A drive system set comprises diablo type drive rollers 10 which engage with a member 11. When viewed along a reference axis (12, fig 1) extending through contact points (13) between the rollers 10 and the member 11, and through a member axis (14), drive axes (15) of the rollers 20 are arranged at acute angles (α) to the member axis (14). Rollers 10 are rotatably mounted on a shaft 18 held in bearing housings 21 and 22 forming part of, or attached to, base plate 23 and cover plate 24 which forms a cradle. A motor (37) having a pinion (38) is mounted to a support bracket (32) which is rotatably fixed to the base plate 23 via a bearing plate 25. Pinion (38) engages gear surface 39 on the base plate 23 so that the motor (37) drives the cradle relative to the bracket (32). Two sets are mounted back-to-back to the member 11 so that by varying speeds and directions of the motors, combinations of linear and rotational drive can be achieved.
