Contest Brief

Design a Positioning Software Architecture (PSA)

In this challenge, you are asked to design the Positioning Software Architecture (PSA) that will control a Robotic Arm (RA) that has been separately designed to attach the Astrobee Robotic Free Flyer to a Handrail within the International Space Station. This challenge is focused on software and software architectures, and no executable code is required.

How it works: The PSA will receive a positioning command from Astrobee and implement it through the RA’s control electronics that will drive the RA’s motion. The PSA should include the high-level motion-planning algorithms necessary for the RA to
(1) move from Astrobee’s payload bay and move to a commanded location, and
(2) stow back into the payload bay, without making contact with any parts of Astrobee or the ISS.

Challenge rules:
The prize will be awarded for the lowest cyclomatic complexity, technically feasible solution, submitted by the contest deadline.
No working code is required for submission, but the design must be sufficiently detailed to allow experts to assess the feasibility of your design (i.e., comply with all requirements). Only complete submission packages will be evaluated.

This contest is now closed. Thank you all for your submissions and all of the hard work. If you have not provided an exit survey code yet with your submission, you may still provide that code via the chat. We just launched 4 more challenges, so hopefully you can get some rest and consider engaging on these new challenges.

Hi regarding the flowcharts does it have to be one comprehensive diagram or can several be made?

  We would prefer one comprehensive diagram. We should be able to see how your singular system interprets various inputs to result in various outputs.

We will be extending the deadline on this contest once Freelancer updates the main contest page since currently, there is no link to this page.

Hello, I think this challenge is referred to SPAM project, so I'm quite confused about the fixed robotic arm design in your problem description. I know the architecture of a software will allow you to modify it according to your needs, but probably your SPAM choice will not be much different from the fixed one.

  We provide a basic robotic arm conceptual design such that all Freelancers can compete on equal ground.

  The robotic arm design here is a reference design to allow us to get software solutions for how to best do positioning. It can seem similar to other challenges (like SPAM) because all the challenges are parts of astrobee perching and operating on a handrail.
  We are looking for the best software solution that uses the reference design described in the PSA challenge. Different approaches are definitely encouraged as long as they meet the requirements in the problem documentation.
