and pieces that you need to lug around. For several years I have used a smart charger for my LiPo batteries. It is a fine charger but bulky. Along with its … Continue reading
I enjoy working with the STM32 processors. They are easy to use, powerful and cheap and there are lots of options for developing code. One minor annoyance is the question of a programmer.
While it was very good of ST to make the fantastically inexpensive and versatile STM32F4Discovery board, they have made things a little difficult in the choice of peripherals in places.
Most commonly, the speed and direction of the motors in a micromouse or other small robot will be read from quadrature encoders connected to the drive train. One of the great things about the STM32F4 processor is that it can … Continue reading
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
Micromouse sensors need shielding to work at their best. Here we are going to show you how to make a simple, flexible light shield for your micromouse sensors that will cut down the effect of ambient light and reduce leakage … Continue reading
Designing electronic circuits takes knowledge and experience. Sooner or later, you have to put your idea to the test. Generally, this means building a prototype. Even with the best circuit simulator software, you ended up with unfriendly or expensive products. … Continue reading
