Abstract: A disinfection apparatus, typically an autonomous or semi-autonomous robot which has a germicidal light source, a controller for controlling emission of germicidal light from the germicidal light source and a moveable support to which the germicidal light source is attached which is moveable across a surface. The apparatus may also have a detector which detects the presence of an object in the vicinity of the apparatus wherein the controller controls the direction of germicidal light from the light source in response to the detection of one or more said object.

Abstract: A robot is provided, the robot comprising a body carrying a first drive arrangement, a second drive arrangement and a stabiliser. The robot further comprises actuators operable to cause relative movement of the first drive arrangement, the second drive arrangement and the stabiliser, and to drive the first and the second drive arrangements. The robot is arrangeable in first, second and third configurations each having static stability. In the first configuration, the stabiliser and the first drive arrangement are arranged to contact the ground. In the second configuration, the stabiliser and the second drive arrangement are arranged to contact the ground. In the third configuration, the first and the second drive arrangements are arranged to contact the ground. No other ground contacting point is involved in conferring said static stability in said configurations.

Abstract: The invention provides a control interface configured to cooperate with a vehicle, such as a wheelchair or mobile robot, said interface comprising at least one sensor is adapted to detect the presence of at least one finger of a user and to act as a switching mechanism between manual and autonomous control of the vehicle. The invention provides a highly intuitive and effective means of switching between automatic and manual vehicle control-no user training required. The control interface allows for user to be comfortable in an autonomous vehicle—users can instantly gain full control when needed.
