Introduction
This week, we modelled the upper arm and created another piston to connect it with the forearm.
Modelling the Upper Arm

Basic Volumes
In order to model the upper arm, we created basic volumes (cylinders) to resemble the bone structure.

Forearm & Upper Arm
On top of the bone structure, we modelled more cylinders and edited the vertex points to create the rough shape of the forearm and upperarm.
Adding Controllers
Controllers
We added some controllers to our mechanical arm by creating some NURBS curves.
These controllers enabled us to control our mechanical arm more effectively.
Modelling a Piston
Creating a Piston
We created another piston in order to connect the upper arm and forearm.
We used locators and constraints to attach the movement of the arm to the piston.
