Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor ...

A Korean research team has developed a plastic-based nanogenerator that can power sensors and robots without battery replacement or charging. It can supply stable direct current (DC) power from ...

Retire your old mop and bucket. The best robot mops we've tested keep your floors squeaky clean with little effort on your part. I’m PCMag’s senior writer covering smart home and wearable devices.

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...

Abstract: This letter introduces two multi-sensor state estimation frameworks for quadruped robots, built on the Invariant Extended Kalman Filter (InEKF) and Invariant Smoother (IS). The proposed ...

Blind Spot Management System or BSMS is an IoT-based parking safety project built to help drivers and lot controllers detect blind spot risks in real time. Drivers often cannot see around sharp turns ...

Abstract: A dynamic weighted multi-sensor fusion method is proposed to address localization degradation in four-wheeled differential mobile robots under GNSS denial and wheel slippage conditions.
