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.
