Rig the character

Have my model done, and then go through the tutorials for rigging character. Start rigging from the top to each legs of my model, first I tried to fix bone with each segment of my model. In that case, I found that there are over 100 bones in all when I finish rigging. Getting trouble for myself actually… I still can not understand what bones mean to the body, how it effects the movement of the body. Maybe it is due to my character which has no bone at all. However, it still needs “bone” to make it move.

Finally, each legs only has 4 legs at most and it make things easier.
