PLEASE NOTE: Each OmniBot Pack requires the use of two Linkbot-I robots (not included). Therefore, if you are purchasing OmniBot Packs to go along with Linkbot Bundles, the following quantities are recommended:
One OmniBot Pack for each two Linkbot Super Kits ordered
Two OmniBot Packs (or one 2-OmniBot Pack Bundle) for each 4 Linkbot Bundle ordered
Four OmniBot Packs (or one 4-OmniBot Pack Bundle) for each 8 Linkbot Bundle ordered
Eight OmniBot Packs (or one 8-OmniBot Pack Bundle) for each 16 Linkbot Bundle ordered
 
The OmniBot Pack turns two Linkbot-I into a 4-wheeled OmniBot that can move in all directions!  It not only can move forwards and backwards, make turns and circular motion, but also move sideways and diagonally. The Pen Connector and Pen Adapter add drawing capabilities to the OmniBot with endless possibilities for creating beautiful artwork using nearly any off-the-shelf markers and pencils.
