2. Introduction
Computer scientists have created machines that have the balance and agility to walk and run across rough and uneven terrain, making them far more useful in navigating human environments.
Walking is an extraordinary feat of biomechanical engineering. Every step requires balance and the ability to adapt to instability in a split second.
It requires quickly adjusting where your foot will land and calculating how much force to apply to change direction suddenly.

3. A simple agile robot can have more than 5000 parts in it to make it move, walk, and dance.
Agile robots have very powerful hydraulics to move its hands, legs, neck, fingers, chest, face etc.
It is not important that agile robots must have legs, arms and other parts to move itself. Some agile robots can have tires instead of legs to move.
As we are talking about robots and engineering how can we forget about power source which will provide it enough power to move.
The bigger robots we have the more electricity we will need to power it and to do a lot of works to help humans.

4. Evolution
Currently there are three robots which are very popular around the world named as “Atlas”, “BigDog”, “ASIMO” and “QRIO”.
Atlas.
Atlas is a bipedal humanoid robot primarily developed by the American robotics company Boston Dynamics.
With funding and oversight from the United States Defense Advanced Research Projects Agency (DARPA), an agency of the United States Department of Defense.
The 6-foot (1.8 m) robot is designed for a variety of search and rescue tasks, and was unveiled to the public on July 11, 2013.
One of the robot's hands was developed by 
Sandia National Laboratories, while the other
was developed by iRobot.
Atlas is built for performing simple tasks
such as shutting off valves, opening doors
and operating powered equipment in environments
where humans could not survive

5. Atlas is equipped with two vision systems, a laser rangefinder and stereo cameras, both controlled by an onboard computer.
Atlas’s both hands has “Fine Motor Skill” (Dexterity) capabilities.
Dexterity is the coordination of small muscle movements—usually involving the synchronization of hands and fingers—with the eyes. 
The complex levels of manual dexterity that humans exhibit can be attributed to and demonstrated in tasks controlled by the nervous system.
Fine motor skills aid in the growth of intelligence and develop continuously throughout the stages of human development.
Its limbs possess a total of 28 degrees of freedom. It can make simple and complex waves and moves in it’s arms, body like humans.
Atlas can navigate rough terrain and climb independently using its arms and legs, although the 2013 prototype version was tethered to an outside power supply to maintain stability.
In October 2013 Boston Dynamics uploaded a video showing Atlas could withstand being hit by projectiles and balance on one leg.

6. The United States Department of Defense stated in 2013 that it had no interest in using the robot for offensive or defensive warfare.
Google Acquired Boston Dynamics in December 2013.
Boston Dynamics is the most popular and advance Robotics company in the world.
Currently Atlas is the most advance 2 legs robot in the world. It can walk across rough terrain and even run on flat ground.

7. BigDog
BigDog is a dynamically stable quadruped robot created in 2005 by Boston Dynamics with Foster-Miller, the NASA Jet Propulsion Laboratory, and the Harvard University Concord Field Station.
Quadrupedalism or Pronograde posture is a form of terrestrial locomotion in animals using four limbs or legs.
An animal or machine that usually moves in a Quadrupedal manner is called Quadruped, meaning "four feet" (from the Latin quad for "four" and ped for "foot").
BigDog is 3 feet (0.91 m) long,
stands 2.5 feet (0.76 m) tall, and weighs
240 pounds (110 kg), about the size of a
small mule.
 It is capable of traversing difficult
terrain, running at 4 miles per hour (6.4
 km/h), carrying 340 pounds (150 kg)
and climbing a 35 degree incline.

8. Locomotion is controlled by an onboard computer that receives input from the robot's various sensors. Navigation and balance are also managed by the control system.
Instead of wheels or treads, BigDog uses four legs for movement, allowing it to move across surfaces that would defeat wheels. 
BigDog's walking pattern is controlled through four legs, each equipped with four low-friction hydraulic cylinder actuators that power the joints.
"The BigDog robot, labelled as a military robot mule, has subsequently proven its potential worth in its ability to reduce load and remove that burden from a soldier's back.“
The BigDog project was headed by Dr. Martin Buehler, who, in 2012, received the Joseph F. Engelberger Award from the Robotics Industries Association for the work.
Dr. Buehler, while previously a professor at McGill University, headed the robotics lab there, developing four-legged walking and running robots.
Built onto the actuators are sensors for joint position and force, and movement is ultimately controlled through an onboard computer which manages the sensors.

9. Approximately 50 sensors are located on BigDog.
These measure the attitude and acceleration of the body, motion and force of joint actuators as well as engine speed, temperature and hydraulic pressure inside the robot's internal engine.
Low-level control, such as position and force of the joints, and high-level control such as velocity and altitude during locomotion, are both controlled through the onboard computer.
On March 18, 2008, Boston Dynamics released video footage of a new generation of BigDog known as AlphaDog. The footage shows BigDog's ability to walk on icy terrain and recover its balance when kicked from the side.
The refined equivalent has been designed by Boston Dynamics to exceed the BigDog in terms of capabilities and use to dismounted soldiers.
