any task a human being can, so long as they have the proper software. However, the complexity of doing so is immense. Entertainment Humanoid robots have had a long history in the realm of entertainment, from the conception and ideas in the story of Prometheus to the application and physical build of modern animatronics used for theme parks. Current uses and development of humanoid robots in theme parks are focused on creating stuntronics. Stuntronics are humanoid robots built for serving as stunt doubles, and are designed to simulate life-like, untethered, dynamic movement. Several Disney theme park shows utilize animatronic robots that look, move and speak much like human beings. Although these robots look realistic, they have no cognition or physical autonomy. Various humanoid robots and their possible applications in daily life are featured in an independent documentary film called Plug & Pray, which was released in 2010. Demonstrative Though many real-world applications for humanoid robots are unexplored, their primary use is to demonstrate up-and-coming technologies. Modern examples of humanoid robots, such as the Honda Asimo, are revealed to the public in order to demonstrate new technological advancements in motor skills, such as walking, climbing, and playing an instrument. Other humanoid robots have been developed for household purposes, however excel only in single purpose skills and are far from autonomous. Humanoid robots, especially those with artificial intelligence algorithms, could be useful for future dangerous and/or distant space exploration missions, without having the need to turn back around again and return to Earth once the mission is completed. Sensors A sensor is a device that measures some attribute of the world. Being one of the three primitives of robotics (besides planning and control), sensing plays an important role in robotic paradigms. Sensors can be classified according to the physical process with which they work or according to the type of measurement information that they give as output. In this case, the second approach was used. Proprioceptive Proprioceptive sensors sense the position, orientation, and speed of the humanoid's body and joints, along with other internal values. In human beings, the otoliths and semi-circular canals (in the inner ear) are used to maintain balance and orientation. Additionally, humans use their own proprioceptive sensors (e.g. touch, muscle extension, limb position) to help with their orientation. Humanoid robots use accelerometers to measure the acceleration, from which velocity can be calculated by integration; tilt sensors to measure
