Robots are ultimately going to be a part of daily lives in the future. To make robots do what you desire, they need to have the appropriate hardware and have to be programed so as to fulfill the need of the work.
The greatest challenge when it comes to robots is to create robots that can move around in the human world, performing tasks that are beneficial to people and perform a task to the desired satisfaction autonomously.
Although a lot of robots in todays world are autonomous but they are highly constraint to the surrounding. They rely solely on the sensor inputs and the program they have in their memory. If you put the robot in a never before situation, the robot has to plan/process a strategy all over again.
