Activity 9.5 Case Analysis Effectivness



I think that the case analysis was very effective in facilitating deeper research and understanding of unmanned systems by the students as well as getting a better idea about the challenges ahead.  While the class was very thorough and covered a wide range of topics nothing helps the learning process and the expansion of knowledge as much as research.  Searching and sifting through the vast amount of information available to us today opens you up to finding information and stories that you never would have thought to look for.  In this aspect I think the case analysis excelled in its purpose.

This tool also helped to develop more analytical thinking about the problems faced by unmanned systems and made us more aware of opposing or just different viewpoints on these issues as well as UAS themselves.  This type of decision making is can be very relevant to my line of work as a UAS flight instructor.  Because this is such a new and growing industry with many challenges facing it now and in the future good decision making will be crucial. A case analysis provides the ability to have well thought out and logical reasoning about and issue and puts it in a package to present to others for review and consideration.  I don’t think there are many areas that this type of paper and problem solving would not be applicable. A recent example that would this type of research would have been applicable would be when I was working on finding a way to improve the process for updating our lesson plans.  We used Six Sigma practices for this at the time but this process of researching and presenting a case analysis would have been just as effective.  Another example would be using a case analysis to show some safety of flight issues that we have because of inexperienced personnel being put in decision making positions.  A case analysis could be used to show them what the problem is and how to fix it in a logical and subjective manner.

I don’t really see any way to improve the process for an online class. Of course in actual classroom environment more collaboration between students and more frequent feedback would be very helpful for this process.  For this class I think it was done as well as it possibly could be.

This will be a request for proposal of a quadcopter system used for disaster search and rescue applications.  This will be for a small man portable system appropriate for searching in remote areas with minimal support equipment.  The goal will be to select a COTS (Commercial Off the Shelf) system as well as a COTS payload that can be easily integrated into the quadcopter platform.  By using a COTS system this reduce development and testing time (less than 6 months) providing a proven platform for this application.

Base Requirements

·       Transportability

o   Entire System (all components) will be transportable (in ruggedized case) and weigh less than 50 lbs (one person lift)

o   Entire system (all components) will be transportable in padded backpack for field use

o   Control Station shall be tablet (ruggedized) for field use

·       Air Vehicle

o   Shall be capable of flight up to 500 feet altitude above ground level (AGL)

o   Shall be capable of sustained flight for a minimum of 45 minutes

o   Shall be capable of operational radius of at least 1 kilometer mile

o   Shall be autonomously controlled via ruggedized tablet control station

o   Shall be deployable (from either case or backpack) and over mission area in less than 15 minutes.

o   Shall provide real time telemetry information to operator via ruggedized tablet including altitude, magnetic heading, latitude/longitude or MGRS (Military Grid Reference System) position, and orientation (roll, pitch, and yaw)

o   Shall provide near real time payload video to ruggedized tablet control station

o   Shall provide capability to hover over target of interest

o   Shall provide power to payload, telemetry sensors,  and data-link

·       Payload

o   Shall be capable of color daytime video (EO) operation up to 500 feet AGL

o   Shall be capable of infrared (IR) video operation up to 500 feet AGL

o   Shall provide target location coordinates (MGRS, Lat/Long, etc.)

o   Shall be at least 2 axis gimbal stabilized

o   Shall be interoperable  with C2 and data-link

o   Shall use power provided by air vehicle element


For this system I would look at getting a COTS (Commercial Off the Shelf) system that would require little actual development other than slight modifications and validation that the system is capable of meeting the mission requirements.  For this reason I would use an unstructured of ad hoc development process.  I would use the following testing strategies:

1)     Concept Design

2)     Concept Research (COTS)

3)     Subsystem Testing

4)      Integration Testing

5)     Test Site Selection

6)     Flight Test

7)     Certification

8)     Support

Because this will be a COTS system with only minimal payload selection and integrations this process should take no longer than 4-6 months.

 

I have decided on COTS quadcopter system because they are usually modular in nature with excellent payload capability.  This type of system is also very well suited to this application because it can hover and provide a stable platform with a 360 degree view for the payload.  This capability will provide rapid search of difficult or inaccessible terrain.

 

By using a COTS system this will ensure the system is available for use as quickly as possible and will ideally already be proven with previous operational use.  This will also keep costs down and making this system available to search and rescue units of all sizes and budgets.  This will also eliminate production problems related to setting up a new facility and the associated development and production delays.
