Thanks everyone!  I've narrowed the list to my top 10!

Excellent name!  You're allowed write-ins.  I will add it to the list, for when we vote internally.

The Prize is an iPad or Quadcopter if we choose YOUR name.  It will fly autonomously, follow you, and take a video while you do extreme sports or make a video blog walking thru a field.  It's friendly, safe, ducted, made out of foam, and looks like a flying saucer.  Here are the names so far.  Please pick 5 of them that you like best by typing them below.  It will be a 5 Million dollar advertising campaign this summer.

4  Using Arduino / Project Guidance / Re: Collision avoidance on: February 11, 2014, 05:58:25 am
No, only 90 degrees, 1 image.  I have found a laser dot before years ago for a different project, in an image.

Great solution!  Unfortunately we have already designed the hardware.

I don't see how Bluetooth can get me better than 30% of the actual distance in accuracy.  Angle too?  Links please?
6  Using Arduino / Project Guidance / Re: Quadcopter Follow me on: February 10, 2014, 08:48:28 pm
Ours is soft made out of foam.  The props are enclosed in ducted fans.  I will look into Bluetooth.  I will explain my 2 ideas later, after I hear some more creative thoughts?  The reflection from the laser is captured by a camera, that's how I'd know the angle.

The arduino can process a serial JPG image.  Or a Raspberry Pi can much faster.  Can you think of a better way instead of a laser to avoid a collision?

I've got 2 ideas to make a Quadcopter follow me while walking.  GPS is not one of them.  Either ultrasonic transponder that measures the angle between Quad and human by triangulating from 2 senders.  Or a laser line reflecting from stop sign material on the human subject.  Either one should give me the angle to the target.  Any better ideas?

I'm building a smarter Quadcopter.  How can I detect a tree, human or vertical post from 10ft away? 

Certainly Ultrasonic would work.  But then I don't get an exact angle.  Just left or right with 2 sensors.

I'm thinking of using a horizontal laser line.  When it hits a nearby objects it will be much brighter than far away.  With a camera I will know the exact angle.  I can calibrate the sensitivity to only detect less than 10ft away. 

Any new ideas?

Thanks for all the ideas!  Please anyone let me know if you have success building one of them.  For the moment I'm working on our Flying Robot...

I'm hoping you experienced Robot builders can help me with some brainstorming for a new project.  I need to turn a "robot" to face a human.  The human could be carrying an iPhone with GPS, ultrasonic sensor, laser reflector, anything small.  Within 15-30 degrees would be close enough.  I also need to calculate distance, that's the easy part.  So they will already be carrying an ultrasonic device to repeat back the ping.  GPS is not good enough because they may be less than 30 feet apart.  At larger distances this may be the best solution.  I have tried a laser on a stepper, this works so long as there is a Retroreflector mounted on the human.  The device below has a stronger signal when pointed within 15 degrees.  Is that the simplest solution?  The range is not enough with a passive reflector.  What range would I get with another ultrasonic device to ping back?

How about 2 IR sensors with a wall between them?  A stepper to turn it until both are equal?  What are the pros and cons for this method?  Range?

If there were an accurate (100us) clock synched on both ends a laser could scan back and forth.  All that is needed is the time of the received beam to calculate the relative angle.  More ideas?
12  Using Arduino / Motors, Mechanics, and Power / Re: Build or buy Galvo for Laser mirrors? on: January 19, 2014, 09:16:18 am
Not sure how to use one.  I tried Google.  Any more links?  What is the lowest cost?
13  Using Arduino / Motors, Mechanics, and Power / Re: Build or buy Galvo for Laser mirrors? on: January 16, 2014, 02:11:32 pm
Has anyone done it with a Stepper Motor?  What type is best?
14  Using Arduino / Motors, Mechanics, and Power / Re: Build or buy Galvo for Laser mirrors? on: January 08, 2014, 11:02:44 pm
A solenoid is all or nothing right?  I have read of a few people using a stepper motor with one coil energized at 50% then you modulate the adjacent one to achieve an analog movement.  This will give you a maximum of one step, which may be enough.  What type of stepper would I use for this?  I am familiar with many steppers, but never for this application.

What is the minimum current you can set for this board?
