Motion tracking skeleton at Cedar Gables Inn

Posted by Amanda on 20 October 2015

Forum user Ken constructed a spine-chilling Halloween project that is featured at the Cedar Gables Inn Bed and Breakfast in Napa, California. His project is based on Brandon’s Motion Tracking Skull Halloween prop, but instead of just using a head-turning skull, Ken used a full-scale skeleton body to complete the creepy look.

Just like in Brandon’s example, Ken used two Sharp GP2Y0A60SZ analog distance sensors to detect objects (or humans) and a Micro Maestro servo controller to read the output values from the sensors and control the servo that moves the head. Ken improved on Brandon’s code by returning the skeleton’s head to its starting position after a short delay so the skeleton wouldn’t stare rudely at the inn’s guests.

For more information about Ken’s Halloween project, see his forum post, and if you happen to be in the Napa Valley area this Halloween, stop by the Cedar Gables Inn and check it out in person!

In case you missed it, we have Maestros and Sharp distance sensors on sale right now as part of our Polo-BOO! Halloween Sale. The sale ends in less than two days, so if you want to try doing a project like this, now is the time to get started!

Amanda's line following robot: Newbie

Amanda's line following robot: Newbie

Many of the engineers and robot enthusiasts here at Pololu competed in the LVBots 2015 line following competition. (For house rules and details about how the competition was judged, see the LVBots line following rules page.) Unlike most of my peers this was my first competition at LVBots, so I thought it was fitting to name my robot “Newbie”. Newbie uses a servo to steer the front wheels, creating fluid movements in and out of turns. At least that was the plan; unfortunately, Newbie had complications. Continued…

Maestro Servo Controller Arduino library

It has always been possible to control your Maestro Servo Controller from your Arduino-compatible controller with the Maestro’s serial interface, but now it is easier to get started using our new Arduino library. The library implements (and documents) all of the serial commands available on the Maestro controllers and supports all three sub-protocols (Compact, Pololu, and MiniSSC). Continued…

Severed fingers Halloween prop

Severed fingers Halloween prop

At Halloween parties, it is common to see a punch bowl with one or more eyeballs floating in it and stomach-churning decorations like severed fingers or gelatin worms lining the festive dishes. However, the problem with most of these is that they are motionless and bland. Inspired by Thing, the disembodied hand from The Addams Family, I decided to make a creepy animatronic hand to add some thrill to an otherwise boring table display. Continued…
