Well i know a bit in robotics and i know that you all will say i need to build a small simple robot to learn
Thanks to all who helps and please no negative comments thanks!!
I have re posted this topic here in the Electronics because i be leave it would fit here mostly because i am working on the inside of the bot now.
i know that you all will say i need to build a small simple robot to learn, Well i cant do that because i get bored with that stuff and at my school i learned how to build some but they always get the parts for us then we build, see where im going. I dont really know what i really need all i know is this.
Thanks to all who helps and please no negative comments thanks!! Grin
I'd use a PING since its more documented then the SRF05 - also the ping is cheaper http://www.societyofrobots.com/member_tutorials/node/194
OK, thanks man! Sweet now i have sensors!
Dont take this the wrong way - but it sounds as though you may be out of your depth with this Syth project. Start with something simple, do it well and knock grampas socks off !!
15lbs is a significant amount of weight, it means your robot have to be fairly big and powerful. For comparison, a standard hobby servo (hs-322) has 3.7g*cm of torque, that equates to only 1/2lbf for a 6 inch arm. And remember, the more powerful the servo, the more expensive it is.
You cant go wrong with HS645 MG servos for the armand an Axon, $50 MCU, Arduino, or Picaxe 28x1 for the board
50 grams is MUCH more managable.For a maze you need more than 1 sonar (especially if you want to move fast), ideally something like 16 sonars would be best , but I guess 3-4 would do. And if the maze is small, you probably want IR rangefinders instead.You might want this: http://www.sparkfun.com/commerce/product_info.php?products_id=319 It is a dual motor gearbox, which sounds like what you need.You could also modify a standard servo to run continously. That has the advantage of working with the RC receiver.
L298 should work for you. Just one can drive two motors.
As I said, if you're going to buy the AVR programmer you should go with AVRs. Most people use the ATMega8/16/168 series.The axon is more like a complete control board, you'll save some money making your own board, but you need some experience to do that. The Arduino's are cheaper, about 30 bucks.
Yeah, that's the Arduino, all built version. You will also need a shield, to be able to make the 3 pin headers for sensors and servos, but it comes out as a kit: http://www.sparkfun.com/commerce/product_info.php?products_id=7914 so you need to solder and to actually make the connections for the 3 pin headers that are not documented. We may be able to give you hints in that direction.But you will be better off buying Airman00"s Roboduino, that will have the 3 pin headers allready installed.
