I'm working on a project on landmark based navigation, we use:

0)  A robot from Nomadic Tech. (based here in Palo Alto) which has three
rings of sensors i) 16 sonars ii) 16 infrared sensors iii) 16 fairly useless
bumpers..  the only processing done on board is control of motors and sense
cycles and communication via the radio-modem

1)  I'm using a mac IIci because basically that's what was available and I
think until recently, that was the only platform for which they'd written
an interface for.  Until now, processing power hasn't really been an issue.

2)  The interface and simulator are both written to run in Allegro Common
Lisp, which is nice.  The on board stuff for the robot is, as far as I know
(pardon my ignorance, but I haven't had to mess with it yet), C for the
6811s which written, compiled, and downloaded from any old PC with the
proper connections.

hope this helps, If you want, I can get more technical specs concerning
on board processing, sonar and IR, etc....

Dear Willie:

We have two robots at Alcatel Alsthom Recherche (AAR):

The first one is a robot for indoor environment and has two motorized
wheels and is equipped with a ring of 16 ultrasonic sensors and laser
stripe range finder. This work focusses on world modeling (using
sonars), navigation (obstacle avoidance and path planning), and
mission planning.

The second one is a robot for outdoor environment and has four
tiltable tracks robot equipped with force sensors, an inertial
reference system, and a laser-stripe range finder. This robot is
either teleoperated or autonomous and thus it is able to model the
terrain (with the laser-stripe) and plan a trajectory (by modifying
the orientation of the tracks).

Both Robots software run on a VME multi-processor hardware (up to 10
boards) supporting a real-time operating system (VxWorks). 

Softwares are first developed on SPARC II workstations connected to
Ethernet ( workstations run X windows and MOTIF) and are then
downloaded into robots.

If you need more information, please do not hesitate to contact me

Cheers

0) We have a couple of robots built on RWI bases with Denning sonar
modules; the on-board computation is done on New Micros Inc.
68HC11-based single-board computers, which have a FORTH kernal in ROM.

1) We use SUN sparc 1's and 2's networked with ethernet (TCP/IP)

2) We edit with GNU emacs, write graphical stuff with Xlib and Motif.

3) We use FORTH on the robot, and C++ on the workstations.

-----------

We have another robot under development - here's my best guesses about
that:

0) The robot is based on a much larger RWI base (about 26 in.
diameter, 1200 W/hrs of battery power).  The on-board computer will be
a Moto. 147 - a 68030-based VME board with lots of interface,
including ethernet.  This will be running OS-9 with realtime
extensions.

1) same workstations

2) Same environment on workstations, OS-9 environment on robot

3) We'll use C or C++ on the robot instead of FORTH

This walking robot has been designed for space station trusses, to both
travel on it, and manipulate objects (e.g. other parts of the
truss structure, satellites, or tools required by astronauts.)

VMEbus-based system, with several Ironics MC68020 and MC68030 single
board computers (SBC).  Each SBC is running the Chimera II Real-Time
Operating System (finger 'chimera@cmu.edu' for more info on it).
The system also contains ADCs, DACs, and PIOs for I/O.  The VME
system is hosted by a Sun workstation, on which development is
performed, using standard Sun tools (e.g. cc, dbx, X or Sunview, etc.)
and the Chimera II support tools.  Communication between the Sun
and VME system is through BIT3 VME-to-VME adaptor.  The robot
is tethered, hence does not carry the computer on board.

Multiple CPUs are used to get additional performance.  All interprocessor
communication is over the VME backplane and processor transparent, 
and the capabilities are provided by Chimera II.

  The short answer is that we use about 70% Symbolics, 15% RS/6000;
5% DOS machines of various flavors, and 10% Suns.  Over time, the RS6000s
will increase.  We have (as you know) 4 RWI 12" bases, and the Esched Scorbot
III arm. We have since acquired a Zebra Zero Gravity arm, specially lengthened
to our specifications.

   We use Lisp, except for Alberto, and the vision people, who use C.
Jon has lately been trying to use Microsoft Small C on one of the DOS machines.
He doesn't like its lack of debugger, or lack of decent debugger.

  On the RS6000, we use Lucid lisp, with CLOS and CLIM. It works OK for me,
but Jon does a lot of array-consing, and the garbage collector seems to have
a bug where it runs out of space eventually. (I don't see this in my work,
though.) We are still running the beta-test version they sent us last summer;
they say there'll be a new, real production version of Lucid coming in a few
weeks.  The debugger for this Lisp is OK but not great by any means.  There is
one guy around here who has Allegro; he says the debugger is really nice, but
still only about 75% of what Genera provides.  CLOS seems to have no problems
of any kind. I like CLIM a lot, especially the colors (!) and 8-bit gray
scale (Symbolics' displays have to dither to show gray), but we still have
version 1.0, which I think has some flaky (repeatable, but stupid) behavior
which I expect will be ironed out in the next release of CLIM (1.1? 2.0?).

  We of course use X-windows for everything on the AIX or UNIX machines.
Mostly use Motif (mwm); Alberto uses twm, if I remember correctly.  The
DOS machines mostly do NOT run windows, but there are 2 here that do.
(We have 286 and 386 processors; no 486's so far. All stationary. On board
the robots, only Jon's 68HC11 network, coupled by radio (ARLAN is the manu-
facturer) modems to the Symbolicses.

   Networking: Symbolics' Chaosnet, Ethernet, and PC token-ring LAN. TCP/IP,
NFS-mounting between all machines except PCs.

   We do not have VxWorks, OS-9, CONDOR, or anything like that.

   The C people on the RS6000 use something called SabreC, which they claim
is great in all respects.

    Alberto uses Khoros for image-munging, and another tool with a name like
XRS. He likes them.

   For figure document preparation, there's I-DRAW, which might be available
on both UNIX and AIX, which creates just wonderful color foils, and I gather
it's not hard to run.


   Hope this will do. Feel free to ask questions on anything I've forgotten
to address.

-Norm

   I meant to mention in my previous note that the typical way to run Lisp
under AIX is to run it in a GnuEmacs buffer. With Lucid, there is no partic-
ular synergy; with Allegro, there is the ILISP package (which I think was
written at CMU), which is a suite of GnuEmacs-lisp routines that tightly
couple the editor to the lisp, so that you can do "meta-point", for instance,
and many more good things. I implemented a couple of these sorts of things
myself to work with Lucid, but didn't achieve the same level of performance,
because I was just passing text strings to *standard-input*, and Lisp read
them whenever it felt like it. The ILISP system uses a TCPIP "socket", and
starts a Lisp process which is dedicated to reading it; this process is
asynchronous with the main lisp process or processes.

Willie,

Sorry for the delay in responding.  I'll answer regarding my two robot
projects: the Ambler Planetary Rover and the Mobile Manipulator.
If you'd like, I could forward this on to other projects at CMU (NavLab,
HMMWV, Tessalator).

I. AMBLER: 
   0) A brief description of your robot configuration.
Ambler is a six-legged robot designed for autonomously walking across rugged
terrain, such as that found on Mars.  The Ambler features orthogonal legs
(RPP mechanisms) that decouple horizontal and vertical motions.  It has a
novel *circulating gait*, in which trailing legs recover through a central
body, past the other legs, to become the new leading leg.  The Ambler uses
a scanning laser rangefinder to provide 3D terrain maps, and six-axis force
sensors in each foot to indicate terrain contact.  The Ambler also has
incremental and absolute encoders on each joint, and two inclinometers to
indicate tilt and roll of the machine.

   1) Type of workstations (e.g. SUN, Silicon Graphics, IBM
      RS6000, HP, IBM PC/XT/AT/286/386/486, Macintosh, ...)
      used and why.  If you more than one workstation, please say how
      they are networked (e.g. ethernet with TCP/IP, Appletalk,...)
The Ambler uses 9 Creonics motion control boards for low-level servo
control.  The real-time controller is implemented using two Motorola CPU
boards that communicate via a VME backplane.  Perception and planning
software run on two on-board Sun SPARC II workstations, which communicate
with each other and the controller via thin-wire Ethernet and TCP/IP.  The
perception software communicates with the laser scanner via an S-bus to
VME-bus converter.  The various hardware choices were made mainly for
reasons of availability and compatibility with our existing development
environment.  We also make use of two simulators -- a 2D X-based simulator,
that runs on Sun workstations, and a 3D simulator running on a Silicon
Graphics IRIS workstation.

   2) The development environment used for both the workstation and
      the on-board robot  e.g. GNU software, MPW (for the
      Mac), X windows, MOTIF, VxWorks, CLIM, ...  
Operating system is standard Sun Unix for the perception and planning
software, VxWorks for the real-time controller.  User interface is done
with a combination of X and Motif.  Systems integration uses the home-grown
Task Control Architecture (TCA), a message-based system for passing data
and control information between distributed processes.  Communication
through TCA is via TCP/IP, and the architecture runs on Sun, NeXT, and RT
machines. 

   3) Languages used: C, LISP, Prolog, CLOS, ...
Development uses C exclusively.



II. Mobile Manipulator
   0) A brief description of your robot configuration.
The Mobile Manipulator project is based on a HERO 2000, which is a
2-wheeled robot with manipulator arm and gripper.  The sensors include
scanning sonar, fixed base-mounted sonar, and a pointable wrist-mounted
sonar.  There is a BW camera mounted on the robot plus a ceiling-mounted
camera for use within the laboratory.  The tasks of the Mobile Manipulator
include collecting cups from the lab floor, retrieving and delivering
printer output, recharging itself when necessary, and exploring its
surroundings.

   1) Type of workstations (e.g. SUN, Silicon Graphics, IBM
      RS6000, HP, IBM PC/XT/AT/286/386/486, Macintosh, ...)
      used and why.  If you more than one workstation, please say how
      they are networked (e.g. ethernet with TCP/IP, Appletalk,...)
The on-board processors of the HERO are Z8088s (I think).  These are
programmed to execute guarded move commands and to provide a higher-level
interface to the off-board system.  The off-board system uses standard Sun
workstations, mostly IPCs and ELCs.  We also have a speech interface to the
robot operating on a NeXT workstation.  Communications to/from the robot is
via a 9600 baud radio link.  Camera images from the robot are transmitted
via a standard Rabbit video transmitter, and digitized on a Matrox board.

   2) The development environment used for both the workstation and
      the on-board robot  e.g. GNU software, MPW (for the
      Mac), X windows, MOTIF, VxWorks, CLIM, ...  
Development is using standard Sun Unix.  User interface is via X windows
and text-based entry.  Allegro CommonLisp is used for the LISP-based
processes; the CC compiler for C-Based processes.  Systems integration of
the distributed processes is via the Task Control Architecture, which is
used to connect both the LISP and C processes.

   3) Languages used: C, LISP, Prolog, CLOS, ...
On-board software development is in HERO-Basic (sigh).  Off-board
development is in C (for the controller and perception software) and LISP
(for the planning and user-interface software).

Willie,

   I would like to do an informal survey of the development enviroments
   being used out there.  The things that I would be interested in are:

      0) A brief description of your robot configuration.

A Denning MRV-1 mobile robot platform, 
  -The base is synchro drive 
  -An optional head platform is installed with an independent turn axis
  -upper ring of 24 sonars at 15degree separation about 2.5 feet off the floor
  -Lower ring of 6 sonars ~eq spaced with baffels about 5 inches off the floor
  -Pitch and roll clinometers
  -IR Beacon reading system
  -Laser target reading system
  -Base processor is 68000 which communicates to the robot's subsystems
  -Additional 100 Amp Hr 24 volt power and necessary Dc-DC converters 
   to supply power to an on-board MacQuadra 
  
-  We also have a PRISM real time sterio vision system which can be mounted on
the robot and controlled to provide additional sensory information.

      1) Type of workstations (e.g. SUN, Silicon Graphics, IBM
	 RS6000, HP, IBM PC/XT/AT/286/386/486, Macintosh, ...)
	 used and why.  If you more than one workstation, please say how
	 they are networked (e.g. ethernet with TCP/IP, Appletalk,...)

The MacQuadra which is on-board uses RS232 ports to command and read the
sensors and actuators leaving the lowlevel control to the periphial computers.
Ethernet is used to down-load programs to the quadra which compiles them into a
runtime module.  There is also an RF modem which is used to send telemetry to
another macintosh which is located remotely and allows a user to observe
internal inforamtion of the robot as well as provides a mechanism for traded
control. 


      2) The development environment used for both the workstation and
	 the on-board robot  e.g. GNU software, MPW (for the
	 Mac), X windows, MOTIF, VxWorks, CLIM, ...  

Code is developed in a lisp environment (Mac Lisp or on a uExplorer) using the
REX/GAPPS languages which reside inside of lisp.  The result is a circuit
definition which implements the developed algorithm.  The circuit is then sent
to a backend which generates a simulation of the circuit in C, Lisp, ...
We use the C backend.  The C code is then sent to the robot where it is
compiled and run.

      3) Languages used: C, LISP, Prolog, CLOS, ...

C, C++, Lisp

   Please send your responses (keep them short, please) to me
   (wlim@gdstech.grumman.com).  When I get enough responses I'll post a
   summary to comp.robotics.

   Thanks in advance.

Unfortunately, these are not short answers in our case.  We have at
least seven mobile robot systems and four manipulators and every one
has a different setup - everything from Suns running RCCL to 6811's
running ALFA.  Perhaps if you told me why you need to know I could focus
the answer appropriately.

Willie,
cc: benny, cet

Most robot configurations here in Field Robotics and Vision and Autonomous Systems
are mobile systems with some advanced manipulation work going on as well
(Khosla et al).

Nearly all workstations here are Sun SPARC's with a smattering of IRIS' for
simulation and graphics although the Sun's running XGL are pretty fast.
There are a couple of Macs too but are used only for some Mac applications
and not for robot control etc. We do have special purpose hardware as well with
a number of VME based systems, Maspar parallel processor, Titan graphics machine etc.

Development evironments are UNIX usually running X11R5 and/or Openwindows environments.
VXWorks is used for real-time development on most systems and CHIMERA (home brew RTOS)
is used also for some manipulator control.

There are extensively development systems for task control and communications such
as the Task Control Architecture (TCA) and large libraries of imaging software (GIL)

Language most used is C, not for any particular religious reasons but it is
most convienent and offers HLL power and LLL flexibility. LISP is also
used to a smaller extent.

Hope this helps.

Robot configuration: 

We are working with 20 small mobile robots.  The robots are
rectangular foot-long wheeled bases equipped with piezo-electric bump
sensors around the body, and a forklift for finding, carrying, and
stacking pucks.  The forklift has a suite of 6 infra-red sensors, two
for obstacle avoiding, four in the jaw for puck positioning, and two
for alignment and puck stacking.  The system also includes two radio
stations which allow the robots to triangulate their position, and
transmit and receive 8-bit messages at 1Hz.  This system allows us to
test a variety of collective and cooperative behaviors.

Workstations:
Macintosh IIsi, Macintosh II.

Development Environment:
Macitosh Allegro Common Lisp.

Languages: 

The robots are programmed in the Behavior Language, a high-level
parallel robot programming language.  The Behavior Language compiles
into the Subsumption Architecture, which further compiles into a
variety of target assemblers including HC6811 microprocessor assembler
which is what our robots use.
