Body second iteration

After the success of the first iteration of the mechanical design I have now moved on to scaling the animatronic up to it's intended size.

During this second prototype I changed the type of motor from steppers to worm screw geared DC motors for the body section. These may not be as accurate but they have a far greater holding torque and consume less current. Because of this new addition I redesigned both the axle base and the axle mount show above and below.

I attempted to increase the size of the head though after stress testing the weight I knew I had to return to its original diameter of 20 cm.

In the photo above you can see a four inch "Lazy Susan" bearing sandwiched between the two halves of the body and platform. This bearing givs the two halves stability and a smooth turning action. Though due to the bearing's construction I will have to replace it with a sturdier model.

Above is the large scale platform test.

Next I will be working on the "face", correcting the instability of the body and sourcing the appropriate batteries.
