WTF Fun Fact 13622 – 3D Printed Robotic Hand

A significant leap in 3D printing has emerged from ETH Zurich and a U.S. startup. They’ve created a robotic hand that mimics human bones, ligaments, and tendons. Unlike traditional methods, this innovation uses slow-curing polymers. These materials offer improved elasticity and durability.

Led by Thomas Buchner and Robert Katzschmann, the project utilized thiolene polymers. These materials quickly return to their original form after bending. Hence, they are perfect for simulating a robotic hand’s elastic components. This choice represents a shift from fast-curing plastics, expanding the possibilities in robotics.

Soft Robotics for a Robotic Hand

Soft robotics, illustrated by this 3D-printed hand, brings several advantages. These robots are safer around humans and more capable of handling delicate items. Such advancements pave the way for new applications in medicine and manufacturing.

The project introduced a novel 3D laser scanning technique. It accurately detects surface irregularities layer by layer. This method is essential for using slow-curing polymers effectively in 3D printing.

ETH Zurich researchers collaborated with Inkbit, an MIT spin-off, for this venture. They are now exploring more complex structures and applications. Meanwhile, Inkbit plans to commercialize this new printing technology.

This breakthrough is more than a technical achievement. It marks a shift in robotic engineering, blending advanced materials with innovative printing techniques. Such developments could lead to safer, more efficient, and adaptable robotic systems.

Educational and Practical Benefits

The success in printing a lifelike robotic hand has implications for both education and industry. It bridges the gap between theory and practice, potentially revolutionizing robotics in various settings.

The ability to print intricate robotic structures in a single process opens doors to futuristic applications. Robots could become more common in households and industries, enhancing efficiency and convenience.

This milestone in robotic engineering demonstrates the power of innovation and collaboration. As we enter a new chapter in robotics, the possibilities for applying this technology are vast and exciting.

WTF Fun Fact 13484 – Robots That Feel

Robots that feel?! Ok, no. We don’t mean robots that have feelings. We mean robots that have a “sense” of touch. Or at the very least robots programmed not to crush things they pick up. That’s still progress!

The modern robotics field is continuously pushing the boundaries of technology and automation. As a part of this ongoing exploration, scientists from the Queen Mary University of London, alongside their international colleagues from China and USA, have developed an innovative, affordable sensor called the L3 F-TOUCH. This unique invention enhances a robot’s tactile abilities, granting it a human-like sense of touch.

Robots That Feel Thanks to the L3 F-TOUCH Sensor

A principal objective in robotics has been achieving human-level dexterity, specifically during manipulation and grasping tasks. The human hand’s ability to sense factors such as pressure, temperature, texture, and pain, in addition to distinguishing objects based on properties like shape, size, and weight, has set the standard.

Until now, many robot hands or graspers have fallen short, lacking these vital haptic capabilities. As you might imagine, this makes handling objects a complicated task. Robots’ fingers lack the “feel of touch,” resulting in objects slipping away or being unintentionally crushed if fragile. And that’s not something we want if we’re ever going to let them work with people, like the elderly.

Mechanics and Functionality

Leading the groundbreaking study, Professor Kaspar Althoefer of Queen Mary University of London and his team, introduces the L3 F-TOUCH. The name stands for Lightweight, Low-cost, and wireless communication. It’s a high-resolution fingertip sensor that directly measures an object’s geometry and the forces necessary to interact with it.

This sensor sets itself apart from others in its league that estimate interaction forces via camera-acquired tactile information. The L3 F-TOUCH takes a direct approach, achieving a higher measurement accuracy.

Professor Althoefer and his team plan to further enhance the sensor’s capabilities. They aim to add rotational forces such as twists, vital in tasks like screw fastening.

These advancements could extend the sense of touch to more dynamic and agile robots, improving their functionality in manipulation tasks and even in human-robot interaction settings, such as patient rehabilitation or physical support for the elderly.

WTF Fun Fact 13405 – Robot Pizza Maker

A robot pizza delivery startup that raised nearly half a billion dollars has closed due to technological setbacks. The company, Zume, Inc., had been working on developing a mobile pizza-making machine for years.

There’s big money in future pizza

The failure is surprising, considering the substantial amount of investment capital it received. But this helps highlight the ongoing challenges faced by practical robotics ventures.

One of the key hurdles faced by the robot pizza startup was the difficulty of building a reliable mechanical pizzaiolo. The company struggled for years to prevent melting cheese from sliding off the pizzas while they were being baked in their moving trucks. But this posed too significant of an obstacle. The cheese won.

Does robot pizza have a future?

Interestingly, the robot pizza industry is larger than one might assume. There are several Silicon Valley companies working on automating the pizza-making process. For instance, Stellar Pizza, founded by former SpaceX engineers, is developing a robot capable of making dough, rolling it out, applying various toppings, and baking the pizza.

However, the ambitions of these companies are not focused on recreating the experience of a traditional Italian pizza fresh out of the oven. Instead, they aim to compete with established pizza chains like Domino’s, targeting a more mass-market audience.

Cheesy obstacles

The shutdown of Zume Inc. serves as a cautionary tale in the world of venture investing – and of pizza. Even with significant funding and promising technological ideas, execution and overcoming practical challenges remain critical. This robot pizza startup emphasizes the challenges of trying to merge robotics and culinary endeavors and the difficulties inherent in translating innovative concepts into viable and successful businesses.

Zume Inc. has reportedly engaged the services of Sherwood Partners, a restructuring firm, to facilitate the sale of its assets. The company’s decision to wind down its operations reflects the reality of its financial situation and the inability to sustain its business model in a competitive market.

In the meantime, we’ll just have to appreciate the world’s pizza-makers even more. At least they can keep the cheese in place!
