“…Here, GPIO pins PB0 and PB1 of the STM32 microprocessor are connected to the pump driver, and modulated square wave signals (according to Eqs. (1) and (2) above, and particularly with regard to Figure 6) are input to achieve thrust control [34], [35]. The pump power is set at 75% of the rated power to save energy when no light sensor is triggered.…”

This article presents a specialized control system for an unmanned surface cleaning vessel (USCV) employing a pump-valve propulsion system. The system has three operational modes, including manual remote-control mode, self-automated cruise mode, and self-locking remote-control mode. In the manual remote-control mode, users remotely control the vessel by means of a motion-control joystick. In the self-automated cruise mode, the control system is capable of detecting obstacles and automatically controlling the pump-valve propulsion system in response to feedback signals from sensors. The selflocking remote-control mode functions similarly to the first mode, except that the joystick controls the vessel motion in accordance with a single established joystick-actuation pattern. The control system is supported by a commercially available remote controller with wireless communication technology. The functionality of the combined control and pump-valve propulsion system is verified by computational fluid dynamics simulations and experimental tests conducted using a prototype USCV. The combined control and pumpvalve propulsion system is demonstrated to be a cost-effective, simple, and innovative platform that is suitable for use with USCVs. INDEX TERMS USCV, pump-valve propulsion, operational modes, CFD, motion states.

“…Multihull designs have huge improvements in stability over monohull designs concerning the roll and wave of the vessel [4]. This increased stability is a result of multihulls typically having a wider footprint than monohulls.…”

This paper presents a prototype of a low-cost Unmanned Surface Vehicle (USV) that is operated by wave and solar energy which can be used to minimize the cost of ocean data collection. The current prototype is a compact USV, with a length of 1.2m that can be deployed and recovered by two persons. The design includes an electrically operated winch that can be used to retract and lower the underwater unit. Several elements of the design make use of additive manufacturing and inexpensive materials. The vehicle can be controlled using radio frequency (RF) and a satellite communication, through a custom developed web application. Both the surface and underwater units were optimized with regard to drag, lift, weight, and price by using recommendation of previous research work and advanced materials. The USV could be used in water condition monitoring by measuring several parameters, such as dissolved oxygen, salinity, temperature, and pH.
