The lab has supported through the years several sponsored projects and was largely funded by NASA grants ($1,500,000). The lab will be used in an upcoming NSF grant (11/2 due date) that is being developed this semester on active learning in engineering education. The mechanical work in the grant will be made using the specialized machining capabilities in the lab.

The lab supports an active doctoral student (Trigun Maroo) who is developing a drone project for precision agriculture. This project should lead to funding opportunities in Arkansas. The student needs fabrication equipment, space to test the drones, measuring equipment to characterize the devices, and secure storage space for materials and equipment.

The lab is used to support both Capstone and Mechanical Design classes. In the past, students who need specialized instruction or access when UA Little Rock shop personnel are not available have been accommodated by Dr. Wright in ETAS 530. Having the fabrication space adjacent to the Capstone room (ETAS 529) allows students to assemble their projects and use the tools in ETAS 530, rather than trekking down to the UA Little Rock shop.

The vibration equipment will be used to support the new vibrations course which will be required with the beginning of the Mechanical Systems Engineering program beginning in Spring 2017.

The plastics fabrication equipment will be used to support SYEN 2118. Fabrication Lab II, which will be required with the beginning of the Mechanical Systems Engineering program beginning in Spring 2017.

Dr. Wright uses this facility to support his independent research projects. For instance, the CASSY robot platforms have been designed and built in conjunction with the ETAS 530. Since the machines can be configured and left set up, Dr. Wright can perform work in ETAS 530 that he cannot perform in the UA Little Rock shop, which has to be reconfigured for student projects on an hourly basis.

The servers, theduchy.ualr.edu, calliope.ualr.edu, and robotics.ualr.edu, are configured to use the ports in ETAS 530. Although this is not a critical feature of the lab, if the servers were to be moved, ITS would have to reconfigure 3 ports elsewhere on campus to the 144.168.99.xxx subdomain. Right now, 226, 227, and 228 are allocated to these servers and locked to the ports in ETAS 530. This would create disruption in several critical features that support campus and national obligations.

The server, calliope.ualr.edu is currently serving the course materials for SYEN 2233. This course has large video requirements that need more drive space than ITS provides.

The server, calliope.ualr.edu is currently serving the library of faculty senate minutes until a digital archive can be configured. This has been done temporarily to give the provost’s office and collections and archives time to develop the plan for taking this task over.

The server, theduchy.ualr.edu, has been in continuous operation since 1996. It has served as a mirror for NASA’s first Mars rover video archive in the 2000’s. Dr. Wright’s course materials have been linked from many different sites over the years. A google search reveals about 600 external links to theduchy.ualr.edu. The server, theduchy.ualr.edu also links files for a few publications that Dr. Wright has received and is the primary server maintaining the data archives from past NASA and NSF grants (see data management plan).

The server, robotics.ualr.edu is not as critical; however, the domain can be used (and has been used in the past) as an entry point for external viewers to see all of UA Little Rock’s robotics work. The server has been disrupted in recent months by UA Little Rock’s power outages, which have killed two motherboards. The replacement motherboard was finally obtained last week after about four requests for purchase across two chairs, and the server should resume its function presently.

Robotic Lab (Capstone Room)

Location: ETAS 529

Summary of the equipment and the estimated $ value:

Materials and Supplies purchased through Capstone program: $5,000

This room is used as both a capstone project assembly room and space for undergraduate and graduate students to have temporary access. The key feature of the room is its size and the programmable magnetic lock on the door. Students can be given temporary access without the need to cut keys and revoke them when the space is no longer needed.

The pace is adjacent to Dr. Wright’s research lab (ETAS 530) and gives students easy access (usually through a graduate student) to tools and machines that facilitate assembly.

The room currently supports Capstone I&II, Elements of Mechanical Design, two undergraduate students independent studies (Jean Pamphile, Priscila Almeida), Trigun Maroo (doctoral student), and the Dancing Robot project (in conjunction with Theater and Dance).

If this space is reallocated, some other project space will have to be allocated for the capstone students’ projects (in particular). Such space should have easy access to the UA Little Rock machine shop so that assembly can be facilitated and should have the ability to provide revokable access to students so that they don’t need someone to open the doors for them.

Brief description:

Power Systems Lab provides equipment and service for fundamental experiments of power systems, including three-phase systems, power transformers, electric machines, synchronous generators and operation. It also supports the experiments in power electronics, electronics design, and microprocessors and systems.

Recent development is the remote-accessible experiments of electric power systems by developing special interface between physical experimental system and computer, and using LabView workstation so that the experiments can be completed by computer and network. Remote-accessible experiments have been used for microprocessors & systems lab during last few years. Two Capstone projects have been completed to develop remote-accessible experimental systems for power transformers and synchronous generators. A NSF proposal “Cyber-Physical Experimental Systems for Electric Power Engineering Education” will be submitted on Nov. 2, 2016.

Power Systems Lab supports the two undergraduate Lab courses SYEN3134 “Microprocessors &Systems Lab”, SYEN3158 “Power Systems Lab”. Each semester around 10 undergraduate students use the lab to complete assigned lab projects. It also supports graduate course, “Introduction to Power Electronics”. The graduate students use the lab to complete the lab projects in the course.

The lab also supports undergraduate Capstone projects, master graduate thesis, and PhD graduate dissertation research projects. Currently there are two PhD students use the lab intensively for their research projects.

The lab provides the support for High School Research Program. During last three years, there were three high school students joined the lab to complete their research projects in summer.

ETAS208 shared with Dr. Iqbal and Dr. Kim for graduate students. It is also used for the inventory for best robotic hub.
