HEXBUG Hexbug Spider colors vary
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
>Huh? You can buy line-following robot kits on Amazon for $30, and there are even cheaper ones out there.
There is the hexbug spider which makes a nice, hackable beginner platform (http://www.amazon.com/HEXBUG-Hexbug-Spider-colors-vary/dp/B0...) with the addition of an arduino nano.
The kilobots are also cool (http://www.eecs.harvard.edu/ssr/projects/progSA/kilobot.html), and an even smaller, cheaper robot (http://www.hizook.com/blog/2011/09/08/infrared-remote-contro...) using the same principle of locomotion.
