SAE (Society of Automotive Engineers) Chapter Trip – 2


so it says my advisor said these are higher would create their for research purposes so we can program them send comments to our computers and just like bring this together every controller robot if you want to use it works like joystick you’re just by the roadside No so he is just something that we did for fun but what we do for research is my advisor spoke about the a little so we are trying to get help from robots for m1 to monitor for my move to monitor can use these small devices these are simply you can think that very small computers they have processor they have a memory they also have some onboard sensors and also they have communication capability they have a wireless antenna they work very similar to the thing is they consume less energy so they’re completely powerless and as you see they can they work with 2mm a day we took the liberty is this device is convert more than a year you can use them so this is what we want to do we we get how profitable to extend the life of these robots are we extended it is to be gold nearby the sensor to collect the data we want to do this autonomously with the robot so now what I what I’m going to show is I will put this sensor somewhere we’ll hopefully see that the robot will find a good location to download the data and for would good location what I mean is you mentioned that this is a wireless router in your house and you are in your pan and some like you move your laptop bailable the signal strength with filter right so your internet connection store start to drop down so this radio signals are really unexpected it’s not like just distance but also orientation may affect and also even if you for example get closer the signals clang my job because of simulant you can imagine signals strengths as a ways so like two waves can cancel each other or they can they can get stronger so so because of its nature we cannot know like how we should go to find the location when we find a really simple algorithm basically we put a virtual grid on this workspace and our robot goes to each like grid squares and get samples from that try to find the location where you can start the download paper from one so basic idea is if the signal string is good then we can download it in a very short time so these things will not consume too much energy so we can next on the other so the same kind of effect happens with cell phone when you see signally basically bounces around right and the signal sometimes cancels itself gets wise in our houses were nothing comes up and you won’t take a few steps to the side on everything is great so the same thing is happening at a smaller scale here device whenever it sounds the radio signal it bounces off from the walls from the people and so on and the pattern is actually really weird so there are some dead spots very close to the device there are some very spotty away from the device so the point is the robot should be able to discover good spots by itself and download the data also adapted with a moment so if it’s a different unit complete and Shirley’s st. just the lift up side the vases this run with yeah the function is different so light finds a good location after it starts to find a good orientation as I told the door and national surveys of the offensive basis orientation it will go wreckage somebody watching has changed it shows it shows so for this demo we just so it doesn’t need to get default again so this location wasn’t good enough to that’s good enough for it but the other ones one so it depends on the threshold the interracial that you said for example it make sense what I put the threshold around and if I would say 107 let’s say monkey sorry that’s announcing yeah so the signal strength that i’m reading from the devices between 150 so 105 degrees good see and as I told it I mean it doesn’t mean that if it gets closer the signals pencil increase you can also depends on the m1 if you like think about like water weighs about the shape of our group the signals and bonds from the world and they can’t cancel each other so it is really not easy to say that this is a good even if it is get it even if it is closer it comes up the shape of the walls closely and then put signals can cancel each other how often is said sending the signal take so tenuous Herr Oberst for VT weekend
