Contest Brief
Design a “Smart” Coarse-positioning Arm (SCA)
In this contest, you are asked to design a “Smart” Coarse-positioning Arm (SCA) that will be mounted to Astrobee and move a stowed end effector to a specified location and control the end effector. The SCA receives all power and high-level commands from the Astrobee free flyer, but implements the following functions autonomously: stowing and deploying from a payload volume, positioning its free end at a specified location near and Handrail, and orienting Astrobee by panning and tilting it.
How it works: Initially, the SCA will be packed in a stowed configuration. When powered and commanded by the Astrobee, the SCA must be capable of performing three operations autonomously:
1) deploy, which involves moving from a stowed configuration and placing an interface plate at a pre-determined location and then commanding the End Effector to attach,
2) orient, which involves the SCA moving the attached Astrobee side to side and up and down around the now-static interface plate, and
3) stow, which involves commanding the end effector to stow and then stowing itself and the attached end effector back in the stowage volume.

Challenge rules:
The prize will be awarded for the lowest mass, technically feasible solution, submitted by the contest deadline.
No working prototype 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) and the credibility of your mass estimate.
Only complete submission packages will be evaluated.
UPDATE: See "Figure 6 and Requirement 2 on panning and tilting.pdf" attached.

Employer Feedback
“Calix K. developed an innovative design for a “Smart” Coarse-positioning Arm (SCA) for a free flying robot designed for the International Space Station. This was a contest and this design was selected from 23 entries as the most feasible and least mass design. Calix K. provided an impressive design submission and has been very responsive in providing everything that is needed. This was the 2nd contest where Calix K. has developed the winning robotic solution.”
