The commercial market, however, is largely lacking in robotic technology which could potentially revolutionize many everyday tasks undertaken by humans. This thesis describes a design integrating robotic technology with a common office chair. The requirements of such a chair are discussed, as well as the resulting design decisions. The advantages and drawbacks of the Voice Coil Actuators used in the design are also discussed. A prototype control system, enabling ergonomically beneficial motion is described and analyzed.
