      Hello all,

      My LEGO Mindstorms kit finally turned up a few weeks ago. A couple of
      evenings fiddling produced a working prototype for a remote-operated
      panohead.

      You can see it in action here: <http://ianjameswood.co.uk/ivrpa/
      nxt_mk0.mp4>

      I've started a progress blog about it on the IVRPA site: <http://
      beta.ivrpa.org/node/569>.

        Thanks! Part two is up with some closeup photos. This time, I thought a link to the blog as a whole (and not just one post) might be a good idea...

                  Hi Bernhard, Fischertechnik was never a big thing in Britain, so it never occurred to me to look at it. And secondhand LEGO is *very* easy to pick on on eBay.

                    Hi Bernhard,

                    Fischertechnik was never a big thing in Britain, so it never occurred
                    to me to look at it. And secondhand LEGO is *very* easy to pick on on

                              Not so much for 'regular' pano shooting as it's lighter, easier and
                              faster to use a normal panohead. It's more for hi-res pole panoramas
                              and experimental stuff like timelapse panos. Also I tend to do a lot
                              of shooting in low light situations where a simple 'camera on a pole'
                              won't do due to long shutter speeds.

                              Also, I plan to do a multi-GP pano for a challenge, and this will
                              help quite a bit...

                              Mindstorms is definitely easy to program, although it gets more
                              complex if you are trying to interact with the program via Bluetooth.

                                      I will do highres panoramas utilizing a Coolpix L2, a camera light
                                      enough for the Lego parts.

                                      The NXT programming kit is an excellent tool for learning the
                                      programming of robots but i already found some quirks which make
                                      programming more complicated than i expected to: The NXT brick supports
                                      more than one task at a time (3 to be exact) - but in the development
                                      GUI, you can either start the extra tasks in the beginning or the
                                      placement of the bricks becomes a horrible fiddling. Maybe i'll
                                      re-program the complete head software utilizing 2 tasks: a control task
                                      and a worker task...
                                      Also, i have a problem with motor movement. When i move back 360 degrees
                                      minus x degrees (e.g. 90 for a fisheye), the head is misplaced. The
                                      second sector is placed correctly. But this is no mechanical problem.
                                      I'm still investigating if i can find a workaround for this.
                                      Microsoft has released its "Robotic Studio" some weeks ago as a free
                                      download for non-commercial use. It also supports the NXT brick. So
                                      maybe i will do some experiments with this software...
                                      I can upload a video later, to show how it looks like...

                                        A general remark for all interested in building things on poles:

                                        Roger G Gilbertson, the founder of RobotStore.com suggested something that
                                        might help to minimize the unwanted swaying when stopping: to have an equal
                                        mass turn in the oposite direction. This would be accomplished with a
                                        "miter-gear" . With the miter gear setup, at least theoretically, it would
                                        be possible to shoot-turn-stop-shoot in rapid succession, reducing the wait
                                        for the rig to quiet down.

                                          Good idea, I might have a play with my G3, having already bought a second set of 'backup'
                                          motors and some spare gears. Bricklink.com seems to be a good place to get individual
                                          pieces.

                                          Hmm. I may have had a similar problem without realising. It's not there in my current
                                          program for 6+1 shots, but it's been re-written from scratch a couple of times while
                                          getting used to the app.

                                          Note that Robotic Studio is a tethered/Bluetooth solution, with all the logic operations
                                          taking place on the computer rather than the LEGO brick. So you'd always need a laptop
                                          with you.

                                            Thanks for telling. As soon as i'll experiment with a "big" head, this
                                            certainly will be necessary ;-)

                                            I don't understand either. I have now re-built the software and as far as i
                                            can see, the movement seems to be OK now.

                                            The Robotic Studio will be interesting if you plan to do tethered shooting.

                                            BTW: I've uploaded a video showing the robot in action:
                                            It's currently processing in YouTube
                                            http://www.youtube.com/watch?v=G2xksE2gZQE
                                            so you can also load a WMV here:
                                            http://dativ.at/temp/panobot_v1.wmv

                                            At the moment i can enter a "full stroke" for x and y movement (so you can
                                            define a full 360 degree panorama or only a sector that should be captured)
                                            and the number of shots in x and y direction. It doesn't calculate the
                                            correct number of images/row. This is still on my list. I will also add a
                                            special treatment if you only want to do an extra zenith shot.
                                            I'd also be interested to find out how to send a message via bluetooth from
                                            my mobile phone. It would make a nice feature if you can send a message to
                                            your robot to start shooting ;-)

                                              Hello Stephan,

                                              The motors are surprisingly strong (see more information on Philo's
                                              excellent website: http://www.philohome.com/nxtmotor/nxtmotor.htm ).
                                              The other parts and (also the plastic toothed gears) are not really
                                              suitable for a "real" camera. (I have choosen the L2 for my experiments
                                              because it is very lightweight (~200 grams), and still offers a decent
                                              image quality through its low (50) ISO ratings.)
                                              There are 3 motors in the NXT starter box: One is used for pan, one for
                                              tilt and one simulates your finger, pressing the shutter button. The
                                              "finger" is a extension Lego brick directly attached to the motor. The
                                              motor's power can be controlled exact enough to even simulate the 2-step
                                              shutter operations (e.g. "AF" and "shutter").

                                              Meanwhile i also bought a compatible mobile phone (there's a remote
                                              control software for mobiles on the Lego website) and i am exalted by
                                              the expanded possibilities this little gem offers: You can remote
                                              control pan, tilt and shutter function "out of the box" - and of course
                                              you can write your own software responding to user defined input. This,
                                              is what i'll do next... :-)

                                              Best regards
                                              Bernhard
