Yeah, that’s what I thought. (obviously) I guess we’ll see what happens when I get my midterm back...

First off, I apologize if this belongs under homework help. It’s kind of a grey area I suppose... Anyway, I just finished my linear circuits midterm. One of the questions on the midterm had a circuit we needed to solve using node analysis. That’s not the question, though. I’ve crudely redrawn...

Homework Statement Given that the current flow is due to electron flow, state whether electrons are entering or leaving terminal 2. i _____ --> | | - -----|1 | v | | + -----|2 | |___| Situation A: V=40V, i=-10A Situation B: V=-60V, i=-10A Homework...

Yes, the motor limit is ruining many of my plans as well. Good luck to you as well, what team/regional(s)?

1: The surface is very uniform, otherwise I wouldn't have considered it either. 2: Encoder to determine wheel speed. Accelerometer to back calculate velocity (or possibly just use the acceleration). I have considered your suggestion as well, but don't have room for the undriven wheel. 3: Yes...

It is an electric drive train. The electric motors power drive wheels. robotics?... yeppers.

I think comparing it to the pwm signal should do the job. I'll post the results after the tests, which will hopefully get done this weekend. Thanks for your help.

I suspected that as well, but I plan on doing some tests the next time I have a chance to work on this. Do you think the drop would be noticeable enough to use as a guideline?

I am trying to figure out what would be the best way (by best way I mean the cheapest, and simplest effective way) to detect slippage of the wheel. The surface is very low friction, somewhere in the range of 0.05 mu. Here are my ideas: Sense current, watch for spikes/troughs monitor wheel...

As we speak!:-p Yeah, EE seems likely. I don't think I could do it without at least a minor/option in CS. Way too little programming in any of the engineering courses for me.

Yeah, I'm actually browsing over the course lists for CE, EE and MechE right now, to see which of them I like the most courses from.

I was reading the http://www.findoutmore.uwaterloo.ca/programs/full_description.php?program=Electrical%20Engineering" with a double major/minor in CS, would that be a pretty good grounds for robotics. Keep in mind that I don't want to just build robots, that is just something that seems to well...

This is why I was thinking of doubling CE with CS, As its not really the mechanical that I enjoy, but the electronics and AI, so that would cover both, and I would get the engineering degree.

That's a really cool resource. Thanks. This might even help me with my robot arm, nice.

How's this look: v=\frac{d}{t} f=rot/t 1rot=2 \pi r^2 f2 \pi r^2=v F= \frac{4 \pi^2 m r^2 f^2}{r} = 4 \pi^2 m r f^2 Edit: I changed the graphs and the lines were just as poor, so I don't know why I decided to square them in the first place, thanks for pointing that out.
