DARPA DMACE Challenge

(Digital Manufacturing Analysis, Correlation and Estimation)


Final Challenge closed at 1630 EST, 06DEC10

This is it!

For a valid entry, you must enter your estimation for both a sphere and a cube configuration, and submit your model summary (PDF preferred, 20Mb maximum).

Once you submit your entry, it will be given a time stamp. Results will NOT be viewable on the Leader Board page. You can tweak your model and update your entries here until the Final Challenge session closes out, but each re-submission will have a later time stamp. In the case of a tie, the participant with the earlier time stamp will be the winner.

To submit your entry for the DMACE Final Challenge, answer the following question:

What is your estimation (in newtons) of the maximum compressive load of a sphere that is digitally manufactured using the following settings?:

- Current = 2.5mA
- Velocity = 110 mm/sec
- Crush Angle = 60 degrees

What is your estimation (in newtons) of the maximum compressive load of a spiral-cubic structure built with tip size 16 (0.254mm) at raster angle as depicted (see 'SpiralWebWindowCube_V2_dwg.pdf') and a build angle along the Z axis that has these dimensions?:

- 100 mm x 100 mm x 100 mm (outside dimension)
- Wall thickness 5mm
- The top and bottom sides are open while the remaining four sides have an 'X'-shaped structure. (You can reference three different formats of CAD files, a rotatable PDF, an axis-orientation PDF and a PDF drawing available on the 'Final Challenge Cube Data' page)
- The compressive load will be applied along the Z-axis; that is, in line with the axis of the spiral inset


Entry Round:
Sphere Prediction:  Newtons 
Cube Prediction:  Newtons 

By submitting an entry, a participant authorizes his or her name to be released to the media if the participant wins the prize. DARPA does not require that participants relinquish or otherwise grant license rights to intellectual property developed or delivered under the Challenge.
DARPA does not plan to retain entries after the Challenge is completed, but will compute aggregate statistics. DARPA may contact participants to discuss the means and methods used in solving the challenge.

 


Practice #3 closed at 1300 EST, 02DEC10

Here's the last 'practice' opportunity to experience how we'll ask for your final estimations of the cube and sphere properties to win the $50,000. This is for practice only; it will have NO bearing on the final winner of the DMACE Challenge or the award.

For this third practice, we're again asking a question related to the initial conditions of a test set of spheres AND the second test set of cubes. We’re also having you submit a file (PDF preferred, no more than 20 Mb file size) so you can see how submitting your model summary will work in the Final Challenge.

Once you submit your entry, it will be given a time stamp. Unlike previous practice questions, results will NOT be viewable on the Leader Board #3 page. You can tweak your model and update your entry here until the Practice #3 session closes out, but each re-submission will have a later time stamp. In the case of a tie, the earliest time stamp will be the winner. The Leader Board #3 page will be viewable at 1330 EST, 02DEC10.

The Final Challenge questions, estimation entry and file upload will be similar to the format on this page.

To submit your entry for Practice #3, answer the following question:

What is your estimation (in newtons) of the maximum compressive load of a sphere that is digitally manufactured using the following settings?:
- Current = 2.1mA
- Velocity = 100 mm/sec
- Crush Angle = 90 degrees

What is your estimation (in newtons) of the maximum compressive load of a lattice-cubic structure built with tip size 16 (0.254mm) at raster angle 90 degrees and build angle 90 degrees that has these dimensions?:
- 100 mm x 100 mm x 100 mm (outside dimension)
- Wall thickness 5mm
- The top side is open while all five sides (including the bottom) are lattice walls. (You can see a JPG image of the structure, three different formats of CAD files and a rotatable PDF available on the 'Week 4 Data (Cube)' page)
- The width of each lattice cutout is 10 mm x 10 mm
- Raster direction was along the X-direction
- The compressive load was applied along the Z-direction; that is, crushed from the top down.
Entry Round: Practice #3
Sphere Estimation: XXXXX.XX newtons
Cube Estimation: XXXXX.XX newtons


Entry Round:
Sphere Prediction:  Newtons 
Cube Prediction:  Newtons

Practice #2 closed at 1630 EST, 29NOV10

Here's the second opportunity to experience how we'll ask for your final estimations of the cube and sphere properties to win the $50,000. This is for practice only; it will have NO bearing on the final winner of the DMACE Challenge or the award.

For this second practice, we're now asking a question related to the initial conditions of a test set of spheres AND the first test set of cubes.

Once you submit your entry, it will be given a time stamp and your results will be placed on the Leader Board #2 page. You can tweak your model and update your entry here until the Practice #2 session closes out, but each re-submission will have a later time stamp. In the case of a tie, the earliest time stamp will be the winner.

This is exactly how the Final Submission will work, with two exceptions:

1) To be valid, your final entry must include your models and a brief description of the techniques used in the development of your models (PDF is preferred)
2) We won't be giving rankings for estimations until after the final submission period is closed (1630 EST 06DEC10), since we won't have tested the final configuration until after that date anyway (one of the benefits of digital manufacturing!)

To submit your entry for Practice #2, answer the following question:

What is your estimation (in newtons) of the maximum compressive load of a sphere that is digitally manufactured using the following settings?:
- Current = 2.1mA
- Velocity = 200 mm/sec
- Crush Angle = 90 degrees

What is your estimation (in newtons) of the maximum compressive load of a cubic structure built with tip size 16 (0.254mm) at raster angle 90 degrees and build angle 90 degrees that has these dimensions?:
- 100 mm x 100 mm x 100 mm (outside dimension)
- Wall thickness 5mm
- Top side is open while all five sides (including the bottom) are solid walls. (You can see a JPG image of the structure in the 'Gallery' named: "T-16 Solid Cubic test structure.JPG")
- The crushing angle is in the –Z direction; that is, crushed from the top down.

Entry Round: Practice #2
Sphere Estimation: XXXXX.XX newtons
Cube Estimation: XXXXX.XX newtons


Entry Round:
Sphere Prediction: Newtons 
Cube Prediction: Newtons

Practice #1 closed at 1630 EST, 23NOV10

We're giving you a chance to experience how we'll ask for your final estimations of the cube and sphere properties to win the $50,000. This is for practice only; it will have NO bearing on the final winner of the DMACE Challenge or the award.

To keep this simple for this first practice, we'll just be asking a question related to the initial conditions of a test set of spheres.

Once you submit your entry, it will be given a time stamp and your results will be placed on the Leader Board page. You can tweak your model and update your entry here until the Practice #1 session closes out, but each re-submission will have a later time stamp. In the case of a tie, the earliest time stamp will be the winner.

This is exactly how the Final Submission will work, with three exceptions: 1) You'll be entering an estimation for both a cube AND a sphere final configuration 2) To be valid, your final entry must include your models and a brief description of the techniques used in the development of your models (PDF is preferred) 3) We won't be giving rankings until after the final submission period is closed (1630 EST 06DEC10), since we won't have tested the final configuration until after that date anyway (one of the benefits of digital manufacturing!)


To submit your entry for Practice #1, answer the following question:

What is your estimation (in newtons) of the maximum compressive load of a sphere that is digitally manufactured using the following settings?:
- Current = 1.3mA
- Velocity = 100 mm/sec
- Crush Angle = 90 degrees
