It's not poseable (as is) and all the legs are differnt angles and I'm not sure how Bryce would handle that. If it's modeled so it can be ungrouped into separate parts it should be possible to pose/animate it. It'll be a lot of work and getting all the pivot points set right will be a pain it the butt. Basically place bryce cylinders or whatever in the right spots and set them as parents to the parts they control. Then set the bryce objects being used as the controls to hidden so they don't show in the render.
