<p>A drive arrangement for a mobile robot comprises a transmission unit for transmitting drive from a motor unit (100, fig 7) to a drive shaft (102, fig 7) extending from the transmission unit along a drive shaft axis, a swing arm 92 coupled to the transmission unit so as to swing angularly about an axis of the drive shaft (102, fig 7), a drive sprocket 94 mounted to the drive shaft (102, fig 7) and a driven pulley 96 mounted on a portion of the swing arm 92 remote from the drive shaft (102, fig 7) and being rotatable about an axis parallel to the drive shaft axis. A track 98 is constrained around the sprocket 94 and the pulley 96, wherein the sprocket 94 and the pulley 96 are arranged such that the track 98 presents an inclined driving surface.</p> |
