Alternative to Xtion 3D sensor?

Hi,

For my new robot I was planning to use popular Xtion depth sensor. Even got one. I am really like it because it is smaller than Kinnect, does net require separate power supply and well supported by OpenNI on Linux. Unfortunately, there are indications that it is discontinued by Asus.

Fast vision sensor for Arduino

It does 50 frames per second and they are "giving it all away" so to speak.  Software, schematics, board layout.... worth a look.   

Robot Vision

Good afternoon all,

I was wondering if any of you had seen the following, as I'd be very interested in your thoughts and opinions.

Thankyou,

Stereoscopic vision help

Hi, I am willing to built a stereoscopic navigation system (which will have 2 paralel webcams to capture images every X second and compare images with each other to find depth)  just for fun and coding challenge(more challenge actually) but i have no idea how to do that, i am searching and reading sources with all kind. however since i have no idea where to start more i read it makes me feel more confused and i cannot find a complete guide to follow.

Good Robot Controller?

Ok I am planning on building a "small" humanoid robot that can has computer vision and can do many tasks. I am planning on using a small onboard computer to do all the processing so that it can be autonomous and reduce the need to have another computer on for it to work. Anyway I am looking for a small, not expensive, and easy to use, some what powerfull small computer or single board computer that has usb ports,can run off a small battery and can run lunix. I am thankful for all suggestions.

Computer On Wheels Controller

Hi guys,
 
 
 
Since last week, I've been learning c++ and openFrameworks and creating a application to control any robot with a computer on it or, at least connected to one by someway.
 
It is supposed to be simple to implement and use.
You just need to run the application and program your robot to read the following chars and act corresponding to them:
  • 'w' to move forward;
  • 's' to mo

Suggestions for TheBox

Hi,

Lately, I've been creating computer vision applications for my robot TheBox

I've created a color tracker, a motion detector and a wall avoider application.

But now I ran out of ideas. 

 

So, can you give me some cool ideas to make other applications? :)

Well, this is probably the simplest robot I've ever made. It is just this event's robot mounted in a old IBM box. I've built it just to serve as a testing platform … Read more

XMOS based XC1 robot which tracks your hand

Just happened to find this on youtube. Is not by me, but is a cute video none the less so I thought I would share it:

Cute little XMOS XC1 robot

Slightly more advanced LDR eye

Read this history first, if you have an hour to kill.

The challenge: make your bot rove around your house. Use no active beacons. Use observations by your bot only. Now, does your bot know where it is?

One possible answer: an eye and a brain.

Room Recognition

Each room in the house has a unique lighting situation. A simple eye that looks around in eight directions would "see" a pattern of light and dark segments. Each cell is connected to one ADC on your uC.

Rudimentary LDR eye

Old idea rekindled

This idea about very basic robot vision haunted me ever since I first saw AmandaLDR. Even before it was named after a canine. It's somewhat inspired by the evolution of the first eyes in nature: just a bunch of light sensitive cells on your rump.

Night vision camera

Hi, I've been thinking on building a night and day vision camera. I think its very straight forward, but I just wanted to have a look at your personal opinions before going any furtherer.

The idea is very simple: As you probably all know, digital cameras are able to "see" the visible spectrum, but also, some frequencies higher (I think), and lower. You can try this by pointing with a remote control to your camera, you will see a white light.
