delfim project
delfim is a
small autonomous catamaran. It has been designed as a prototype vehicle to
proof test the concept of an autonomous surface craft capable of working in
close cooperation with an autonomous underwater vehicle.
(see asimov project)
delfim is
3.5 meter long and 2.0 meter wide and is propelled by two electric motors.
Energy is stored in six 12V-55Ah lead acid batteries for propulsion and four
12V-12Ah lead acid batteries for payload (computers and sensors). Basic
sensores to be installed on board the Catamaran are a DGPS, an attitude sensor
and an echosounder.
One of delfim's
main features is it's central body, the "torpedo". We plan to install all sensitive
acoustic transducers there in order to avoid the effects of air bubbles that
are always present close to the hulls and close to the surface. Electrical
cables run inside the wing that holds the torpedo and are connected to the
electronics installed inside the hulls.
