Death of Cookie Monster Robot

Another death on the month of December.  If must not be a good month to be a robot around the Ratliff house.

This time Cookie Monster had just been programmed with updated code.  But his rough prototype design was showing signs of wear and tear.  The www.BudgetRobotics.com BigGripper inside his body broke around the fingers where they meet the push/pull arm attached to the servo horn.  This left the arms not closing all the way and limited movement of the gripper inside.

 
The sensor placement of dual PING sonar units for the eyes on the head and as eyes on the feet were a bit awkward.  People who viewed the robot did not understand why he needed eyes on his feet. The base where the feet mounted was made from Styrofoam board.  It was a quick solution but was starting to bend in spots.  It lasted over a year with limited use.  The goal with Cookie Monster was to build an interesting test bed for some ideas I had; so overall I achieved what I wanted with this robot.

The bad part is, Cookie Monster was so cute and he lasted for nearly two years I'm going to miss the little guy.  For now his parts will live on in other robots.  I believe one day I will have the technology to rebuild him.  :-)
