Applications outside the Earth's atmosphere are a prominent use scenario for Unmanned Systems from ACTIVEROBOTICX. It is dangerous to send humans to space, for them to be in space, and to return them to Earth.
Maintaining reliable operation of an Unmanned System in space presents many unique challenges for ARX engineers. The vacuum of space prevents the use of most types of lubricants. Temperatures can vary in the extreme depending on whether the Unmanned System is in the sun or shade. And, there is almost no gravity. These factors present an opportunity rather than a challenge and could lead to some unique designs from ARX.
Requirements can be called extreme relative to the application of Unmanned Systems on Earth.
Depending on the application (either orbital or planetary), Unmanned Systems in space will be designed with mobility, be able to manipulate, grip, rove, drill and sample. Dependent on the mission and distance from Earth or the operator, Unmanned Systems may have a level of autonomy, ranging from direct teleoperation by an operator to fully autonomous operation. Depending on the degree of autonomy, an Unmanned System in space could act as a robotic agent to carry out various tasks using teleoperation up to the semi-autonomous activity, or as a robotic assistant using semi to fully autonomous operation that can assist astronauts in the efficient and safe performance of tasks. As already well proven on the Lunar and Mars missions an Unmanned System can be applied as an explorer that is capable of exploring unknown territory in space using fully autonomous operation and a wide range of sensors and tools.
