Ultrasound beam propulsion, a propulsion system that uses airborne ultrasound phased arrays (AUPAs) to propel a blimp in an indoor environment to propel a blimp, has advantages for operations near humans such as no audible noises and no risk of propeller strike. To achieve the high mobility with lim…
Human–robot interaction (HRI) has been widely researched in diverse applications. A robot following a person is one such scenario investigated in the HRI field. However, human movements and actions are complex and can change dramatically. We herein demonstrate a machine learning-based system that al…
In this letter, we demonstrate a new robotic framework where a lightweight balloon with no onboard actuators or batteries acts as a mid-air robot that travels three-dimensionally within a workspace. The workspace contains five sparsely arranged ultrasound transducer arrays emitting steerable plane w
