Please recommend some electronics
« on: April 13, 2008, 11:23:23 AM »
Hi.

I wish to build a simple robot and need some electronics and a development environment.

The robot:

The robot should wait for a start signal which would consist of pressing a button or, even better, receiving a signal from a hobby type radio control.  Once started, a rotator would rotate to a start position, flash switch a low voltage circuit on for a duration of ~200ms, rotate a predefined number of degrees, flash switch the low voltage circuit, rotate....  and so on.


Wait for start -> rotate -> switch -> rotate -> switch .....

It should do this for 360* of rotation.

It should be completely battery powered so I can move it around freely.


The rotator:

I would like to use Lynxmotion's rotator as it looks to be exactly what I need.

The development environment:

I would much prefer to use Linux to develop and test the software for this microcontroller based robot.  I have plenty of access to Windows but I spend 99% of my time with Linux so this is where I am comfortable.

I would like the language to be C.  I have a few decades of C experience and prefer this language but I can write in pretty much anything.


The electronics:

I would like to build the least amount of electronics possible.  I can certainly add some supporting circuitry but I don't want to go to the board making level.  If I can spend a little more on someone else's controller, this is what I much prefer.


Current ideas:

I've done quite a bit of reading on this site and others.  It would seem I need to look at an AVR controller so I can cross-compile the code on a linux box.

I would appreciate it if someone were to suggest a board that can control 3 R/C servo channels of output and also has a few channels of input.  I'll need a programmer and all that stuff too.  I prefer to keep it under $500 but do have some flexibility.


Thank you in advance,

Tom (the new guy)

i got just the development board you are looking for , check in this site

http://www.digilentinc.com/Products/Detail.cfm?Prod=CEREBOT-II&Nav1=Products&Nav2=Embedded

and for the programmer look in this link
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=ATAVRISP2-ND

and the budget your keeping is way more than what you need , you can actually make your robot within a budget of $150

This sounds like an ultra simple project . . . with the exception of using linux . . .

Look up the Arduino, probably the cheapest/easiest way to go for what you are requiring.
