NXT Ultra Pinball Machine III

The third installment of his NXT Pinball Machine series, this project provided some unique challenges for young humanoid.  Firstly, he wanted to build it all out of LEGO (or DUPLO) elements. Secondly, he wanted to make a ball launcher mechanism and realistic flippers, inspired by legothom's project Space Pinball and another in the book Building Robots with LLEGO MINDSTORMS by Ferrari, Ferrari and Hempel.  A brace under the playing board provided the means with which to hold the bricks in place, as well as the machine's feet.  Young humanoid implemented two scoring systems - the touch sensor and top and the light sensor to the left.  A RIS light sensor detected when the ball had escaped through the flippers and entered the launcher again.  Young humanoid wrote a NXC program for the machine, which ended up working rather well.
