Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

open access: yesAdvanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Boxplot of mean-adjusted number of detections per hour during four light regimes, averaged over available years of data for each station and over seasons of Antarctic blue whale presence of the corresponding station (autumn, winter and spring for MAD, NEAMS, SSEIR and SWAMS; the entire year for NCRO and WKER).

open access: yes, 2016
Lower and upper bounds of boxes represent lower and upper quartiles, respectively. Red lines are median values and asterisks are mean values. Note that means (asterisks) sometimes differ from median due to many outliers, not shown in the graphic for more

Multidirectional Motion Strategy of Miniature Water Surface Robot Actuated by Single Exciter

open access: yesAdvanced Robotics Research, EarlyView.
A novel multidirectional motion strategy on the water surface based on a single exciter is proposed, and a single‐exciter single‐plate module is developed for actuation. The driving forces generation mechanism of the module is revealed from the perspective of the asymmetric surface wave field.
