In this episode, Audrow Nash interviews Elliott Rouse, Assistant Professor at the University of Michigan, about an open-source prosthetic leg—that is a robotic knee and ankle. Rouse’s goal is to provide an inexpensive and capable platform for researchers to use so that they can work on prostheses without developing their own hardware, which is both time-consuming and expensive. Rouse discusses the design of the leg, the software interface, and the project’s timeline.

In this interview, Audrow Nash interviews Helen Huang, Joint Professor at the University of North Carolina at Chapel Hill and North Carolina State, about a method of tuning powered lower limb prostheses. Huang explains how powered prostheses are adjusted for each patient and how she is using supervised and reinforcement learning to tune prosthesis. Huang also discusses why she is not using the energetic cost of transport as a metric and the challenge of people adapting to a device while it learns from them.

In this episode, Jack Rasiel interviews Vijay Kumar, Professor and Dean of Engineering at the University of Pennsylvania.  Kumar discusses the guiding ideas behind his research on micro unmanned aerial vehicles, gives his thoughts on the future of robotics in the lab and field, and speaks about setting realistic expectations for robotics technology.

A team led by Sunil Agrawal, professor of mechanical engineering and of rehabilitation and regenerative medicine at Columbia Engineering, has published a pilot study in Science Robotics that demonstrates a robotic training method that improves posture and walking in children with crouch gait by enhancing their muscle strength and coordination.

A newly developed vine-like robot can grow across long distances without moving its whole body. It could prove useful in search and rescue operations and medical applications.

Why are spiders’ webs so complex? Might they have other functionalities besides being a simple trap? One of the most interesting answers to this question is that spiders might use their webs as computational devices.

MIT CSAIL team’s system of quadcopters that fly and drive suggest another approach to developing flying cars

Harvard scientists use simple materials to create semi-soft machines that walk like insects.

The device named “Spark” flew high above the man on stage with his hands waving in the direction of the flying object. In a demonstration of DJI’s newest drone, the audience marveled at the Coke can-sized device’s most compelling feature: gesture controls. Instead of a traditional remote control, this flying selfie machine follows hand movements across the sky. Gestures are the most innate language of mammals, and including robots in our primal movements means we have reached a new milestone of co-existence.

A researcher at the University of the West of England (UWE Bristol) is developing a bio-inspired ‘smart’ knee joint for prosthetic lower limbs. Dr Appolinaire Etoundi, based at Bristol Robotics Laboratory, is leading the research and will analyse the functions, features and mechanisms of the human knee in order to translate this information into a new bio-inspired procedure for designing prosthetics.

Teen roboticist Ben Vagle returns with an updated version of his TrotBot—this time featuring retractile toes.

Robots and plants are being intricately linked into a new type of living technology that its creators believe could be used to grow a house.

In this episode, Audrow Nash interviews Bradley Knox, founder of bots_alive. Knox speaks about an add-on to a Hexbug, a six-legged robotic toy, that makes the bot behave more like a character. They discuss the novel way Knox uses machine learning to create a sense character. They also discuss the limitation of technology to emulate living creatures, and how the bots_alive robot was built within these limitations.

Chances are that you’ve never given much thought to how insects walk, or what combination of leg movements–or gaits–is most stable or fastest, but, if like a group of scientists from Ramdya, Floreano and Ijspeert labs, NCCR Robotics, you are trying to create fast and robust robots, taking inspiration some of nature’s most agile movers might give you just the inspiration you need.

Engineers at MIT have fabricated transparent, gel-based robots that move when water is pumped in and out of them. The bots can perform a number of fast, forceful tasks, including kicking a ball underwater, and grabbing and releasing a live fish.
