A two degree-of-freedom positioning and manipulating apparatus is provided. The apparatus includes a first driven member rotatable about a first driven axis, a first driver member coupled to a first driven member for rotating the first driven member about the first driven axis, and a link member fixedly connected to the first driven member. The apparatus further includes a second driven member rotatably mounted to the link member for rotating about a second driven axis, with the second driven axis generally parallel to the first driven axis, and a second driver member coupled at a drive point to the second driven member for rotating the second driven member about the second driven axis. The drive point is generally coincident with the first driven axis.
