"Muzio Scevola" is a Puma 560 fitted with a small gripper equipped
with a pair of ultrasonic transducers to be used in horizontal and vertical
navigation.
On the gripper there is a pair of light beams
aligned with the z-sonar. Sonars and light beams are
controlled by a self-contained 68HC11-based miniboard which provides
their information sampled at 50 Hz.
An industrial machine vision
system (DATALOGIC DVS 1000) operates up to two B/W cameras (stationary
and on-board). The vision system is based on a 20 MIPS Hitachi DSP and
is linked through a parallel, digital connection to the the main
robot control system.
The latter consists of a VME-based microSPARC FORCE-3CE CPU which runs
Solaris 2.x hosting RCCL. This system is interfaced via parallel I/O to
a Unimation Mark II Puma controller, and via RS232 to the 68HC11 board.
"Giulio Cesare" is a Nomadic Technologies Nomad200 mobile robot
equipped with four sensor modules including tactile, infrared, ultrasonic,
and a CCD camera on a pan-tilt unit. The robot has on-board computers for
sensor and motor control as well as a 486DX/2 IBM-compatible computer,
connected to our LAN by a radio Ethernet system.
"Giulio Cesare" is programmed with an integrated software package including
a graphical robot simulator; the package facilitates the development of (C-Lisp)
robot program, running both on simulator
and on-board systems.
"Nerone" is a small mobile robot built by M. Limoni and A. Melotti.
It is based on a MC68HC16Z and it is equipped with 6 infrared
sensors and a bumper ring.
A recent addition is an electromagnet capable of gripping a metal
plate to be used as a marker.
