A Finite Element Study: Kinematic Mounts for Large Mirrors
close

‘Imaka is a ground-layer adaptive optics (GLAO) system for the 2.2-meter telescope on Mauna Kea aiming for high resolution, high sensitivity, and a large field of view using relatively large mirrors. Due to the size and weight of large mirrors, gravity causes deflections on the mirror surface, which distorts the output image. The design of a mount for large mirrors must be carefully considered to support the mirror and limit self-weight deflection. Mirror surface deflections are calculated using various finite element analysis (FEA) software pacakges, i.e. COMSOL, ANSYS, Solidworks and PLOP.

Design Rules for Additive Manufacturing
close

Additive Manufacturing (AM) has increased in popularity as a low-cost, high-precision manufacturing method for rapid prototyping. While these AM methods are capable of quickly producing complex geometries, AM is still subject to notable manufacturing limitations. This research seeks to (1) develop design-for-manufacturing (DFM) rules for existing AM methods, and (2) develop novel additive manufacturing methods and techniques for increase the relevancy of AM technologies.

IPS

Intelligent Plant System
close

The Intelligent Plant System (IPS) project , whose goal is to design and develop a machine that can monitor plant growth in response to climate change. Currently, very limited experimental data is available regarding plant response to changing climate, as it is a difficult engineering problem to create a controlled environment to incubate plant growth over a given subset of independent environmental perturbations. The goal of this design initiative is to create a cost-conscious machine capable of monitoring and controlling carbon dioxide (CO2), ozone (O3), temperature, and humidity levels in an artificial environment. This machine should be scalable to allow for a large number of test subjects to achieve scientific validity of results for all of the control variables mentioned above.

UXS

Unmanned X Systems
close

The Unmanned X Systems (UXS) development group is a Vertically Integrated Project (VIP) aimed towards the advancement of Unmanned Systems technologies. The need for robust software and hardware robot platform(s), often equipped with expensive sensors and instrumentation, creates a high barrier of entry to the field of robotics and unmanned systems. By following the VIP academic framework, the UXS development group aims to engineer robust unmanned aerial, surface, and underwater platforms for practical applications.

Vibration Energy Harvesting
close

Energy harvesting, also known as energy scavenging, is a process by which energy is extracted from the surrounding environment for the purpose of powering small, stand-alone, digital logic devices. Energy harvesting generally entails small scale applications–on the order of 10-10,000 μW/cm^3–providing onboard power for wireless sensor nodes. In these applications a physical wiring scheme defeats the purpose of wireless digital logic, and a finite energy sources (such as a battery) sets a significant limitation on the achievable lifetime of the sensor. From this, there is a clear demand for a power source with a lifetime similar to that of the expected lifetime of the electronic subsystem that it powers–a demand which which the field of energy harvesting aims to meet.

Manoa Astronomical Technologies
close

The Astronomical Instruments Vertically Integrated Projects (VIP) team works on several aspects of precision engineering of telescopes and astronomical instruments. The team is working to build a 12” optical telescope as a platform for testing instruments. This project will also help to develop the core competency and understanding of optical physics necessary to drive the engineering design of other specific instruments.
