Running a bit late. Sorry about that. Hope I still count.
Had major trouble with Parent constraining objects to the hands. Afer some tries I though I had figured it out,... I worked around it for this project though.

Basically my robot is a pencil sharpner that can clip small stuff on its back. Drives around to help pencils in need

here is a breakdown of my character:

arms
combination of polygons, NURBS and Subdivs (subdiv pads and fingertips converted from polygons). The whole arm and all fingers are setup with IK and with SDK.

wheel
Tire, rim and suspensions are made up of NURBS (no convertion used). Can't go wrong with Good Year!
(Profile on the tire is not a texture)
Used a math. expression to rotate the wheel is it moves forth and back (not foolproof yet). Suspension is SDK.

eyes
Eyelids, cornea, eyeballs, pupil, iris all seperate NURBS (no convertion used). Eyelids, eyeballs and iris are animated with SDK. Eyes are aim constrained. Texture of circuitboard on the iris.

body shell
completly made up of NURBS (no convertion used). The 2 halfs can rotate and bounce using SDK

clips
Made from polygons and some NURBS.

Misc.
Pencils are made from NURBS and the eraser NURBS converted from polygons.
Used 3 directional lights to creat ambient (my version of 3 point lighting) and 2 spotlights for shadows and highlights. Did something wrong in the Light Linking,so Some lights don't shine on objects that should.



The animation can be found here. (in an hour from when I post this, slow internet connection). In all haste making this animation at the last minute, it could have been a lot better (no sound, here and there a hand drops thru the floor etc.). But i hope u still enjoy it. If not ... let me know why

Added note:
Here u can see what textures I've used in the scene.
