Did you google "DOF" or  "Degrees of freedom" ?????

Thanks!
Google said it was a 'depth of field' (???).
I had no idea, thanks a lot!

DOF = "Degrees Of Freedom"
Google will find many definitions on the full spelling.

Google "google autonomous car" then read.
This car has now been allowed to run in a few states but the google autonomous car legal liabilities have not yet been fully determined. There are many articles about this.

Mechanics and Construction / DOFS

Hi again, I have a question. I googled it, and all that, but couldn't find an answer.
What is a DOF? They were mentioned to me but I have no idea what it is.

Electronics / Re: VIBRATION SENSOR?
« Last post by jwatte on May 21, 2013, 11:26:13 AM »
Before you say "it won't work," you need to specify the parameters you need.
What sensitivity (in gs) do you need? Is 1/100th of a g sufficient? 1/1000th of a g?
What frequency of vibrations do you need to detect? 1 Hz? 10 Hz? 10 kHz?
Once you know this, you can look at the data sheets for the various sensors and accelerometers available.

Sorry, I'm not a Matlab user, so I can't help with that part.

Thanks!
I'm not planning to make one with a moveable turret, that might be a bit much, but I have most of it worked in my head, I just need to figure out the leg motion stuff.
I love the section 'how to fund for your robot' (http://www.societyofrobots.com/robotfunding.shtml)
That has helped me a lot!

I appreciate these responses and will investigate. However with the I2C, I believe this would not work because i will use it to detect and analyze low level surface vibrations

Case closed, somehow or another i'll figure this out on my own, I may make a thread with question about the programmin
