'This technology will simply explode at some point, when we create vehicles so automated and robots so efficient that deliveries and shipments are nearly free, ' said Jonathan Hurst, an associate professor of robotics in the Oregon State University (OSU) College of Engineering, chief technology officer at Agility Robotics and an global leader in the development of legged locomotion.

Although the machine is meant to be a development platform, Researchers foresee its design being used to develop robots that deliver packages or assist in search and rescue missions.

"Quite simply, robots with legs can go a lot of places that wheels cannot". This will be the key to deliveries that can be made 24 hours a day, 365 days a year, by a fleet of autonomous vans that pull up to your curb, and an on-board robot that delivers to your doorstep. In the long term, the revolutionized robot mobility could be used for delivering goods and also to perform search and rescue missions that are too risky for humans to venture.

It can also steer itself and "take a pretty good fall without breaking". The product efficiently brings automated logistics from the warehouses out and into the world.

However, this vision is long-term and will need many steps along the way. "This allows the motor to be smaller and the robot to be far more efficient than even ATRIAS was". Agility Robotics scientists noted that other bipedal robots should not be compared with Cassie when it comes to dynamically walking around because Cassie exceeded any other robot's performance.

Robot makers have turned to nature for their latest creation - a two-legged machine that walks like an ostrich.

'With Cassie, we've fixed this problem and added steering, feet, and a sealed system, so it will work outdoors in the rain and snow as we continue with our controller testing'.

Though the new two-legged robot dubbed Cassie is meant to walk like a human, its crouched legs look more like that of an ostrich.

"We weren't trying to duplicate the appearance of an animal, just the techniques it uses to be agile, efficient and robust in its movement", Jonathan Hurst, an associate professor of robotics in the OSU College of Engineering, said in a statement. Some may say that this robot is creepy, walking just like a chicken. Hiring is anticipated for research, production and development. That may help Cassie - or whatever Agility's next generation is called - remain in the package delivery race until retail and delivery companies are ready for them. Replicating those senses in a machine and then getting them to work together seamlessly is far from easy.
