As previously described, when a state of equilibrium is approached, and the water velocity decreases, a brief period will occur where the velocity will be insufficient to drive the turbine or energy converting means. As equilibrium is approached, the flow of water through the duct system will decrease in velocity and will theoretically come to a standstill at the moment of equilibrium. Filters 17 and 19 are designed to prevent foreign matter and particles which do enter the duct system from reaching and damaging the turbines or reducing their efficiency. The length of time during which the water will flow from one reservoir to the other will also be affected by the size of the second reservoir. 0 against gravity, buoyancy and/or or water currents; heading changes during on-going movement; changes to the configuration/shape of the robot; and/or propulsive forces used to assist or amplify flexural movements of the robot; amongst other things.
In contrast, underwater robots can move sideways and can push against the surrounding fluid with movement of the body and they do not rely on interaction with a solid surface using friction. The use of an oil filled bellows provides protection from water ingress as well as reducing the risk of snagging of the mechanical parts during use.
The robot of the first aspect effectively provides a manipulator arm without the encumbrance of an ROV or AUV holding the arm. Viewed from a first aspect, the present disclosure provides an underwater snake robot comprising: a plurality of links that are connected to one another by joint modules for generating a flexural motion of the robot; multiple thrust devices located at different points along the length of the robot for applying thrust to the robot for propulsion; and a tool, or a connection point for a tool, attached to the robot; wherein the thrust devices enable movement of the entire robot in translation and the flexural motion and/or thrust devices control the orientation and/or location of the tool with some or all of the links of the robot acting as links of a manipulator arm and wherein the robot is an articulated underwater vehicle.

The links are either rigid or flexible elements, and typically provide the physical connections between the joint modules. Figure 6. The snake robot could alternatively or additionally be provided with longitudinal thrusters mounted at any point along the length of the robot. In addition to the advantages mentioned above, there are additional advantages that arise from the shape and size of the snake robot as compared to traditional ROVs and AUVs. The use of an attachment mechanism is not shown in the Figures but it will be appreciated that it could be added to the examples shown in the Figures. Examples of the more important features of this invention have thus been summarized rather broadly in order that the detailed description that follows may be better understood, and in order that the contribution to the art may be better appreciated. The ROV or AUV must provide a stable base in order to support the arm, and hence such vehicles are relatively large and cumbersome.
Such devices commonly involve the compression of air within storage tanks or pipes for subsequent use in the production of power. The present invention relates to an apparatus for generating power from the continuous rise and fall of tides. More particularly, the invention involves the generation of power from the flow of water in an airtight duct between two reservoirs as the water in these reservoirs seeks a level of equilibrium. In another example, as shown in Figures 9 and 10, the robot has a manipulator tool 14 at the front module, along with sensors/cameras 16, with an inspection tool 12 at the stern. The tool may be any type of tool required for submerged operations, including all types of underwater mapping, monitoring and IMR tools, for example inspection tools such as a camera, or manipulator tools such as a gripper tool. 14 robot. Dolor de espalda cuando duermo . Another possibility is for the device on the subsea structure to take an active part in holding the robot, such as clamping device on the subsea structure and arranged to engage with or clasp part of the robot.
Longitudinal thrust devices could alternatively or additionally be mounted at any point along the robot or at the front of the robot, and this has the advantage of leaving the stern of the robot free for mounting a tool. • Using the gripper or similar tool to grab on to a ROV panel handle or a guideline for docking. This can provide more flexibility when the robot is required to maintain a position relative to a fixed structure, for example so that one of the manipulation tools 14 can work on a part of the fixed structure. The continuous changing of the water level of the natural reservoir due to the movement of the tides will cause water to flow through the duct system as the water level in the second reservoir seeks a condition of equilibrium with the natural reservoir. As the tide comes in, the level of the first reservoir rises and exceeds the level of the second reservoir.

This arrangement could function with or without the use of separate bypass channels and accompanying valving. Also, for the ocean science community including oceanography, biology and marine archaeology, snake robots that are able to swim smoothly without much noise, and that can navigate in difficult environments such as ship wrecks and other confined environments, are very interesting. However, it will be apparent to those skilled in this art that modifications and changes in the apparatus may be made without departing from the scope and spirit of the invention. 1 there is shown an airtight duct system 10 constructed to connect a natural reservoir 12, which is subject to a change in sea level due to tidal action, and a second reservoir 14. The support structure necessary to sustain the duct system is not shown.
