As an interesting thought experiment, what should be done if it were found that BOTH sides were using chemical weapons?
Drop a few nuke's and level the country. Just joking!  I don't give a crap who used the chemical weapons just leave syrai alone... its not America's job to controll other countries.

Send us the spec/data sheet for the receivers you will be using.

Why not go green? Solar panel with a small battery bank?

For your Arduino I would go with this one…

For a collar your going to need to build your own Arduino or use a really small version. The program will be super simple, however, until you have all the parts it's obviously hard to start working on programs. Below is a link for an ir receiver that might work as well as a small Arduino.  




Best of luck!

I don't think any stores would be interred in such a product as they would probably lose a lot of money if people have a live up dated price. It would be better if it gave them the total at the end.

Also how about vision tracking? Could you use a camera to see what gets put in the cart? Maybe a weight and camera combo?

That is amazing! I have that same robot arm and I'm trying to figure out how to control it better. Right now I just set the servos to go to a certain point. What do you do?

If it can be done with legos you can do it with an Arduino.

Watch the video and look at ALL OF THE SENSORS they use!

Why not set a build cost classes. 

You could have an under $50 and under $100.
144  Using Arduino / Project Guidance / Re: Need Some Advice On Simple Robotics Project on: September 04, 2013, 09:06:16 am
I would not use a motor shield. I would buy 2 dual motor drivers. Also wait until you pick out your motors so that you buy one that can handle the current. How are you building the robot. From scratch? From a kit? And using dead reckoning is hardly ever a good Idea on a Robot. Use sensors!

Also I'm curious what competition this is.

Best of luck!

That is going to be tricky. With the servo control below you could potentially control 512 servos off of a mega. You might need more then one Arduino.

Would this work?

Looks like we posted at about the same time. Anyway your link is broken.

No kit but a simple google search helps

This might get you started…

Also, It looks like it would work with Arduino.
149  Topics / Robotics / Re: Advice on a robotic intravenous cart that automatically follows a patient on: September 03, 2013, 02:56:11 pm
Why not a vision sensor that track were a person is moving and follows them? The raspberry pi might work better for this project… 
150  Using Arduino / Motors, Mechanics, and Power / Re: Servo Burning Hot and not working. on: September 03, 2013, 10:34:43 am
The servo I dropped in was not pushed in all the way. After I pushed it in it works fine now. I still don't know why the first servo stopped working and got hot and yes I tested to make sure the wires were right.

Quote
If a servo is prevented from reaching its target position mechanically it keeps full power
flowing through its motor

That can't be the issue as the new servo works just fine unless the servo loses  torque over time. The servos are the same kind. The servo must have been the issue as the programing and wiring is correct. Thankfully its just a cheap servo not one of the expanse ones. I will just assume that it had issues.

Thanks for all the input.
