Question : How can I make a dog, cat or a animal move using hinges?
Answered by : Allen Demers, LEGO Model Designer

You can just build the hinges into the model. Or, instead of hinges, you could use TECHNIC elements such as beams and connector pegs or axles.

To make your model move freely, use connector pegs or axles and attach the legs in one spot. Grey connector pegs will move easier than black connector pegs.

To make your model's joints lock in place, use click hinges. If you opt to use TECHNIC elements instead of hinges, and you don't want your model to move freely, you should connect the legs (or arms) at two points. When using axles, try using the 1x2 brick with the cross-hole instead of the TECHNIC brick to make your model's joints stay put.

Question : How do you put a LEGO engine into a car you've built?
Answered by : Allen Demers, LEGO Model Designer

Automobile engineers know that the easiest way to motorize a car is to begin with a drive train (or motor and axle) and build the car around it. If you were using the newest LEGO motor elements found in the Motor Movers Inventors kit (4094), you would need to leave an area approximately the size of a 4x4x4 brick for the motor, plus an area about the size of a 4x3x3 brick for the drive axle. However, it is really difficult to build a car and then add the engine, so you should always try to build around the engine.

Question : How can I make a LEGO man look as if he is walking?
Answered by : Allen Demers, LEGO Model Designer

Assuming that you are speaking of Minifigures, this is relatively easy task: just push the figure's left leg back and his right leg forward. Then move the right arm back and the left arm forward. The further you move the legs and arms away from the Minifigure's body, the faster the figure will look like he is moving.
