Like most tasks in 3D Studio Max and similar products, rigging robots is easy, if you
know how. Depending on plexity of the robot, some may find it even easier than
rigging a human or animal character. This is because most parts of a robot do not deform
during movement, with the exception of cabling and other flexible parts, so you don’t
have to ‘skin’ it. One of the primary challenges in building a cool robot, which still looks
cool when animated, is creating realistic mechanical joints. Although you may prefer a
simpler look for your robot, during this tutorial we will assume you want to aim for
realism.
The first version of our example robotic leg below is not very realistic however, because it
would collapse like a bone structure without muscles. In the second version, we will add
some robotic ‘muscles’, and the third version will include a hose. Click on the download
links below some of the pictures to download the corresponding scene.
1. A Human Leg
When rigging a human leg, the mesh deforms when the knee bends, pushing vertexes
away from each other on one side and towards each other on the opposite side. This is
plished by using a Skin modifier that binds vertexes of the mesh to the bones. The
colors of the vertexes indicate the weight values which dictate how much influence
moving the joint will have on those vertexes. Red vertexes represent the most rigid parts.
