Single camera depth control in micro class ROV

Navigation is one of the main challenges in an underwater vehicle. To measure and sustain the depth in the micro class remotely operated vehicle (ROV) robot is one of the main demands in the underwater robot competition. There are many sensors that can be used to measure the depth; one of the sensors is using a single camera sensor. In this works, camera-based depth control is developed and evaluated for micro class ROV, namely as fitoplankton SAS ROV. Fitoplankton SAS ROV is a micro ROV prototype with six thrusters. To maintain the depth position, a PID control system with a camera-based depth sensor as the input of the setpoint is used. Moreover, the method for the camera to measure the distance is using the triangle similarity method. In this paper, the experimental scenario is using the rectangular marker to measure the distance, and the value of the depth is processing in the ground control station (GCS). The GCS will send the thruster value to control the depth, which depends on the PID control system. The experiment results show an average of depth accuracy of 95.74% to the depth setpoint

FIToplankton: Wireless Controlled Remotely-operated Underwater Vehicle (ROV) for Shallow Water Exploratio

Remotely Operated Vehicle (ROV) for underwater exploration is typically controlled using umbilical cable connected to ground control station. Unfortunately, while it’s used for power distribution and data transmission, it also obstruct the movement of ROV especially for shallow water (<50 cm). This paper proposed an alternative method for controlling ROV using wireless remote control system. This work also aims to explore the possibility of using RF wireless technology between 420-450 MHz as underwater communication system. Furthermore, the control system was used to manage actuators i.e. DC motor and bilge pump for maneuvring and picking small size cargo. To help the ROV to hold on a desired, Inertial Measurement Unit (IMU) is installed on board ROV within maximum deviation 0.2 m/s2. The prototype of the system has been successfully implemented and evaluated to confirm the  functionality and the feasibility of the proposed approach

Psychological Encouragement for High School Students in Preparation for Online Learning During Covid-19

Psychosocial is commonly defined as referring to a relationship that is close in both psychological and social factors. Emotional and cognitive development, as well as social factors such as interpersonal relationships and the community in which a person lives all influence a person's psychological well-being. Psychosocial is focused on the interpersonal aspects that exist alongside psychological aspects (thoughts, emotions, and behavior) (social relations, traditions and culture). Initiated psychological encouragement (commonly referred to as DPA) is also known as PFA (PFA). Psychosocial encouragement is a type of DPA. DPA aims to reduce the detrimental effects of stress, to help individuals recover from disasters, and to assist in the process of their return to normal. A crisis situation is an ongoing (or expected) event that places people, groups, communities, or societies in an unstable and dangerous position, which then impacts those people, groups, or societies. There are both positive and negative impacts that teachers, students, and also parents have to face and deal with during a COVID-19 pandemic. Stress and pressure can arise naturally, for everyone, when someone is in an unpleasant/crisis situation. Emotional expressions, such as crying in children aged 0-3 years, or other non-adaptive behavior, such as aggressive or tantrums, are common indicators of stress in students (venting anger or excessive emotional outbursts at a certain age because there are unfulfilled wants or needs)
