Ping Radar

I have a question about the PING radar. Is there a way to reverse the display swing to match the same direction the servo is going? I looked for a servo reverse with no luck. I just recieved my EZ-B today. It is so easy to setup the hardware. Thanks DJ Sures!!!! Cadmanj

Speech Recognition

Hello, I just got my new computer and I am finally running Windows 7. To my dismay I spent the entire day and I can't get speech recognition to work. I have read all the turorials and searched and read everything on the forum to no avail. Language, default, Windows SR off, tried everything. Any further suggestions would be greatly appreciated.

Learning To Use The EZ-B

OK, so far I've gotten my omnibot, EZ-B, servos, and camera. I've accomplished speech control with the head servo, and arm movment.

Now I'd like to learn how to set...

Concise EZ-Robot Post By Servo Magazine

I was browsing the other day and found this great Servo Magazine post about the EZ-Robot project. It's pretty much mostly copy and pasted text from the site but it's put together nicely.

A Line Of Code Equivalent To Servo Release?

Hi, after the servo moves, sometimes, i get a constant buzz from the servo, like the motor is still trying to lock and stay in 1 place. the servo already moved to the desire position. But to get rid of the buzz sound, i press "Release" button on the ARC Seervo control box. This stops the buzzing sound from the servo. Is there a scripting...
