Lego Round Again (one more time) Using the Science of Lego Mindstorms NXT, this is an exercise in pointlessness. Starting on the SLIDER of LURVE the marble is carried to the KERB OF TRIPPING where its dropped down the SHAFT of DESTINY and onto the RAIL of LEAVES ON THE LINE which takes it to the LIFT of LEVITY which raises the marble to transfer it into the red HOPPER of HAPPINESS where the marble is picked up by CRANE of INCREDULITY which lifts up and rotates 90 degrees to drop it into the HOPPER of HOPE at the top. The marble then rolls down the INCLINE of INEVITABILITY to the TUNNEL of DOOM. Where the SLIDER of LURVE is ready to start the process all over again. The robot uses two NXT Bricks that communicate with each other by Bluetooth, Two light sensors (one RCX and one NXT), five motors (two RCX and three NXT types), three RCX touch sensors, and one RCX rotation sensor.
