I used to have a robotics hobby, then I got into FIRST seven years ago and it destroyed my robotic hobby, no personal time for that.  As it was said already it becomes crack for some, it is addictive.

 

FIRST is more than robots, kids learn teamwork, how to run a business, fund raising, web design, working through team issues, real world problem solving, PR and much more.

 

There is a real family atmosphere as you go to competitions and there is more yelling and screaming than any high school game I have gone to.

 

My suggestion if you are just getting started is start with FTC, much more manageable and many issues are the same just smaller.

 

If you do an FRC get another team to adopt you, they will want to do that, FIRST encourages them to do so.  Next for us, the secret is the college mentors that have been in FIRST since they were in highs school.  They bring in a lot of experience being involved in FIRST in the past, I am the engineering lead for our team but I turn to our college mentors often on the best way to go.

 

So go for it, you will have a run for your life.

Hi guys,

Remember my thread on here about using a "ovenizing" resistor to stabilize a 555 timer (while working on my ultrasonic range finder)?

Well, now I've decided to do something simpler (to both me and the general audience); so I've decided to do 555 accuracy vs. junction (chip die) temperature. 

To the original person who gave me the ovenizing resistor suggestion (and others): Where/how did you know that changing the operating temp of the chip will affect the performance? 

Thanks

Ray Xu

so most likely it would do the same for execept for in frequency

While the 555 is actually a pretty nice design, as far as the trick they use to
prevent voltage variations from adversly affecting the freqency, it is still an
RC oscillator. If you need real precision, you should use a crystal oscillator.
If you need REAL stability, then you get into a crystal oven.  If you need to
vary the frequency in steps, you can use the PLL routine and change the
frequency in discrete steps.  If you need a small amount of semi-linear
variation in the frequency, like a VCO, you can "pull" a crystal frency over a
small range by using a varicap diode and appropriate padding caps.  As I recall,
series mode crystals work better for pulling than paralel mode, but check me on
this, my memory isn't what it used to be. :)  Trying to get real precision and
stability out of an RC oscillator takes more effort than it is really worth. 
There are better methods that are MUCH easier to implement. It all depends on
the EXACT application you are going for. As far as die temperature affecting
stability, in the 555 design the biggest variation from that is likely going to
be in the internal voltage divider used to establisht the 1/3 and 2/3 trip
points for the comparator.  As long as the internal resistors track each other
fairly well, which they should being close proximity on the die, a small
variation in die temperature shouldn;t affect accuracy that much.  You greatest
source of error is going to be the external R's and C's used--mostly the
capacitor.  Definately use a high quality cap, like a quality NPO ceramic, that
is designed to have a zero temperature coefficient, has a low leakage dielectric
material, etc.  Metal film low tempco resistors are available, but expensive,
and you may not find the exact value you want.  A wire wound multi-turn trimmer
may be a better choice---wire wound pots, as much as I hate them for their
tendancy to develope flat spots, and skipping from one turn to the next right at
the spot you want to set them at, do have a much better tempco than cermet pots.
Good luck!

David, thanks for your reply.

Like what I did in my ultrasonic range finder, I used one of those rectangular cement resistors placed on top of the 555 with heat grease and a thermistor for temperature feedback in between; and wow it made a HUGE difference.

Without the resistor; the frequency varied more then 15 KHz randomly at start-up.  With the resistor and the heating, I had no variation of +/- 200 Hz (out of 40KHz).

So you're saying that the heating is mainly affecting (and "matching") the internal resistors?  Or is it all the transistors and other parts in the 555 thats making the difference?

and a rf receiver link below with datasheet pdf

http://www.jaycar.com.au/productView.asp?ID=ZW3102

I would like to know how to implement the transmitter to the pc via serial port
and how to implement the receiver via a bs2 so i can control a LED wirelessly
using a pc.

Im starting off with something simple like turning a LED on and OFF and then
working out how to turn a servo.

Any help will be greatly appreciated.

I've used cheap transmitter/receivers very like that (but not that exact
model) and found that they're AC coupled.

What that means is that if you send a stream of alternatate 1 and 0 it gets
through fine but if you send just continuous 1 or continuous 0 then the
output from the receiver soon goes to an intermediate value.

That's a common problem for a lot of different digital data storage and
transmission devices and various techniques have been developed to overcome
it such as "bit stuffing" and "Kansas City" or "Manchester" encoding. The
general idea is to make sure you never send a long stream of 0 or a long
stream of 1 even if the data includes such streams.

I'm not saying that your transmitter/receiver will have such problems but it
could well do and it's something you should be aware of.

The question is, exactly how soon does the receiver go to an intermediate
value?

Serial data from a PC has the format
     "1" start bit
     "d" data bit
     "d" data bit
     "d" data bit
     "d" data bit
     "d" data bit
     "d" data bit
     "d" data bit
     "d" data bit
     "0" stop bit
So even if the data includes a stream of 0 or a stream of 1, the bits sent
to the transmitter will include a few 1s and 0s. That might be enough for
your transmitter/receiver. Is your receiver capable of correctly receiving
eight 0 bits or eight 1 bits in a row? You'll just have to try it and see.

A simple test is to connect the transmitter to the serial port of a PC. If
you like, you can power the transmitter from the RTS line of the serial
port. A serial port produces 9V so you'll have to reduce that to whatever
voltage your transmitter needs - probably 5V. Use a 7805 chip. Then do the
same for your receiver in a different laptop PC. Get the transmitter PC to
produce a stream of serial data. There are lots of free serial port test
programs available that will do that (for instance my RS232.exe
http://www.peterbalch.btinternet.co.uk/prb00047.htm will just "count" to the
serial port).
Then walk around the house with the laptop and see how far away you can
still receive data reliably (RS232.exe will check that it's receiving a
valid "count"). That's a good test I always do with any new
transmitter/receiver pair.

As you can imagine, the problems get worse as the distance from the
transmitter increases. The solution is to make sure that your data always
includes plenty of 10 or 01 pairs.

For instance, to turn on your LED, you might want to send the data byte 0xAA
(which is 10101010) and to turn if off, send the data byte 0x55 (which is
01010101). That has a much better chance of getting through reliably than
sending 00000000 and 11111111.

If you're sending more complex commands to a robot, then choose a command
set that includes lots of bit changes. Here are 16 different commands each
fitting into a single byte:
     01010101  forward
     01010110  reverse
     01011001  stop
     01011010  forward right
     01100101  reverse right
     01100110  forward left
     01101001  reverse left
     01101010  spin left
     10010101  spin right
     10010110  front lights on
     10011001  front lights off
     10011010  rear lights on
     10100101  rear lights off
     10100110  beeper on
     10101001  beeper off
     10101010  shut down

Unfortunately, you've halved your data rate but for simple robots that's
often not a big problem. And it's very easy to tell if the data has been
corrupted - if the byte you receive is not in that set of 16 then just
ignore it.

Thanks for the advice peter. On the data sheet it said the max voltage of my
transmitter is 3volts. Is there another chip i can use to get the voltage down
further?

Allegedly, the 7803 exists but I've never seen one. Maybe use a LM317
adjustable regulator and a couple of resistors. There are fixed voltage regs
that will give 3V from a 5V supply (but I don't know one that will do it
from 9V).

I'd probably just use a zener diode and a resistor to make 3V from the 9V of
RTS. (I've got a drawer full of zeners but no drawer full of LM317s.)

For testing, you could just power it from 2 AA cells.

You'll also have to worry whether the 9V of the TX pin of the PC serial port
will damage the transmitter. Again, I'd use a zener and resistor to clip the
Tx signal down to 0V..5V.  But if I didn't have a zener and was being lazy,
I'd just use a 100k resistor to limit the current into the tranmitter's data
pin and hope for the best.

Peter,

 

In the notes to your Quad.exe program, you say there are 4 gaits (after removing mirrors and rotations).  But you show 6 gaits in the program.  You then go on to say that two gaits completely stable, which ones?  Which ones have to shift the COG backwards?  Which one does a cat use?  OK, I need to study them more and discover for myself.

Those guys making the suggestions on the MSDN forum are obviously the trained
experts, so they should know what they're doing.

What is this "my robot computer" that you are talking about? Is it at least a
WinXP with SP2 machine?

For my part, I'm no expert, but have been using VB and VC# [but not VC++] in the
2005 and 2008 versions on my WinXP. I have sent just the .EXE executables, with
no install files, to other people to see it they would run ok. And they run
fine.

It's my understanding you need a machine that has the .NET runtime compiler
already installed to get a bare .EXE to run. This will normally mean having a
WinXP SP2 or later machine, which I believe comes comes with .NET framework
installed as part of the OS. Just a guess, not an expert.

I have never been able to run an executable compiled with express on a
different machine.  In every case, the program had to be compiled on the
machine where I wanted to run it.  This problem does not occur if you
use a non-express compiler.

Interesting. I wonder why it works for me. Can I send you one of my Express

Difficult to follow your post. Are you sure .NET is installed on the ITX system?
Also, have you tried your executables on another desktop or notebook machine
with full operating system installed?

I have had that issue (with different compilers) in the past.   Find depends.exe
somewhere on the net and run it on your target machine.   It will tell you what
files you need to have installed... what files your program 'depends' on.
