Dual arm master controller development [PDF]
, 1985 The advanced servomanipulator (ASM) slave was designed with an anthropomorphic stance gear/torque tube power drives, and modular construction. These features resulted in increased inertia, friction, and backlash relative to tape driven manipulators ...

Crater Observing Bioinspired Rolling Articulator (COBRA)
Advanced Intelligent Systems, EarlyView.Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

BeeRootBot: A Bioinspired Robotic Probe Exhibiting Apical Growth through In Situ Soil Binding
Advanced Intelligent Systems, EarlyView.This study introduces a novel method for consolidating subterranean exploration pathways in plant‐inspired robots by binding in‐situ soil with beeswax, a biobased material. This simultaneous advancement and wall‐lining process reduces penetration resistance, enhances exploration efficiency, enables communication and resource sharing, and promotes ...

British Educational Research Journal, EarlyView.Abstract The latest reform of initial teacher education (ITE) in France, introduced in 2021, aims to make teacher training less theoretical and therefore more ‘practical’. New elements, such as the replacement of the Écoles Supérieures pour le Professorat et l'Éducation (ÉSPÉs) by the Instituts Nationaux Supérieurs du Professorat et de l'Education ...
