Hardware / Phototransitors power supply
« on: October 14, 2014, 02:14:31 AM »
I have a doubt about the phototransitors power supply. In my mouse i have a very small regulator max 30 mA powering the analog part of the mouse (Gyro and phototransitors) but my doubt is if 30 mA is enough or the phototransitors consume more power.

Hardware / Help with my first mouse
« on: September 19, 2013, 12:47:27 AM »
Finally i have some time to spend on my first micromouse but i have some doubts and questions.
I will be using the fauhaber 1717 with 16 line per rev encoder and using the 4 wheel configuration.
What is a better distance from the floor: 1,5 mm or 2mm?
Does someone knows where to buy 17 mm mini-z wheel?So the ending wheel will be 22mm.
In your opinion a resolution of 0.3 mm on the floor is enough to control a robot? i will also mount a gyro.
Should i mount an accelerometer to help the resolution or it is just impossible to use in such application?
With this low resolution you reccomend using 4 or 6 sensors?
This question is for the admin, i read that for your new mouse you have a gear ratio of 11:40, that is 3.63636363... how do you deal with this numbers? You use float or fixed point integer?
Thank you for the help and sorry for all this question :D
