(US10751872) The invention claimed is: 1. An underwater snake robot comprising:   a first end and a second end;   a plurality of links that are connected to one another in a sequence between the first end and the second end by joint modules for generating a flexural motion of the robot, wherein the joint modules actively drive movement of the links relative to one another and are actuated by one or more actuators and the robot flexes at two or more joints to thereby generate an undulating motion;   multiple thrust devices located at different points along the length of the robot for applying thrust to the robot for underwater propulsion and optionally for guidance, wherein the multiple thrust devices comprise at least one thruster module in the sequence of links between the first end and the second end of the snake robot; and   at least one tool, or at least one connection point for a tool, attached to the robot;   wherein the thrust devices enable movement of the entire robot in translation, 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 autonomous underwater vehicle with a single elongate body structure formed by the sequence of links. 2. An underwater snake robot as claimed in claim 1, wherein the thrust devices comprise a thrust device for applying lateral thrust and/or a thrust device for applying longitudinal thrust. 3. An underwater snake robot as claimed in claim 2, comprising a thrust device for applying lateral thrust, this thrust device being a thrust module with one or more thrusters. 4. An underwater snake robot as claimed in claim 3, wherein the thrust module comprises thrusters oriented in two perpendicular directions. 5. An underwater snake robot as claimed in claim 1, comprising a thrust device with a controllable direction of thrust. 6. An underwater snake robot as claimed in claim 1, comprising a thrust device for applying a longitudinal thrust. 7. An underwater snake robot as claimed in claim 1, wherein the thrust devices are capable of moving the robot in translation and/or rotating the robot in roll, pitch and/or yaw. 8. An underwater snake robot as claimed in claim 1, wherein the flexural motion generated by the joint modules is an undulating motion capable of propelling the robot. 9. An underwater snake robot as claimed in claim 1, wherein the robot comprises at least three links joined by joint modules allowing for articulated motion. 10. An underwater snake robot as claimed in claim 1, wherein the joint modules each permit relative rotation in one or more planes. 11. An underwater snake robot as claimed in claim 1, wherein the joint modules each permit relative rotation in the yaw, pitch and roll directions of the robot. 12. An underwater snake robot as claimed in claim 1, comprising one or more buoyancy element for increasing and/or decreasing the buoyancy of the robot. 13. An underwater snake robot as claimed in claim 1, wherein the robot includes a tool or connection point for a tool at the front end of the robot, at a front module, so that the tool is, in use, located at the front end of the robot. 14. An underwater snake robot as claimed in claim 1, comprising multiple tools and/or connection points. 15. An underwater snake robot as claimed in claim 14, comprising a tool or connection point at the front end of the robot and a tool or connection point at the stern of the robot. 16. An underwater snake robot as claimed in claim 1, comprising an inspection tool, for example a camera. 17. An underwater snake robot as claimed in claim 1, comprising a manipulator tool. 18. An underwater snake robot as claimed in claim 1, comprising a combined suction and thrust device, wherein the combined suction and thrust device uses the same driving mechanism to provide both of a first mode of operation where thrust is provided for propulsion and/or guidance of the vehicle and a second mode of operation where suction is provided for holding the vehicle against another structure. 19. An underwater snake robot as claimed in claim 1, wherein the robot is a snake robot. 20. An underwater snake robot as claimed in claim 1, wherein the robot comprises a front module with the tool or the connection point for a tool, a stern thrust device at the opposite end of the robot to the front module, multiple links between the front end and stern end, the links coupled by joint modules, and one or more thrust modules along the length of the robot for producing lateral thrust. 21. An underwater snake robot as claimed in claim 1, wherein the joint modules are enclosed by oil filled bellows. 22. A method for control of an underwater snake robot as claimed in claim 1, the method comprising: controlling the joint modules and the thrust devices in order to move the robot into a required orientation and/or location; wherein the joint modules are used to generate a flexural motion that can propel the robot and/or used to adjust the shape and configuration of the robot; and wherein the thrust devices are used to move all of or parts of the robot in translation and/or in rotation. 23. A method as claimed in claim 22 comprising: using the joint modules to adjust the robot configuration and using the thrust devices to translate and/or rotate the robot, to move the robot and/or its tool(s) to a required location and/or orientation. 24. A method as claimed in claim 22, wherein the robot includes a thrust device for applying a longitudinal thrust and the method comprises: using the longitudinal thrust to propel the robot and using the joint modules to adjust the shape of the robot and thereby control the position and/or orientation of the robot and/or its tool(s). 25. A method as claimed in claim 22, comprising determining the orientation of all of the joint modules and thrust devices, determining a vector for thrust from each thrust device, and thereby determining required thrust forces and/or joint module adjustments to achieve a required change in orientation and/or location of the robot and/or its tool(s). 26. A computer programme product comprising a non-transitory computer readable storage medium readable by a computer and storing instructions that when executed on a data processing device will configure the data processing device to control an underwater snake robot as claimed in claim 1 in order to perform a method comprising:   controlling joint modules and thrust devices in order to move the robot into a required orientation and/or location;   wherein the joint modules are used to generate a flexural motion to propel the robot and/or adjust the shape and configuration of the robot; and   wherein the thrust devices are used to move all of or parts of the robot in translation and/or in rotation.
