Hi, I want to find the instantaneous center of rotation of a differential drive robot. Assuming I know that the robot will travel with a particular linear and angular velocity (v,w) I can use the equations (given here http://rossum.sourceforge.net/papers/CalculationsForRobotics/CirclePath.htm...

thanks... reading the bum on a drunken street analogy calmed me down a bit.. enuff to be able to go and hit the books again... i hope i get something this time... :D if i don't its back to this thread ... :D :D thankyou everyone.. and i'll try getting a pair of bjts and experiment with...

i don't know I'm just scared of them.. i read the book and it goes over my head .. OVER my head.. using sedra smith and a systems approach to electronics... its just confusing... and i spend half the time trying to figure out what's happening to the electrons ...

okay for some strange reason I'm very very scared of bjts .. i don't know maybe i just don't get em at alll... is there some site or some book that explains bjts in the simplest terms?? u know something crude that gives u the basics??

okay i was reading the book "div, grad cur and all that" i've just started for my exam. but i got stuck in the beginning. I'm attaching the page because i really don't get it . basically pages 14 and 15. i don't get how they calculate the components of u and v. if someone explains u i'll...

thats exactly what my teacher said. thanks! so so so much. he also said that u pick the diode that has the highest potential difference. :D

k but suppose i said that d1 was not conducting. and d2 was. then my circuit wud be different. how wud i check which assumption is right?

both.

zero?

here's another link hope this works. http://docs.google.com/Doc?id=dgcr4jx9_29fvfmp8dg"

Ideal diode questions final soon urgent help its actually an example in my book (sedra and smith, 5th ed) which i fail to understand completely! Question: the question is : Assuming the diodes to be ideal find V and I in the circuits. I obviously went through the example but it totally...

ok my earphones weren't working properly.. sony ericsson.. i had two sets of the headset and earphone pair.. anyhoo one of the earphones wudn't work if they were properly fixed in the jack but if i fixed the pin thingi lightly in the jack both wud work.. so i decided to open my...

cr and lr circuits help.. exam in a bit and I'm stuck! okay so here's my question : how is the peak voltage across the resistance (in a cr circuit) or the induction (in an rl circuit) = \pmV_{m}/(1-e^{-T/2\tau}) V_{m} is the max voltage of the pulse train. the m denotes max both...

we haven't done strings and stuff yet... its just very basic stuff at the momment... but i did the date thingi... i set space to 0 if space%7==0, and then in the end i set date to space and then set space to 0 again... so that worked out well... i don't get how to do the month thing...

okay so they asked us to make an entire calendar where the user inputs the first day of the month and month itself and a calendar is generated for an entire year.. so far I've gotten to being able to generate a good thingi for a month.. and well I've used a while loop to repeat till the months...
