However, when I looked up the other parts I would need, I saw that the solenoids they were specifying on the Makezine.com website were $18 each. That's too much for my wallet.
I knew a source for a similar solenoid for only $1.50 each. Thus, econoSpazzi was born.
Here's the site for the original Spazzi project on Makezine.com. I bought my solenoids from allelectronics.com. They are rated for 24V DC, but I found that after I cut the included spring to size, they worked fine at 10-12V DC.
SpurtBot

These instructions are for building a very simple version of a line following robot, based on the SpurtBot design above. Thanks to Hartmut from Rostock University for his support in creating this design.

This simple robot handles basic navigation and is armed with a bass drumstick thumper at the rear and a high hat drumstick on his left side. His front bumper switch is used for collision detection. He currently has three drumbeats he alternates between.
GRAB-E

GRAB-E was inspired by the film WALL-E, but he's not really much like the titular character. GRAB-E is a good platform for expansion, and there's a lot more I hope to do with him.

One flower is complete, with touch sensor and electromechanical fly accessory. I marked her as complete, although she may eventually have two to four flowers each controlled by two servos. One servo swivels the stem while the other opens and closes the mouth.
The hairs on the flower are connected as a touch sensor, so she knows to close when a yummy snack is in her grasp.
