The ability to move backward is crucial for millimeter-scale microrobots navigate dead-end tunnels that are too narrow allow turning maneuvers. In this study, we introduce a 15-mm-long legged microrobot, BHMbot-B, which capable of rapid forward and locomotion through vibration mode transition control. By properly arranging the vibratory motions magnet, cantilever, linkages, pitching movement body forelegs in phase during first-order cantilever antiphase second-order mode, induces microrobot. Owing its outstanding load-bearing capacity, BHMbot-B equipped with dual electromagnetic actuators, an onboard battery, control circuit, can execute complex running trajectories under wireless command. Its maximum untethered speeds evaluated as 18.0 BL/s (360 mm/s) direction 16.9 (338 direction.

Abstract Leech locomotion, characterized by alternating sucker attachment and body contraction provides high adaptability stability on complex terrains. Herein, a leech‐inspired triboelectric soft robot is proposed for the first time, capable of amphibious movement, climbing, load‐carrying crawling. A high‐performance bionic system developed to drive control electro‐responsive robots. Its core components include: i) (LSR) made from segmented dielectric elastomer muscles. ii) The produces anisotropic frictional forces. iii) multi‐channel high‐voltage output nanogenerator (HDC‐TENG) effectively drives LSR. iv) unit adapted HDC‐TENG enables flexible LSR control. Using scalable structure muscles achieve maximum crawling speed 0.39 lengths per minute land (45 mm min −1 ) 0.22 in liquid (30.5 ). It can also carry payload 11.55 grams acrylic while This research sustainable promising new solution self‐powered energy sources suitable

Robots with adaptive morphology can improve interactions their environment, allowing functions without complicated control strategies. Inspired by a pufferfish, this paper introduces PufferFace Robot (PFR), vibration-propelled soft robot an design for exploring cavities using simple locomotion PFR is particularly useful inspecting centimeter-scale pipeline systems varying diameters and shapes, which pose substantial challenges. Although recent robots smart materials offer advantages, difficulties remain in handling different pipe sizes, navigating transitions, managing fluid flow. PFR's inflatable skin equipped flexible spikes that create asymmetrical friction under vibrations, propelling the forward feedback control. Its hollow structure allows flow, while front-mounted camera enhances inspection capabilities. adapts to various conditions, 1 1.5 times its diameter critical areas such as 90° elbows, T-connectors, high-curvature sections. In specific scenarios, generate propulsive force 20 35 weight.
