A few years ago Charles Guan was a teacher's assistant in MIT's 2.007 introductory design and manufacturing class. To help out his fellow students he made a guide to building robots quickly and efficiently. Now he has expanded the original guide, retitled it How to Build your Everything Really Really Fast (HTBYERRF) and published it on Instructables, available for anyone wishing to progress from the "zip ties and duct tape" stage of building things.

Sculptural Robotics are whimsical "artificial lifeforms and other curious artifacts," mostly created from hard drive components, solar engines, and brass. Artist Dan Roe also links to Arthur Ganson's Machines, a portfolio of wonderful mechanical creations. Ganson in turn links to Tim Prentice's awesome Kinetic Sculptures - all are fun examples of when technology, machines, and art collide.
Lawrence Northey's portfolio of robot sculptures. Meet the charming Teen Tokyo, the elegant Robot Queen and her entourage, and others in a delightful cast of characters. The artist creates some very cool rayguns too! Northey's works are in the spirit of Clayton Bailey, the robot artist extraodinaire. (via La Petite Claudine)
