Useful robots have been a dream of many and science has been continually trying to create machines that can tackle problems that may be too dangerous or too monotonous for humans to do. Automation has changed manufacturing over the last few decades and the science of robotics is advancing at a rapid pace.
Forbes takes a look at future technologies that will make a significant change in our lives.

First is the DaVinci Surgical System
It can be used in a variety of surgical procedures, such as gastric bypass surgery, removal of the prostate and mitral valve repair. Benefits include fewer, more precise cuts and less bleeding and it never gets fatigued.

T52 Support Dragon
Made to help firefighters and other rescue personnel. Its two hydraulically powered arms can hold about a half-ton each, strong enough to move steel girders and other debris, or hold up a collapsing wall or ceiling. It can be controlled either by a human in the cockpit or remotely via mobile phone.

Robot RX
Eliminating medical errors is the goal and this robot is less likely to make mistakes filling prescriptions than human pharmacists. Computers continue to monitor the medicines.

Experimental Bionic Arms
Implanted electrodes in the brain can help direct the movement of a robotic arm.

Big Dog
This canine robot is being built for the U.S. Department of Defense, would have four legs and would run alongside troops on their missions, carrying ammunition and performing basic reconnaissance tasks.
