Summary/ Reader response final draft

The Deep Trekker website (2022a) promotes the usage of underwater Remotely Operated Vehicle (ROV), DTG3. Among its functions, it is pointed out that the robot can conduct intensive observation under rough conditions and send live feedback to the user. It features an enhanced 4K camera, sonar system, Ultra-short baseline (USBL), and three precision thrusters. The enhanced 4k camera demonstrates the ideal underwater inspection experience paired with premium lenses and an algorithm unique to Deep Trekker(Deep Trekker, 2022a). Its sonar system allows DTG3 to assess the surrounding environment for navigation and inspection purposes. While the USBL system can be understood as a GPS to aid navigation. It is reported that the precision thruster on the machine enables the ROV to accurately make vertical movements(Deep Trekker, 2022a). One crucial trait of DTG3 itself is its small size which allows the ROV to inspect tight spaces. For such a small size, its battery has a runtime of up to 8 hours(Deep Trekker, 2022a). This ROV is an all-rounded piece of equipment that is applicable to use even in the harshest conditions. 

I believe that the DTG3 ROV will prove to be one of the most efficient ROVs for underwater inspection and exploration in the market because of its maneuverability, advanced camera system, and enhanced navigation.

DTG3’s maneuverability allows for extremely fine movements and controls due to various features. According to the Deep Trekker website (2022a) DTG3 only measures 325mm x 258mm x 279mm. This allows the device to reach into crevices that bigger ROVs cannot reach. With the help of its 3 precision thrusters, it enables precise vertical movements. They come with sensors that integrate seamlessly with Deep Trekkers' unique BRIDGE technology. These thrusters paired with BRIDGE technology give the user access to the auto-depth holding function (Deep Trekker, 2022d). This function is useful when the user wants to inspect parts only at a certain depth. Besides these features, the shell and precision thrusters can be rotated for the ROV to move freely in any direction (Ocean Innovations, 2022). The combination of these features allows the user to ‘see’ and move underwater freely which greatly contributes to its maneuverability, crucial for exploration and inspection underwater.

DTG3 has an advanced camera system that makes this ROV more efficient underwater. Equipped with the 4k camera system, besides the clear coloring and imaging, the camera is also able to rotate at an angle of 270 degrees(Deep Trekker, 2022a). The Deep Trekker website (2022a) also states that the camera system also comes with a lighting system that provides a brightness of up to 1000 lumens, allowing user to see clearly even in the murkiest water. Through BRIDGE technology, a lot more can be accomplished. Unlike usual wireless ROVs, the DTG3 ROV has been observed to have almost no delays when it comes to communication (Deep Trekker, 2022d). The user will not experience any lags during the operation of the ROV which is crucial when operating in real time. With the integration of the 4k camera system and the lighting system by BRIDGE technology, this advanced camera system makes underwater inspection and exploration easier.

DTG3’s enhanced navigation system allows the user to control the ROV with more efficiency. Navigating through the ocean can be hard because of the properties of water. When underwater, light does not travel as well as in air, unlike sonar (Morin, 2019). A sonar system is used underwater for imaging, exploring, and mapping purposes(Deep Trekker, 2021b). According to Deep Trekker (2021b) sonar systems can also be used to identify corrosion and deformities as well as to analyze complex structures. This feature alone allows for easy navigation and inspection underwater. The Global Positioning System does not work underwater, without this feature, the user is unable to know the exact position they are at (Morin, 2019). The USB-L system provides real-time tracking so that the user can identify the exact position of the ROV and locations where faults are found. These two technologies are integrated together to enhance the navigation experience. The user will be able to explore underwater more efficiently with the sonar system and positioning system.

One flaw that DTG3 has is that the system itself does not support route planning and the waypoint function for easy accessibility. Route planning is an important function that can be used to automate inspections. The waypoint function can help user automate the inspection of areas where faults are frequently observed. These two functions can greatly increase the efficiency and productivity brought about by the DTG3 ROV. However, it is stated that Deep Trekker will be working on future updates to address the waypoint function (Deep Trekker, 2022c). 

Weighing both options, I think that the pros outweigh the cons. The excellent maneuverability, advanced camera system, and enhanced navigation make the DTG3 one of the best choices in its class for underwater inspection and exploration purposes.

Letter of introduction

 September 07, 2022 Dear Professor Brad, My name is Jau Hui Si, and I am writing this letter to share more about myself. I graduated from Singapore Polytechnic with a diploma in electrical and electronics engineering. Before studying full-time at the Singapore Institute of Technology, I worked as a software tester under Venture Corporation for three short months. Since young, I have always been fascinated by the various high-end technology shown in movies. However, my experience in a semiconductor manufacturing company was what solidified my decision to specialize in robotics back at Singapore Polytechnic. I firmly believe that humans aided by robots can make a positive impact in all kinds of industries. One weakness I have in communication is being too soft-spoken. Being an introvert, I find it hard to communicate with other people. It has been an issue that I have been working on for quite some time. To improve on this aspect, I have been taking the initiative to communicate with...

Critical Reflection

Over the past 13 weeks, I have discovered more about myself. Looking back at the goals I set for myself at the start of this module, I believe that I have met most of my goals throughout this module.  Module Learning One factor behind most of my weaknesses in communication that I identified was my introverted nature. This module helped me know more about my classmates so that I would not feel overly nervous when I speak. My first goal was to become more outspoken. Professor Blackstone patiently helped me overcome this weakness of being too soft-spoken throughout these 13 weeks by getting me to the class and by initiating small talk. I realized that over the past few months, I felt comfortable initiating conversations and I felt less shy when I talk to people around me. I am thankful for the opportunities Professor Blackstone gave me to walk out of my comfort zone.  Besides overcoming my weaknesses in communication, I have also learned more about communication and critical thin...

Summary draft 1 for Deeptrekker (With Juergen)

Deeptrekker promotes the usage of underwater Remotely Operated Vehicle (ROV), DT640 Utility Crawler (Deep Trekker, 2022) . Among its functions, the robot has the capability to conduct intensive observation under rough conditions and send live feedback to the user. In terms of features, the robot is coupled with an enhanced 4K camera, standard USBL and a precision thruster. The enhanced 4k camera allows users to view under low light conditions and provides enhanced clarity with its underwater correction. Like a GPS system, the Ultra-short Baseline (USBL) position system is software where it calculates the positioning of the ROV. Consisting of a transducer on the surface of the water and a transponder on the ROV, it allows accuracy of 20cm from itself. As mentioned on the webpage, the precision thruster on the machine enables the robot to maneuver vertically with much stability. Accompanied with a rotating camera, the GT63 can provide 270 degrees view vertically upwards and downwards of ...
