An ambulatory robot system (10) comprises two robot units (11, 12) each provided with attaching means for use in selectably attaching the respective unit to and detaching that unit from a surface, a coupling linkage (13), which is composed of articulated limbs (16,17), coupling the units together to be relatively movable for varying their positional relationship, and drive means (30) for displacing the coupling linkage to produce the relative movement when either one of the units (11,12) is detached from a surface while the respective other unit (12, 11) remains attached to a surface. The flexibility and utility of the system are enhanced by providing for the detached unit to be rotatable relative to the attached unit to allow the detached unit to travel on a path around an axis (A) of the attached unit.

COLLISION AVOIDANCE SYSTEM FOR A MOBILE DEVICE CAPABLE OF AUTONOMOUS TRAVEL
A mobile device (10) capable of autonomous travel comprises drive means (12, 13) to provide movement of the device over a surface and an obstacle detecting and movement influencing system (15, 16, 17) to detect an obstacle (20) in the path of the device and in response to detection of an obstacle to control the drive means to influence movement of the device. The obstacle detecting and movement influencing system comprises a pneumatic element (15) which is positioned on a body (11) of the device to face in the forward direction of movement of the device and which is resiliently compressible on contact with an obstacle (20). The device (10) includes a control unit (18) responsive to sensing by a sensor (17) of the contact to then control the drive means (12, 13) so as to cause travel of the device in the direction of forward movement to be arrested and subsequently resumed in that direction after a delay, during which the device may remain stationary, execute reverse travel and/or execute a bypass routine.
An electrical connector (10) comprises a socket (11) with an annular recess (12), which has an electrically conductive outer annular wall surface (13a) and an electrically conductive inner annular wall surface (13b) electrically isolated therefrom, and a plug (18) with an annular projection (21), which is receivable in the recess (13) of the socket to be spaced from the outer and the inner annular wall surfaces (13a, 13b) of the recess and which has an electrically conductive outer annular wall surface (21a) and an electrically conductive inner annular wall surface (21b) electrically isolated therefrom to establish separate electrical paths when the projection (21) is fully received in the recess (13). The connector further comprises a first resilient electrically conductive annular contact element (25) retained in a groove (26) in the outer annular wall surface (13a) of the recess and resiliently compressible to produce an electrical connection of the opposing surfaces (13a, 21a) of the recess and projection and a second resilient electrically conductive annular contact element (27) retained in a groove (28) in the inner annular wall surface (13b) of the recess and resiliently compressible to produce an electrical connection of the opposing surfaces (13b, 21b) of the recess and projection.

A vehicle traction element (10) for providing traction relative to a surface over which a vehicle equipped with the element is to travel comprises a rotary or circulatory member, especially a wheel (10a), which has a periphery (12) and is provided at the periphery with a series of resiliently deflectable surface-engaging arms (11). The arms (11) are equidistantly spaced around the periphery (12) and have the same shape and orientation. In particular, each arm has a root (13) at, and a tip (14) remote from, the periphery (12) and each arm comprises an inner curved portion (15) starting at the root and departing from the periphery at an acute angle (a) on a concave side (15a) of that portion (15) and an outer curved portion (16) ending at the tip (14) and curved in opposite sense to the inner curved portion (15). The resiliently deflectable arms (11) allow relatively smooth motion over normal surfaces, but can function similarly to claw-tipped legs to lever the wheel over an obstacle.
