Aragosta
Aragosta (means "Lobster") was designed to attend a robotic Mini-Sumo challenge
during a public exhibition in Milan. See the
Events - International Toy Fair
section of the
ItLUG site
if you want to find out some more details about that event and the other
competitors.
Mini-Sumo is a variant of the robotic Sumo that our Italian Mindstorms group
defined to be limited to RIS parts only (a single RIS). As color changes were
allowed, I made Aragosta out of a yellow-black-gray version of the standard RIS
1.0 equipment.
Aragosta was built using a very simple architecture: differential drive with
1:25 ratio, a light sensor to detect the border of the field, two antennas to
locate the opponent.
This was my first robot programmed with
pbForth.
Learning Forth was a sort of challenge in the challenge, but I must admit it's
been fun!
Side view. I tried and used as many parts as possible to give Aragosta the
maximum weight. This is true also for all the gears placed behind the RCX, and
for most of the other pieces.
The resulting look is a bit weird...:-)
