Umm Coding

So long time no blog, but grad school visits + spring break + thesis === NO SLEEP! Ok yea and no work on ANYTHING except my thesis :(.

Luckily, I am not behind on what is due for this week. So on Tuesday I finished up challenge 5 & 6. 6 should have been insanely easy but it wasn't because I had pulled an all nighter earlier and my brain wasn't working! I CANNOT code on no sleep :(. Here are some pictures of my code :).

Challenge 5 code is below:
So the nice thing with using light sensors instead of trigger sensors, is that you don't need to code in a wait time at all. So all done with challenge 5 :).
Here is the bread board connected with 2 different switches. I used this for testing challenge 6. I was able to make the multiple threads using this code below:
 
So I just modified Robbie's code to include a second edge and if either edge is triggered then my bread board flashed -- SIMPLE. Ok I lied -- I had no problems with challenge 6 it was challenge 7.2 (described below) that took about 30  minutes longer than it should!

 
block test-t1 is how I got challenge 7.2 to work. Basically I did a nested if statement that allows you to check if it should add to count or subtract from count. test-ed2 is what I wrote for challenge 7.1 (the easy part!). Basically the net count was very simple. I am on challenge 7.3 now. I have created and built my lego car (woooot lots of fun) and just need to code challenge 7.3 which should be no problem. I'll post pics of my car and the code from challenge 7.3 on tuesday!

Hopper Last

Image
So we made Hopper hop....well sorta! We built a bottom for hopper's body by adding 6 puzzle pieces! Lots of fun making puzzle pieces that fit together in a tight fit. Then we have a small tail piece of foam that helps with the balance and the hop of hopper. We got in the long axel and put it in for the double axle of the engine. Unfortunately we picked up the extra long one which messed up our balance and looked REALLY strange. So instead we decided to use the shorter 100 mm axle (not the 150). But at this point our engine started acting up! So after an hour and a half of fiddling with the engine, we got it to stop making weird noises when it ran. We also decided to do some soddering. We soddered the batteries with the engine and added an on/off switch. Lot's of fun soddering again. After all of this our hopper is mostly working. I've shown you tons of pictures so here are the two new ones from friday: This is hopper with the 150 mm axle -- doesn't it look weird! yo...

Thermal Work - Matlab -- Write up

So I worked with Jeff on the matlab thermal work, since I had missed a fair amount during thesis time. WE managed to finish up everything. Umm ok here goes: So I worked up the part 1 of the thermal challenge in class with Robbie. The cooling and heating of coffee was really easy. But hey, I've done tons and TONS of matlab coding this semester (aka > 200 pages of matlab codes). Any who, what happens with bang bang is lots of oscillation for the control, aka the temperature of the coffee oscillates around the desired temperature. When you code in proportional control, you have trouble reaching the desired temperature. Instead the coffee tends to be right below the desired temperature and never quite reaches the desired temp. I guess Starbucks can't use proportional control then! It is quite fun to add in a time delay for the proportional control and bang-bang control. With bang-bang you see a fair amount of overshoot. You see some overshoot with proportional control too. a...

Hopper Finale

Image
He works! It's crazy soooo crazy :). Here are some pictures from hopper finale. We did all of the sodering and used the smaller 100 cm axle. We also got the alignment correct between the two legs. And he hops!!!! There is a movie I have, so please email me if you want to see it :). I don't know how to post it here so yea. We decided not to redo any parts as he works pretty solidly! There was one idea to make the big rabbit legs a tad bit smaller so that they rotate completely freely without touching the floor surface when he is hopping, but the weighting of the legs with screws really means that this isn't an issue! I think hopper is adorable and my partner is brilliant. I am good with solidworks and printing but she is good with lots of everything else!
