Final Summary / Reader Response Draft of Deep Trekker DTG3 ROV

The webpage “DTG3 Package” (2022) promotes one of Deep Trekker’s creations, an underwater DTG3 remotely operated vehicle (ROV). The ROV is a highly functioning rover since it is loaded with a variety of functions and capabilities. One feature highlighted in this Deep Trekker DTG3 website (2022) is incredible flexibility to manoeuvre underwater due to its rover design and light weight of 8.5kg. Another exceptional quality of the Deep Trekker is its stability, which is supported by its accurate thrusters and an auto-stabilization capability included in the BRIDGE software (DTG3 ROV, 2022). Aside from its basic functions, it is capable of customizing with multiple add-ons to boost its functionality. Commonly used add-ons are mostly various visual sensors for diverse types of sea inspections, sample extracting or collector tools, and additional existing parts of the DTG3 to increase its agility (ROV Buying Guide | Everything You Need to Know Before You Buy, 2022).

Deep Trekker's DTG3 ROVs might easily rank as one of the most effective ROVs for usage in inspecting underwater coastal marine life with all these characteristics and capabilities. Although its expense is a drawback, this is supported by its sophisticated camera system and ROV body's stability and flexibility.

One of the most crucial designs for the ROV's camera system is one that allows the user to record or analyse underwater coastal marine life. According to the Deep Trekker’s website (2022), the DTG3 comes with a full high-definition (HD) camera, which is a choice of upgrade to a camera with a resolution of four times of a full HD camera, also known as 4 Kilo(K) or thousand. Its manufacturing company also stated that it has a camera rotation limit of 270 degrees, which ability to observe most of the tightest angles while maintaining a clear image or video (ROV Buying Guide | Everything You Need to Know Before You Buy, 2022). The DTG3 also has BRIDGE technology, which uses an algorithm for image stability and clarity under various real-world circumstances (Powered by BRIDGE Technology, 2022). All of this might be corroborated by an experiment done by Khorgane (2021) on the research of coastal bivalves, which demonstrates Deep Trekker is superior at capturing the view since the camera of the Chasing Dory TX, a different yet similar class ROV, had poor video quality. A more effective camera system will also increase the ROV's effectiveness, which represents the effectiveness of the DTG3 in examining aquatic coastal species.

Even though the ROV should have more sophisticated features to be able to check marine life, its body weight complicates underwater manoeuvrability and stability. Anwar et al. (2016) state that when a vehicle approaches the density of the water, its weight will have an impact on its density. This relationship can be seen in the graph of a ROV with water pump chambers pumps in water to raise its weight (Anwar et al., 2016). As density is directly proportional to weight, a higher weight will result in a higher density of ROVs, which will cause a sinking effect, reducing their mobility and flexibility as more force is needed to manoeuvre the ROV (Yadav, 2022). The ROV's stability may also be impacted by weight. The buoyancy line must be parallel to the weight of the ROV's body (Buoyancy & Stability, 2016). To do it, the ROV needs neutral buoyancy by density according to Sahili et al. (2018), which should be equivalent to the water's density of about one thousand kilograms per cubic meter. Considering all of that, the ROV's density is crucial and is determined by the density of the ROV's weight and material, in this instance acrylic, one of the least dense yet stable materials (Physical Properties of Acrylic, n.d.). The DTG3 is ideal for retaining stability and flexibility underwater when examining coastal marine life because of the low weighted density of the acrylic material, which makes it efficient.

However, DTG3 is more expensive than its rivals, so customers will need to reconsider purchasing one. For example, the Chasing Dory is cheaper than the DTG3, with each costing USD $649 and $8500, respectively (ROV Buying Guide | Everything You Need to Know Before You Buy, 2022) (CHASING DORY UNDERWATER DRONE | The most affordable and portable underwater drone, n.d.). Users must consider this significant pricing disparity given that both allow users to view underwater aquatic life. Even so, people will incline to adopt DTG3 because of its superior specs. Khorgane (2021) claims that the DTG3 was used for his research on employing a ROV to check coastal bivalves since it had a longer cable, a stronger engine, and higher video quality than the Chasing Dory ROV.

In summary, despite being the most expensive ROV on the market, the Deep Trekker's DTG3 is still the most effective for examining marine life along the coast because of its outstanding camera system, stability, and flexibility brought on by its density.
