  Arduino Code.
  
  

  I cant seem to find the Arduino code at the moment.  its been a few years.
  i will post here if i do come across it
  but there is nothing special here and it will depend on the hardware used.
  
  Left + Right  buttons   pans the robot a few steps left or right to set the start frame.
  as well as choosing the direction of the panorama sequence 
  
  Center button is the "start" button  and if in the middle of a sequence "pause"
  and LED's indicate condition

  when started. the robot runs a set sequence. 
  in this case  3 elevations (servo motor)  with adequate picture overlap
  and stepper motor for azimuth also with adequate picture overlap

  the robot positions the camera, pulses the camera USB 5V when its arrived to
  request an exposure.  then looks for the camera to respond with a "blink" 

  move to next position.  repeat.
  finishing the sequence with a Zenith (straight up)  and Nadir (straight down) frame
  and at the end of the sequence it "rewinds"  to start  position (cable management)
  
  
  

• Lua script description

  Rune Kyndal • 06/12/2020 at 14:26 • 0 comments

  Lua Script

  when the Lua script is started on the camera,  
  it activates the cameras "half press"  to focus and AF lock the camera.   
  this half press is "held" throughout the whole sequence 
  to keep the focus from changing between exposures. 

  the script then waits for the Arduino to pulse the USB "HIGH",
  which is received as a trigger event from CHDK.

  the script initiates the exposure by having the camera go  "full press" and back to "half press"   
  half press is not released until the end the exposure sequence.

  the camera must be set to fixed exposure(s), to avoid the picture changing,
  with varying light conditions as it pans around.
  
  

  blinking the LED is done by poking directly to the Cameras hardware registers, 
  specific to the camera type.  for the 110HS  its 0xC0220164 and 0xC022C028
  
  I forget the details now. but I believe I based my Lua script on the  HDR Fast Shooter script
  adding a few things, menus,  detection of finished exposure, and of-course the LED blink function.

• Pano-bot Videos

  A video i did for a Nikon Competition.
  
  its an early version.  early software. buggy as is apparent.   
  I did not have the camera control implemented yet.  (only the Arduino to Camera trigger) 
  but it shows the Robot and its sub-parts if nothing else.

  Nikon Competition Video
  
  another older video..  description says "faster firmware" 
  well it got much faster since then
  
  "not so "faster" Robot firmware video"
