So I am back in the shop after churning away on my computer doing CAD and researching and sourcing some specialty pieces for my next project. I was attempting to avoid the use of any electrical bits, but it seemed to be the most plausible path to build some reliability into the project. So at the ripe old age of " I can learn anything - I think! I am setting out to use a little electronics, (Arduino), plus some servos and motors to accomplish things. This decision was made since my design incorporates a requirement for actuators to go up inside the leg of an animal. I'll keep that a mystery for a bit just for fun.
The photo below shows the leg construction. The design uses a construction system not unlike building plane or boat models. There will be a structural skin on the legs, shown on two at this point, with a later covering of another type. This exoskeleton will provide the required strength. The skin is 1/32nd birch plywood. After gluing one edge of the plywood onto the frame and letting it harden, I glued the remainder on with an overlap. The elastics provide clamp force until the glue dries. In the meantime I'm cutting out ribs!
More to come!
