Puppet control mechanism

Abstract

An apparatus comprises a puppet device. The apparatus also comprises a control mechanism operably connected to the puppet device to control movement of the puppet device. The control mechanism comprises a material having a material index of refraction that substantially matches a fluid index of refraction of a fluid in which the puppet device and the control device are positioned such that the control mechanism is rendered substantially invisible. Further, another apparatus comprises an object. The apparatus also comprises an actuator that is operably connected to the object and moves in a fluid environment based upon movement of a control mechanism that interacts with the actuator in the fluid environment, the control mechanism comprising a material having a material index of refraction that substantially matches a fluid index of refraction to render the control mechanism substantially invisible in the fluid environment.
