Constraints and inverse kinematics were added to the rig/armature to aid in movement or animations. The blend file contains 25 mesh objects for the robotic arm model; 1 rig/armature with 26 bones; 2 point light with 1 camera; and 6 mesh objects for the custom bone shapes of the rig/armature(Note:the mesh objects used for the bones' shapes were not added to the vertex and polygon count). The Model also has 4 materials with no textures and no UV maps.
