Dexterous robotic limbs and mechanisms on better artificial muscles. Superior artificial muscles make it possible to have stronger limbs and dextrous movements for robots. Building a robot becomes much cheaper as well. 
Imagine a robot under 1000 dollars as elegant and graceful as a human or maybe even better. 
Having such a complex system with many muscles has its own challenges of implementation. It makes it almost impossible to program every single muscle for motion planning. Therefore we use AI(Reinforcement Learning) to teach the robots appropriate skills which is how we avoid the sophisticated programming.
With these advantages we apply the skills to various commercial applications.
