Here is an almost completed robotic arm for the modeling/animation work I am planning to do. These are the arms in regular arm mode, where many of the segments are locked down so that it will behave similarly to the way a person's arm behaves. In the animation, most of the time the arms will be articulated in this way. The "elbow" needed 2 segments to get the full range of bending, each segment only has about 60 degrees of bend before polygon overlap starts to get visible, so using 2 segments for the elbow made more sense. Oh, and if the angle on the shoulder looks weird, it's because it is a 45 degree bend. That way the shoulder can move to any needed position without requiring the double segment joint of the elbow. Ignore the fingers for now, they are only place-holders at this time until I have the chance to model fully articulating ones. Ugh. Why did I have to like this design so much? Just because I want the arms to have a "squid" mode... Setting up the object hierarchy and IK for this is going to be a real pain in the ass. Oh well. Hopefully the end result will be very worth it. Feedback/critique is very welcome.
