The robot can drive on various surfaces such as concrete or packed soil and carry up to three times its own weight.
The robot can drive on surfaces such as concrete or packed soil and carry up to three times its weight in equipment such as a camera or sensors. It uses a light sensor to move automatically toward light sources, which enables it to run indefinitely on harvested power.at the ACM MobiCom 2023 conference in Madrid, Spain, on October 2.
The team drew inspiration from "intermittent computing," a concept that divides intricate programs into small tasks. This approach enables a device with extremely constrained power resources to operate gradually, taking advantage of available energy as it becomes accessible. They applied this idea to motion and reduced the robot's size and weight, so moving takes only a small amount of energy.
The researchers have equipped MilliMobile with light, temperature, and humidity sensors and Bluetooth, allowing them to transmit data over 200 meters. They plan to add more sensors and improve data-sharing among swarms of these robots in the future. Various awards and fellowships from Amazon, Google, the National Science Foundation, the National GEM Consortium, the Washington NASA Space Grant Consortium, the Pastry-Powered uring Machine Endowed Fellowship, and the SPEEA ACE fellowship program funded this research.

Researchers propose 3D printing of high-performance elastomers through vat photopolymerizationAcrylate-based ultraviolet (UV)-curable resins are currently used as raw materials to obtain desired performance by adjusting the types and ratios of oligomer and reactive monomers in the resin system. However, due to low degree of free-radical polymerization, the elastomers prepared by vat photopolymerization (VPP) technology show low strength, poor resilience, and unsatisfactory mechanical properties.
