Abstract: A fluted drill comprises, in axial sequence, a body portion, and a cutting portion. The cutting portion comprises two or more cutting edges, with each cutting edge extending from a distal end of the cutting portion, along the cutting portion towards the body portion, to the body portion.Each cutting edge has a first rake angle at the distal end of the cutting portion, progressively increasing to a third rake angle at a proximal end of the cutting portion. Each cutting edge has a first uncut chip thickness at the distal end of the cutting portion, progressively decreasing to a third uncut chip thickness at the proximal end of the cutting portion.

Abstract: An apparatus for coating a surface of a substrate includes an evaporant source disposed within an open environment including air at atmospheric pressure. The evaporant source includes a coating material. The apparatus further includes an energy beam source disposed within the open environment and configured to emit at least one energy beam that impinges on an emission region of the evaporant source to form a vapour plume at the emission region. The vapour plume includes the coating material of the evaporant source. The apparatus further includes a fixture configured to position the evaporant source relative to the substrate within the open environment, such that a maximum distance between the emission region of the evaporant source and the surface of the substrate is less than or equal to 10 cm.

Abstract: A hyper-redundant manipulator for insertion into an area of interest through an aperture is shown. The hyper-redundant manipulator comprises a plurality of individually-lockable sections, each of which comprise a plurality of segments having positions that are adjustable relative to each other so as to adopt a pose. A respective locking mechanism is located in each section and is configured to switch between a locked condition in which the pose of the segments in the respective section is locked, and an unlocked condition in which the pose of the segments in the respective section is not locked. A plurality of actuators common to all of the sections are provided to adjust the pose of the segments in sections with a locking mechanism in an unlocked condition.

Abstract: Methods of controlling a hyper redundant manipulator, the hyper redundant manipulator including: a plurality of sections comprising a first free end section and a second end section; and a base arranged to receive the plurality of sections in a coiled configuration, the base being coupled to the second end section of the plurality of sections, the method comprising: receiving a trajectory for movement of the plurality of sections; determining an error in position and/or orientation relative to the trajectory for one or more sections of the plurality of sections, the error being caused at least in part by the coiled configuration; and controlling movement of the one or more sections using the determined error to compensate for the error in position and/or orientation of the one or more sections.

Abstract: A method of controlling at least one of a first robot and a second robot to collaborate within a system, the first robot and the second robot being physically separate to one another, the method including: receiving sensed data associated with the second robot; determining position and/or orientation of the second robot using the received sensed data; determining an action for the second robot using the determined position and/or orientation of the second robot; and providing a control signal to the second robot to cause the second robot to perform the determined action to collaborate with the first robot.
