Most folks possible consider robots as advanced digital gadgets, made up of many elements that must be assembled in factories. An experimental new non-electronic bot, nonetheless, might be 3D-printed multi functional piece, and it is powered by nothing however air.
The soft-bodied robotic was created by postdoctoral scholar Yichen Zhai and colleagues, within the lab of Prof. Michael Tolley at UC San Diego’s Department of Mechanical and Aerospace Engineering.
It was 3D-printed in a single steady 58-hour step, composed of a single piece of sentimental and versatile thermoplastic polyurethane (TPU). Oh sure, and it has six legs. All of these appendages have 4 levels of freedom, that means they will transfer up and down plus ahead and backward.
The legs are moved not by electrical motors, however as an alternative by a gradual stream of compressed air. That air repeatedly flows from a pump or onboard CO2 canister, by means of an inner “pneumatic oscillating circuit,” and finally out of exhaust ports within the robotic’s physique.
As the air goes by means of the circuit, it sequentially triggers a sequence of TPU actuators which repeatedly transfer the legs as two units of three limbs. In this way, the robotic is ready to waddle its method throughout several types of terrain – it might even stroll underwater.

In its absolutely self-contained configuration, the bot’s runtime is proscribed by the capability of its CO2 canister. If hooked as much as an exterior pump, nonetheless, it ought to reportedly be capable of stroll for 3 days straight earlier than requiring any upkeep. And even when it does put on out after three days, roughly US$20 is all it takes to make a brand new one.
It is hoped that descendants of the robotic may sooner or later be used to discover settings the place electronics will not work or are impractical, reminiscent of in high-radiation environments or the floor of different planets. Future analysis will give attention to strategies of storing the CO2 inside the robotic, and on the usage of 100% biodegradable supplies.
“This is a totally totally different method of taking a look at constructing machines,” says Tolley.
A paper on the analysis was lately printed within the journal Advanced Science News. You can see the robotic in six-legged motion, within the video beneath.
