Robonauts and automated vehicles in general can resolve by themselves only very specific types of problems that they are programmed to resolve in advance. While astronauts can adapt and manage to counter problems not included in training.
Robonaut 2 is currently working on International Space Station. NASA will test how Robonaut 2 works in space. If it will fulfil NASA’s hopes, it will remain in the International Space Station and will be given more jobs to do.
Unfortunately developing autonomous space vehicles and robots is a hard and costly process. For most missions it is cheaper to train astronauts than develop a robot that can perform the necessary tasks. However, autonomous technology has a great potential to prove itself in the long run, because while development costs are extremely high, robots can spend a much longer time in spacethan humans without the need to return on Earth or resupply. This may make operational costs significantly
