Robot Portals

MachineBrain

Web Site: http://www.machinebrain.com/

This site has lots of great links to other sites (in categories such as General Robotics, Fighting Robots, Robot Reference), as well as robot technology news, and even a free classifieds section.

Robot Café

Web Site: http://www.robotcafe.com/

This site is dedicated to all those who "live, eat, breath...robots." Please, people, if you start dining on computer chips and shoving nuts and bolts up your nose, you've got something beyond an exciting hobby interest that you need to have a professional take a look at! The two main features of this site are an excellent directory of online robot resources and a gallery of robots with basic information on each bot and links to the robot builder's Web site (if there is one).
Anyone can register on the site and post bots.

Robots.Net

Web Site: http://www.robots.net/

Probably the most popular robot portal, Robots.Net is frequently updated with cutting-edge tech news, product reviews, how-to articles, and directory listings. It also has a large gallery of robot projects. Its "Robot of the Day" column on the front page is a great way to see what the gallery has to offer.

TechGeek

Web Site: www.techgeek.com

This is another robot site worth regular visits. It offers news, reviews, a really nice project section detailing site members' building efforts, and robot club listings. There is also a big list of resources.
