Mobile Pneumatic Multi Arm V4

Young humanoid wanted to continue his MPMA (V1, V2, V3) series - but this time, he wanted to use a real mechanical multiplexor.  The multiplexor, in theory, was quite simple.  Two motors moved up and down on a chassis of beams.  This actuation was powered by the third NXT motor.  The motors could move into three positions.  On each position, the sixteen-tooth gears on the motors meshed with the sixteen-tooth gears on the sides.  Thus, the robot could use a total of six functions from three motors, although only a set of two functions could be driven at any one time.  The first set drove the treads, giving MPMA V4 the most maneuverable drive base in the series.  The second set drove two pneumatic switches - one for the arm's cylinder, one for the claw's cylinder.  The final set drove the arm rotation on one output and pneumatic pumps on the other.  MPMA V4 is considered by young humanoid to be the best robot in the series to date.

Mother's Day 2012 Project

Young humanoid wanted to build a project for mother humanoid, and decided to build a scissor lift.  The robot rode on tracks forward, before raising its scissor lift while playing a song.  Young humanoid left out one side of the top of the lift, allowing a message to effectively "pop up" so mother humanoid could easily read it.  The robot would then wait a few seconds, lower the lift, and then back up.

Orange Car

Orange car was the result of young humanoid's want to enter an unofficial NXT building challenge with the theme of vehicles.  Young humanoid used three motors - two to power a rear differential, the last in a complex gear system that steered the front wheels.  The entire car was remotely operated through a second NXT on a LEGO handlebars construction, inspired by Per_and_Emil's project Rally simulator - HAP 2.0.  Tilting the handlebars forward, reverse and sideways would result in proportional control of the operation of the car for speed and turning. 

Experimental Walker

Young humanoid decided one day to implement a new walking mechanism, inspired partially by teenager101's project RC Ferarri Enzo (in white).  The resulting robot was an articulated quadruped, that, unfortunately, had slipping gears when turning with too much resistance.

RIS 2.0 Class Bot

Having one of his NXTs occupied in his Vending Machine III, young humanoid decided to construct a simple RIS 2.0 robot that the children in his class could construct with his step-by-step instructions and guidance. 

NXT Class Bot

Young humanoid was requested to formulate a robotics class for children.  In order to make it hands-on, he revisited his Simple Robot as a simplistic platform which the children could build themselves along with his step-by-step instructions and guidance.  However, he modified the castor wheel.

RIS 2.0 Train Bot

With Christmas approaching, young humanoid wanted to build a machine that navigated around the Christmas tree on a wooden track.  The result was the very simple RIS 2.0 Train Bot, which was powered by a single motor.  Young humanoid ended up having to add a rubber band to one of its drive wheels to supplement much-needed traction for getting around rough parts in the twisting track.
