David Whiteis has loaned the **CRS/Fisher F3 Robotic arm** to Dr. Nuno
|
|||
|
Martin's group at the University of Maryland.
|
|||
|
|
|||
|
HacDC members interested in working with the robot should get in touch
|
|||
|
with David.

**We are currently gathering ideas about what we might do with the
|
|||
|
robot. Here is part of what we have come up with so far, shown in groups
|
|||
|
and including sample videos where possible.**
|
|||
|
|
|||
|
We may use this wiki page to document what we have learned about the
|
|||
|
robot, what projects are proposed, planned or implemented, and more
|
|||
|
videos of the machine in action.

## Moving and stacking stuff:
|
|||
|
|
|||
|
Grabbing dominoes from a stack, setting them up to tumble over in a row:

|
|||
|
|
|||
|
## Videoing stuff:
|
|||
|
|
|||
|
Holding a video camera in the gripper, and filming while in motion:
|
|||
|
<http://www.youtube.com/watch?v=2GDsFChduiI> That second video gives a
|
|||
|
limited overview of the robot's ability as an advanced 3D video camera
|
|||
|
dolly. We know a lot more about what is possible now. You could make
|
|||
|
some amazing videos with that setup. Here are some of the lessons
|
|||
|
learned:
|
|||
|
|
|||
|
`- Videoing miniatures such as model train layouts is fun and gives great results.`
|
|||
|
`- Get in close, and don't pan too much. `
|
|||
|
`- Keep a single object as the center of focus, and change the camera location while keeping that focus.`
|
|||
|
`- Track moving objects making complex movements, like a model train following a track.`
|
|||
|
|
|||
|
The O scale train in the above video was good, but tracking a smaller
|
|||
|
train (HO or N scale) would be much better, since then the robot could
|
|||
|
track the train through multiple left and right turns, much like a
|
|||
|
real-world helicopter filming a train for a Hollywood movie.
|
|||
|
|
|||
|
David plans to reach out to model train enthusiasts to see if there is
|
|||
|
interest in collaborating on a movie that really shows off the
|
|||
|
technology.
|
|||
|
|
|||
|
David sent an email on 3-8-13 to 'marylandfilmmakersclub@gmail.com' to
|
|||
|
see if the film school students at
|
|||
|
<http://www.marylandfilmmakersclub.com/home.html> are interested in
|
|||
|
collaborating on a project.
|
|||
|
|
|||
|
You could do great stop-motion animation with the setup. Your camera
|
|||
|
could move slightly every time your parts/clay are moved, making for a
|
|||
|
much more dynamic and flowing movie than when the camera stays in a
|
|||
|
static position.
|
|||
|
|
|||
|
If you programmed the arm to move the camera through the air in a big,
|
|||
|
elaborate flowing path, and then had someone who was a hotshot at flying
|
|||
|
miniature RC helicopters fly a pattern that kept it in front of the
|
|||
|
lens, that would make an amazing video.
|
|||
|
|
|||
|
## 3D printing, or subtractive CNC machining:
|
|||
|
|
|||
|
We have talked about mounting a plastic extruder, Dremel router, or
|
|||
|
cutting laser on the tool post, but we have not done any of this yet.
|
|||
|
Will it be you that drives this project?

## More on Maker Tech Tuesdays:
|
|||
|
|
|||
|
For several months the F3 robot was at Chas Colburn's place, before it
|
|||
|
was loaned to the University of Maryland.
|
|||
|
|
|||
|
Maker Tech Tuesdays is a hackerspace provided by Chas Colburn at his
|
|||
|
place of business, 3DMetalParts, just south of the University of
|
|||
|
Maryland. The space is free to visit and is open every Tuesday.
