Dragonoid

Dragonoid was part of a school project that involved building a 12cm x 12cm x 12cm cube out of wood then turning it into something. I decided to create a robotic dragon. As you can see, construction paper was used as well as Lego. Luckily, the colours of the paper and green bricks were close.

Dragonoid was originally designed to be able to look left to right, raise its arms in terror, and open its mouth. I wasn't able to add the mouth function as I ended up running out of time (school project).

The inside of Dragonoid is a structure that reaches up about halfway up the cube, and the colours don't match. The construction paper covered the inside up so the colours didn't really matter. I just didn't use green, as I needed as much green as possible for the arms and head. On top of the structure is a motor connected to a gear train that controls the arms. Strength wasn't a priority since the arms would raise in small bursts.

The arms are plate and bricks built together, with a cylinder at the shoulder area, which connects to an axle that is powered by the motor inside the dragon. the arms are mirror images of eachother, and had to be redesigned a few times to cope with the green plates available.

The head was based on the Insectosaur head. I had it lying around, so I quickly made a motorized version of it. A motor is inside the head that is attached to a bevel gear, which is connected to a 40-tooth gear that is on it's side. The 40-tooth gear is locked in place with the help of some beams, it can't rotate. But when the motor inside the heard rotates, the bevel gear drives around the 40-tooth gear, and causes the head to turn.

The feet and belly are also made out of construction paper; you can see I'm not the greatest with scissors and paper.

Dragonoid is controlled by a remote control, which is 5 pieces. 1 NXT brick. 1 wire. 1 IR Link Sensor. 1 pin. And 1 more pin. The buttons are used to activate Dragonoid. Left=Turn Head and Orange=Roar
