AI in practice: 4 real uses of AI described

What this episode covers

Dr. Thomas Thuruthel of the University of Cambridge explains how machine learning models control soft robotic grippers and describes self-healing elastomers with dynamic cross-links for disaster and medical applications. Angus Clark from Imperial College London discusses malleable robotics, using variable stiffness links like Mylar to combine the strength of rigid robots with the compliance of soft ones for industrial collaboration. Dr. Jelizaveta Konstantinova of Ocado Technology details how soft robotics and AI-driven suction systems handle diverse grocery items, leveraging acquisitions of Kindred Systems and Paddington Dynamics to scale automation.

AI in practice

Where this conversation describes AI being used to build or deliver a product. Part of the AI in practice tracker.

Engineering & simulation

Machine learning was used to develop control models for soft robots by mapping inputs to deformations, allowing the system to predict how the robot body would behave when actuated without relying on complex, inaccurate physics-based mathematical models.

“So that's why machine learning was kind of good for these kind of robots. So you are actually able to develop models faster. So models certainly means like you need to have an idea about what will happen to your body once I actuate it.”

Engineering & simulation

A neural network was trained using camera data to learn the mapping between input signals and physical deformations, which was then used to develop controllers for gripping objects with soft robotic fingers.

“So you look at use cameras to see what how it actually deforms. Collect a lot of data. So that's the key in nation learning. You collect a lot of data to show this is how it should deform, and then tell a new network to kind of find the mapping between this input and this deformations.”

Manufacturingpick speed doubled from 6 months ago

Ocado Technology implemented a robotic picking system using machine learning and computer vision to achieve successful grips on diverse grocery items without prior knowledge of the object, enabling faster picking speeds.

“One way in which Akado technology has approached this problem. is through the development of an advanced robotic picking system, it uses a suction cup. This system utilizing that cutting age machine learning in computer vision technologies that enable to achieve as a successful grip.”

Engineering & simulationdeep reinforcement learning

Acquired company Kindred Systems utilized deep reinforcement learning and machine vision systems to develop state-of-the-art robotic manipulation technology for autonomous systems operating at scale.

“So, kindred has state of the art robotic manipulation technology with advanced capabilities of deep reinforcement learning, machine vision systems, gripper technologies, celebration, supervised autonomy, to operate autonomous systems at scale.”

    228. Harvard’s Soft Robot Gives Movement Back to ALS & Stroke Patients

    The hosts discuss a wearable soft robotic sling developed by Harvard’s Walsh Biodesign Lab to assist ALS and stroke patients with shoulder and arm mobility. The device uses a personalized intention detector model and a hysteresis physics model to provide just enough pneumatic support for natural movement, avoiding the over-assistance of previous rigid exoskeletons. Patient Kate Nicks, who has ALS, reported regaining the ability to perform daily tasks like combing her hair using her dominant right arm after years of relying on her left.
