KellyOnTech What are the lastest developments in soft robotics

In this episode, let’s talk about the latest developments in soft robotics.

According to Wikipedia, “Soft robotics is a specific subfield of robotics that involves building robots from highly compliant materials, similar to those found in living organisms.”Soft robots borrow heavily from the way living organisms move and adapt to their surroundings. Compared with robots made of rigid materials, soft robots can improve the flexibility and adaptability of tasks and improve safety when working around humans. These properties make it potentially useful in medicine and manufacturing. “

How big is the market for soft robots?

According to an analysis by Research and Markets, the global soft robotics market was valued at USD 645 million in 2019 and is expected to reach USD 4.965 billion by 2025, growing at a CAGR of 40.5% during the forecast period 2020–2025.

What is the world’s first fully independent soft robot?

“Octobot” is the world’s first completely independent soft robot, small enough to fit in the palm of your hand, developed by Harvard University in 2016. It has no hard electronics — no batteries or computer chips — and can move without being tethered to a computer. It is driven by chemical reactions and is controlled by microfluidic logic that directs the flow of fuel.

Octobot is basically a pneumatic tube, how does it move? Harvard researchers pumped a high concentration of hydrogen peroxide into the Octobot’s body. The pressure pushes the liquid through a tube in the body, eventually to a platinum wire, where a catalytic reaction occurs and the gas expands and travels through a tiny microfluidic controller. Alternate releases of gas caused the soft robot to swing its tentacles up and down, moving around in the process. One millilitre of fuel can move the Octobot for about eight minutes.

How to build such a soft robot?

Harvard researchers tried more than 300 times to find the right formula. First, they placed the microfluidic chip into an empty, custom-made octopus mold. They then poured a silicone mixture into the mold to cover the chip. After the ink lines were then injected into the silicone using a 3D printer, they needed to be baked for four days to allow one of the inks to evaporate, leaving a hollow container through which pressurized gas could flow.

Although not equipped with sensors and programming capabilities (no better control over the robot’s movements), the invention of the Octobot means that soft robots are completely achievable.

What exactly are the applications of Soft Robotics?

Here I introduce a startup called Soft Robotics, founded in Boston in 2013. The company focuses on developing soft robotics for automated sorting in food processing and logistics distribution, and covers more than 40 patents and applications, including know-how in actuator geometry, material selection and operating range. Soft Robotics develops soft robots that are highly adaptable while reducing system complexity and overall system cost. Fully automatic it can pack a tote bag, pick fruit from a vine, or easily handle a 10-pound kettlebell.

In 2019 Soft Robotics launched mGrip, the company’s first on-demand modular automation system that allows users to quickly build, validate and install production systems based on the company’s needs, greatly contributing to the popularity of soft robotics.
