What specifically do you need help with?

Drawing more realistic robots?
You can use the painting tool or you can use any other tool and import the seperate images (jpg, png, gif) into Etoys by simply dragging the image file onto the Etoys project. There is also an interesting project called "The Walkers"http://squeakland.org/showcase/project.jsp?id=7698 which shows animation and the Charaters were drawn using Polygons.

How to animate in Etoys?
Besides "The Walkers" project, there is the "Bouncing Ball Animation" in gallery of projects which shouws how you can animate by iterating through a Holder.
