Anyway, still in the vein of attempting to give my bot some more brains than simply non-collision movement I am looking at gyros, accelerometers and magnometers. Hoping to figure out a fairly accurate method of DR.
Does it make sence buying something like this with the 3 different components on one board + a dedicated AVR 328 processor or would I be better off buying the components seperately? Arguments either way would be appreciated.
I think the prices are high but so is the time involved to make
I think in part it depends on how much time and experience you have. If you don’t have experience with accelerometers & gyroscopes, surface mount soldering, PCB layout and circuit design, expect to be at it for awhile, to learn a lot, and to save possibly nothing depending on your costs: boards/components/shipping/possible equipment and defects from learning.
I can only assume you are talking about dead-reckoning, but it always helps to spell it out.
I was more talking about buying seperate modules already on seperate breakout boards as opposed to buying the components and doing all the soldering myself.
I have done that for an arduino clone and also a motor controller, but for the 10-15 pounds I saved I took a good 10-15 hours to do it… design, solder, test etc. learning experiance but at a rate of £1 per hour it certainly was not worth it in a strictly financial sense.
I decided that saves £40 for right now. Maybe when I am ready for the gyroscope I will buy a gyroscope breakout or the 9 DOF if I really need it.
So my DR for now will consist of angle turned + time traveled at pre-measured speed… simple but my research into DR using INS indicates this is not a trivial subject.
