Big News: Worlds Smallest Robot

Posted on September 17, 2005

By William Cox & filled under Industry.

I’ll resist the temptation to make a joke about just how ironic it is that such a small thing is such big news, but a group of Dartmouth researchers just recently created, what’s now dubbed, ‘the world’s smallest robot." Whether that’s actually true or not, it’s pretty darn small – measuring 60 x 250 micrometers. [...]

A Review of Robot Builder’s Bonanza

Posted on May 29, 2005

By William Cox & filled under Reviews.

This is a review of Gordon McComb’s book, Robot Builder’s Bonanza. Ever since I started robotics I have searched to the ultimate how-to book. Frankly it just doesn’t exist. Don’t get me wrong, there have been excellent books written, but none of them seem to meet all the right criteria. But, I have found one [...]

Posted on May 29, 2005

By William Cox & filled under Reviews.

A review of the original OOPic. I recently sold one of my Basic Stamp 2s and its carrier board. During this time I had also been hearing a lot about Savage Innovation’s OOPic so, I decided I’d spend my new found $45 dollars and buy one. The OOPic starters package contains one OOPic chip and [...]

Uncovering Robotics – Robots Now

Posted on May 29, 1999

By William Cox & filled under Entertainment.

This article is a brief history of robotics. If the late 1980’s are viewed as the "death" of robotics, then certainly 1988 through about 1992 can be viewed as the "rebirth" of robotics into a stable industry. "From 1987-1992 orders [for robots] increased by 40%. Manufacturers worked hard to improve the robot’s reliability and usefulness. [...]

The RB-Spa-783 is designed for use with 7.2 volt batteries, but can be used with supplies up to 18 volts. If someone uses a supply is more than 12 volts, they will need to add a fan to cool the voltage regulator. In your case, a 12 volt supply should be acceptable. ...

... you both a 6V output and a 5V output? That sounds good. I never thought of that! In my mind, that would be two regulators. Is there one UBEC that supplies both voltages? I ould probably make one as a linear regulator, but some of the switching regulators available look good.
