My second exercise during which I studied most of Blender modelling and animation.
It is Fan Art of Sony's AIBO robot dog (ERS-7) model made with help of reference photos.
Rigged (basic rigging – as this is robot OBJECT-to-Bone parenting used), IK limitations to rotation of head and legs applied (+tail).
This is fan art. AIBO trademark and it's conceptual design are property of respective Sony Corp.
