Meet Cassie – The Guinness world record holding robot

Let us introduce you to Cassie, who is a Guinness World Record holder (check out here) for the fastest 100 meters by a bipedal robot. Cassie clocked the historic time of 24.73 seconds at OSU’s Whyte Track and Field Center, starting from a standing position and returning to that position after the sprint, with no falls.

Robot Name: Cassie

Company / Institute: Agility Robotics

Location: Oregon, USA

Inception: 2017

Sensors: IMUs, force sensors, joint position encoders, and LiDAR

Skills: Dynamic walking, balancing, navigation on uneven terrain, stair climbing

Industry: Logistics, Research, and Development

Programming Languages: Python and C++

Commercial availability: Yes, it is commercially available.

Cassie was invented at Oregon State University’s Dynamic Robotics Lab, under the leadership of Agility CTO Jonathan Hurst, and was Agility’s first commercial robot.

Cassie, a groundbreaking bipedal robot by Agility Robotics, revolutionizes the world of legged robots with its robust design and adaptability. Introduced in 2017, Cassie combines advanced mobility with precise engineering, making it an ideal platform for research, development, and various commercial applications. Its unique ability to balance dynamically and traverse challenging terrains mimics the gait of humans, setting it apart from traditional wheeled or tracked robots.

Cassie can walk forward, backward as well as sideways like we humans can do, in fact, somewhat better than us. During the testing and experimenting phase, Cassie has gone through a lot and lot of practice and after all these efforts, it was able to achieve the honor of a record holding robot. In the video links shared at the bottom of this blog, it can be seen how Cassie has been working hard to achieve it’s aim. (Obviously, it is the team at Agility Robotics that is working hard, not Cassie itself :-))

Cassie does not only hold a record of fastest 100 meter by a bipedal robot. It is also the first bipedal robot to use machine learning to control a running gait on outdoor terrain, completed the 5 kms on Oregon state’s campus untethered and on a single battery charge.

Technology:

Cassie leverages cutting-edge actuator technology and advanced control algorithms to replicate the natural movement of human legs. The robot’s onboard sensors, including IMUs and force sensors, provide real-time feedback for balance and navigation, ensuring agility and adaptability in complex environments.

Programming Languages:

Cassie’s software is primarily built using Python and C++, combining Python’s ease of scripting for high-level control with C++’s efficiency for real-time computations. This dual-language approach allows developers to prototype quickly while maintaining optimal performance.

Current use:

Cassie is utilized in academic research institutions for studying legged locomotion, as well as in logistics and delivery trials by companies exploring next-generation automation solutions.
