[13:48:50] PernosDetunaCTJIII: Greetings
NASA crew
[13:50:35] PernosDetunaCTJIII: so...
No informal chat once the class starts?
[13:53:02] AlexThompson: Does anyone
know how we are being graded on or quizes?
[13:53:19] AlexThompson: or the report
fo that matter?
[13:54:25] wildkid: Hello all!
[14:01:08] NASAModerator: We have
begun. You should be receiving video
[14:01:11] PernosDetunaCTJIII: Alrighty
hush hush time
[14:02:04] AlexThompson: Im on theast
coast and Im out of school...
[14:05:11] PernosDetunaCTJIII: I
have video
[14:05:26] AlexThompson: I have video...
try windows media player
[14:05:32] NASAModerator: Hi Pernos,
are you using Real Player?
[14:05:53] EricHoerle: ok i got the
video now
[14:06:07] matthewjohnston: what
slide are we on?
[14:06:22] EricHoerle: im using mediaplayer
[14:07:42] wildkid: ok i got video
[14:07:50] wildkid: windows media
is good
[14:07:58] NASAModerator: The video
is in process.
[14:10:18] DanielPoynter: http://robotics.nasa.gov/courses/fall2002/event/chat/chatmain.html
for technicul difficulties...
[14:11:03] LiYangLiu: Excuse me,
the video won't open up on my Windows Media Player
[14:11:18] PernosDetunaCTJIII: ::raises
hand:: did I miss something or did he not talk about how this thing'll move
in a place with no atmosphere?
[14:11:52] NASAModerator: @ http://robotics.nasa.gov/courses/fall2002/event/sept26/index.html
you can select the slide numbers
[14:14:07] AlexThompson: good point
pernos... maybe it uses rocket boosters
[14:14:40] PernosDetunaCTJIII: that's
what he said
[14:15:04] AlexanderReben3: every
action has a equal and opposite reaction
[14:16:02] AlexThompson: I wonder
how they store the fuel...
[14:16:06] PernosDetunaCTJIII: I
was just listening to him talk
[14:16:30] RobertBall: will this
video be availible later for download?
Yes
[14:16:42] RobertBall: I think that
It would be intetresting to see it
[14:17:05] AlexanderReben3: all it
has to be is some compressed gas
[14:18:38] NASAModerator: This webcast
will be archived this evening.
[14:19:34] wildkid: Is the AERCam
Sprint still up in space?
[14:19:47] NASAModerator: Please
place your questions here so we may relay them to Dr. Fredrickson
[14:20:53] AlexanderReben3: what
does it use for angular rate measurement? a gyroscope?
[14:21:27] AlexanderReben3: how far
can the control signal reach?
[14:22:25] JacquelineMehlberg: Why
is it a sphere, and how much does it weigh?
[14:22:29] AlexanderReben3: does
it have any sensors besides video (distance etc...)
[14:22:29] DanPoynter: oops, sorry
i didnt know i typed that in this chatroom : \
[14:22:30] matthewjohnston: what
gas does it use to propel it?
[14:22:31] PernosDetunaCTJIII: Question
1: How heavy is the AERCam?
[14:23:00] AlexThompson: We have
to numbe our questions...
[14:23:13] PernosDetunaCTJIII: Question
2: How much did it cost to make?
[14:23:23] AlexanderReben3: what
do its propulsion systems consist of?
[14:23:46] DanPoynter: What are your
thoughts on putting many of these things up in orbit, outside of the space station,
maybe even keeping the SS as their homebase, and they would zoom around orbit
doing msc. tasks, like checking on satelittes?
[14:24:00] AlexThompson: Because
a sphre takes up the least amount of room and still takes up a minimum amount
os sace
[14:24:15] JacquelineMehlberg: What
were any prototypes? What are the next steps in AERCam's development?
[14:24:35] MB: What Slide are we
on Please?
[14:24:44] AlexThompson: okay im
confused... do we ask our questions NOW or durig the actual chat
[14:24:56] matthewjohnston: whare
was AERcam made?
[14:25:50] BradGates: Question 1:
How many AERcam's do you plan to have aboard the ISS?
[14:27:04] BradGates: Question 2:
How fast can AERcam move?
[14:27:21] EricHoerle: ::Question::
How many AERCams are there right nwo?
[14:28:45] Ross_Bowman: What kind
of computer system does the AerCam use?
[14:29:58] AlexThompson: oh sorry
jaqueline... what I meant to say was that a sphere gives you the most storage
room in relation to to taking up a smaller amounts of space as compared to something
like a square
[14:30:07] EricHoerle: ::Question
II:: Could the AERCam be controlled from Earth or does a spacecraft have to
go up every time instead of just leaving it?
[14:31:11] JacquelineMehlberg: Thanks
Alex.
[14:31:48] BrianWoodworth: Question
1: How far can it travel without having to refuel?
[14:31:54] MB: What is the exacted
jod the AERCam does?
[14:32:44] RHS: Question 1: How long
can AERCam mini stay out in space (before battery goes dead, fuel low) ( Nik
Krumm)
[14:34:49] RHS: When will the AERCam
be launched in Space (projected date) (Lauren Delgado)
[14:36:01] JennyGimian2: What is
the casing made of?
[14:36:33] RobertBall: Wouldent the
Xenon propulsion be really slow?
[14:37:11] AlexThompsn: why would
it be slow...
[14:38:01] EricHoerle: yah why
[14:38:20] AlexanderReben3: What
frequency does this operate at
[14:38:39] AlexanderReben3: 2.4ghz
i would guess
[14:39:17] AlexThompsn: This we class
thing is pretty cool but its a lot easier to zone out than in a real class room:)
[14:39:47] RHS: What is the GSE port,
what is it use (Riley Gorder)
[14:42:07] RobertBallIECRASH: AlexThompsn
, I was thinking of ION propulsion. sorry :)
[14:47:10] BrianWoodworth: Question
2: When will the AERCam be ready for a mission?
[14:47:28] RHS: why don't you test
it in water? Bouyancy problems? (Chris Zweigle)\
[14:47:59] BrianWoodworth: What is
the case made of?
[14:48:05] AlexanderReben3: Will
astronaughts have a hud and their own controls for such a device?
[14:48:16] AlexanderReben3: *good
spelling
[14:48:49] DanPoynteragain: Yay!
[14:48:52] DanPoynteragain: :D
[14:49:08] AlexThompson1: What kind
of computer does the aercam use
[14:49:41] AlexThompson1: I dont
believe this...
[14:49:49] johnputrino: Why is the
free flier round? Doesn't it not matter if it's working in space?
[14:50:00] PernosDetunaCTJIII: Question
1: How heavy is the AERCam? Question 2: How much did it cost to make?
[14:50:04] EricHoerle: How efficiant
are the AERCams?
[14:50:27] DanPoynteragain: Question
1: what are your thoughts on using these robots outside of a space craft more?
suppose they were to fly around in orbit, and check on satellites...
[14:50:58] RHS: Question #2: What
kind of emergency recovery features are there? What if it gets lost? (Nik Krumm)
[14:51:22] JennyGimian2: What would
the final version of the Aercam look like?
[14:51:27] AlexThompson1: Does the
aercam have any AI capablities....
[14:51:30] DanPoynteragain: Question
2: What are your thoughts generally on the future of robots like the mini AER
cam?
[14:51:48] RHS: Question #2: Why
did you choose to make it a sphere? Isn't it easier and more space efficient
in a cube/rectangular shape? (Chris Zweigle)
[14:52:54] DanPoynteragain: Question
3: What is NASA's stance on using evolutionary software to power robots like
mini AER cam ?
[14:52:58] johnputrino: How much
did it cost to build the AERCam?
[14:53:03] AlexThompson1: what language
did you use to program it
[14:53:14] RobertBallIECRASH: //////
Will there have to be any additional equipment attached to the Space station
before the AERCam will be deployed? ///////
[14:53:33] PernosDetunaCTJIII: Question
1: How heavy is the AERCam? Question 2: How much did it cost to make?
[14:54:14] matthewjohnston: whare
was AERcam made?
[14:54:23] wildkid: Does the AERCam
take close up pictures of the earth?
[14:54:56] AlexThompson1: have you
thought about using robots similar to the aercam to tranport equipment in space
[14:55:07] DanPoynteragain: Thank
you for answering that question : )
[14:56:23] matthewjohnston: what
gas does it use to propel it?
[14:56:42] AlexanderReben3: nitrogen
[14:56:54] RHS: what competition
does the AERcam face? (Lauren Delgado)
[14:57:40] AlexThompson1: it uses
xenon.... he said that earlier
[14:57:53] AlexanderReben3: why power
pc? i noticed it was on some of the other robots?
[14:57:56] matthewjohnston: k
[14:58:24] JacquelineMehlberg: How
large is the team that is working on AERCam?
[14:59:56] JennyGimian2: When was
construction begun on the Aercam?
[15:01:20] RobertBallIECRASH: it
uses both propulsion gases... depending on its location
[15:01:29] AlexThompson1: SHE ASKED
MY QUESTION!!!
[15:01:48] JacquelineMehlberg: What
are some other functions you can imagine for free fliers?
[15:02:17] RobertBallIECRASH: will
there be a link on AERCam's website to control the AERCam from the internet?
[15:03:52] AlexThompson1: have you
given any thought to shooting the aer cam into space and then just using a chain
of satellites to get its pictures
[15:05:01] AlexanderReben3: could
astronaughts use HUD's and their own controls for help out in space?
[15:05:34] DrMC: The first AERCam
certainly took a tremendous amount of development time. How much do you estimate
it would cost now to make duplicates? Dr. Cummings
[15:06:03] RHS: whats new features
will be available in next generation of AERCam's?
[15:06:18] RHS: oh I am Riley Gorder
[15:06:48] AlexThompson1: #:15....
where are you buddy Montana?
[15:07:54] johnputrino: What requirements
are there for being able to fly the free flier?
[15:08:00] AlexThompson1: can the
AerCam eng signals to multiple receivers
[15:08:02] Seth: RedOctober wants
to know "when if ever will the aerocam be ready for home use or just for fun"?
[15:10:01] DrMC: Do you think there
will be opportunities for students to control an AERCam for an ISS inspection?
[15:10:02] AlexThompson1: why dont
you putmore cameras on the AerCam... then you wouldnt have to rotate it as much
and thus save fuel
[15:10:20] DanPoynteragain: Question
4: How many people did it take to get to where you are with this robot, also,
approximate man hours
[15:11:17] AlexThompson1: I got two
questions.... Im on a roll!!!
[15:11:31] Seth: How much does the
AERcam use per hour - Leornian
[15:11:37] Ross_Bowman: Question:
What kind of computer system does AerCam use?
[15:13:21] LiYang: Question1: Could
the AERCam be used to investigate other planets?
[15:14:45] JacquelineMehlberg: What
would it take to make a free-flier that could operate in the atmosphere? Could
this have reconnaisance applications?
[15:15:35] AlexThompson1: Can the
AerCam have network capabilities i.e. could you use 5 and putthem all around
the shuttle and then if one saw a problm could it call the others to it for
muliple angles
[15:16:56] AlexThompson1: NOOOOOOO!!!!!!!!!!!
[15:17:07] DanPoynteragain: thank
you dr
[15:17:11] BrianWoodworth: Thank

[15:18:37] AlexThompson1: It should
be in screen 2...
[15:19:04] AlexThompson1: and it
is currently unavailable
[15:19:06] Mathews: wher is the quiz
[15:19:19] DrMC: Have a great weekend
everyone. NO QUIZ TODAY. This should give everyone a chance to get caught up
on the archives, if needed...
[15:19:45] AlexThompson1: Exscuse
me DrMC.... what did you earn your doctorate in?
[15:20:30] AlexThompson1: No, actually
Ill probably be getting caught up in Physics:)
[15:20:51] AlexThompson1: ... and
AP European but thanks anyway
[15:20:56] Ross_Bowman: Thanks
[15:21:06] DanPoynteragain: Thank
you Dr. Cummings
[15:22:10] JacquelineMehlberg: thank
you.
[15:22:17] DrMC: My doctorate is
actually in Biological Oceanography. While that is actually a very interdiscplinary
area, my interest in robotics began a little later - while I was teaching.
[15:22:20] Ross_Bowman: later all,
have good weekend to u all
[15:22:48] AlexanderReben3: bye all!!
[15:24:15] AlexThompson1: Cool...
so I can do biology AND robotics
[15:24:28] AlexThompson1: ...sweet
[15:26:06] AlexThompson1: IVe been
worry over that for the last week..... thanks for the fun time I learned a lot
