  • EasyVR Speech Recognition Module 2.0
    Easy to use, reasonalby accurate. Best deal for the money!
    Review by Ron
    I got the easyVR board and immediately discovered that I needed the development board to really use the board effectively. No problem, another 15 bucks. It took a while to figure out the software but you can do it in an hour or two and have an arduino uno recognizing speech words.
    The main shortcoming of the system is background noise, which is a problem with all speech recognizers. The system would not recognize while I had the window air conditioner running in the room. With the room dead silent the unit is very good. The unit has AGC that will take whatever background noise there is and put it to a reference level. So even fairly low volume background noise will interfere with the recognition.
    A second problem seems to be the AGC adjustment to the voice input. I found that the unit would not recognize after ten minutes or so. After I spoke several words it began recognizing and was then accurate. Seems to take a bit of speech for it to get the volume level correct.
    The last problem I found is that there are some words you cannot program. It refuses to accept words in its internal vocabulary for some reason. This can be a real hassle if you need only a number or two and not the whole range of numbers. Using the entire built-in library of numbers of course uses more of your precious memory! I guess you could go into the source code and chop out the stuff you don't want.
    The supplied software generator is very clever! It will generate a compilable source code with your speech words for the arduino uno for sure, and possibly others. The code generated is heavy so you will want to chop out a lot of it in your final application to save memory, but it gives you an instant runnable program to put in your project. That is really a huge advantage for new programmers! (and for us old hats too!)
    The only complaint I have with the package is the documentation, which is sort of haphazard. If you follow exactly what they show you will get results, but there are a lot of questions you will need to spend time figuring out for yourself.

  • XBee Shield for Arduino
    Easily add XBee functionality to Arduinos
    Review by David
    I didn't realize how useful XBee radios were until I bought an Arduino Fio which has the XBee holder built-in. This XBee Shield is a great way to add the same functionality to other Arduinos,,, I've used it successfuly with the Uno and Bluno. I own several different products from this manufacturer (IteadStudio) and am satisfied with their quality.

  • Bluefruit EZ-Key Bluetooth HID Keyboard Controller v1.2
    EZ-Key with iPad and OnSong app ...
    Review by Claude
    Follow-up: Took less that 10 minutes to setup EZ-Key to work as a pedal controller for the song/music management app (OnSong) on the iPad. Now I can control the song/music scroll speed, and start/stop with foot pedals so I no longer have to stop strumming to advance/scroll the page. EZ-Key, an inexpensive way to DIY Bluetooth music pedals.

Robot Construction Kits

Posted on April 23, 2014

By Coleman Benson & filled under GoRobotics >> Education, Robotics Projects & Kits, Where to Start.

Robot Construction Kits can be distinguished from normal robot kits since they use modular parts and allow you to assemble different robots using the same parts. A robot kit on the other hand only allows you to build one robot. Robot construction kits are a great investment because they tend to include everything you need [...]

Invasion of the Telepresence Robots!

Posted on December 02, 2013

By Mario Tremblay & filled under Telepresence.

A robot invasion doesn’t have to be scary, though it’s important to know that it isn’t science fiction anymore. When the film 2001 A Space Odyssey came out in 1968, Dr Floyd’s casual use of a teleconference robot during a space station layover was as much science fiction as the “space plane” he took to get [...]

Can you provide an image or two of the setup? The blue LEDs are only aesthetic, and the others are for power and communication.
There is sample code loaded on the board, but you should really upload your own.

Sorry, I don't have enough information to give a clue here. Information, like what robot or the like, what servos, what software was loaded on the botboarduino. Are you following a tutorial, if so, which one and what step are you up to.

Hi, After doing a calibration for the SSC-32 the PS2 works and we can hear the beeps but the servos do not move.
Any help or suggestions would be greatly appreciated.
I have the BotBoarduino connected to the SSC-32 board
I've included images of both boards
Thanks

I was under the impression that the tunnel was filled, sorry.
But even so, you might have issues with signals since there are turns / obstructions etc.
We cannot tell how far you will be able to go with either the video or control signal without testing in the environment.
