Robotic Search and Rescue
I built a robot that is able to improve safety in mines. The robot takes a series of sensor readings, do 3D mapping to compare deteriorating physical conditions in time, detect CO and CH4 levels and record video footage. All of this information is then sent back to the user. The project aims to build a robot that could decrease the amount of casualties in mines due to gas or instability. A strict engineering process, which comprised researching different features on a robot, was followed. A prototype robot was built, tested and improvements made. Some of the challenges faced, while building the prototype robot, included manoeuvrability over any type of terrain, even rough and rocky terrain. Choosing the correct driving mechanism (wheels, tracks, suspension and steering) also proved to be a very important feature that had to be kept in mind. The sensors used included, a temperature, humidity, carbon monoxide gas, as well as a methane gas sensor. A Gyro, Accelerometer and compass for easier navigation were also used. Two cameras which included a front camera for navigation and 3D mapping as well as a back camera for navigation were installed. The robot was tested over various terrains, it was able to retrieve sensor data and all of the engineering goals were reached. After the robot was built it was tested on various terrains. The robot achieved all of the engineering goals. The sensors was able to give readings, the robot 3D mapped an area and was also able to manoeuvre over rough terrain.
Antibacterial Properties of Mānuka
Antibacterial Properties of Mānuka Mānuka (Leptospermum scoparium) is a native 紐西蘭 plant that has long been used by indigenous Maori for its medicinal and therapeutic properties, yet is relatively unknown to science. Many of our native species may contain novel compounds with practical applications in our lives. Research indicates that mānuka has anti-microbial, anti-fungal, herbicidal, insecticidal and anti-bacterial properties, and suggests that compounds similar to Grandiflorone (ß-triketones) cause these effects. This project investigates the antibacterial properties of mānuka leaves, using the bacteria Photobacterium phosphoreum for biological testing. With the recent rise in multidrug-resistant bacteria, it is now more vital than ever to utilize traditional knowledge to inform research and development of innovative new antibiotics, antimicrobials and similar biologically important compounds.
