A Computational Model of Hybrid Trunk-like Robots for Synergy Formation in Anticipation of Physical Interaction

Biomimetics, Journal Year: 2025, Volume and Issue: 10(1), P. 21 - 21

Published: Jan. 2, 2025

Trunk-like robots have attracted a lot of attention in the community researchers interested general field bio-inspired soft robotics, because trunk-like arms may offer high dexterity and adaptability very similar to elephants potentially quite superior traditional articulated manipulators. In view practical applications, integration hydrostatic segment with hard-articulated segment, i.e., hybrid kinematic structure elephant’s body, is probably best design framework. It proposed that this should occur at conceptual/cognitive level before being implemented specific technologies, including related control paradigms. The modeling approach based on passive motion paradigm (PMP), originally conceived for addressing degrees freedom problem highly redundant, structures. shown can be naturally extended from redundant hyper-redundant structures, structures include hard component. PMP model force-based, not motion-based, it characterized by two main computational modules: Jacobian matrix chain compliance maps generalized force fields into coordinated gestures whole-body model. how modulation used synergy formation process, which coordinates nature body and, same time, preparation trunk tip stable physical interaction environment, agreement impedance–control concept.

Versatile graceful degradation framework for bio-inspired proprioception with redundant soft sensors

Frontiers in Robotics and AI, Journal Year: 2025, Volume and Issue: 11

Published: Jan. 6, 2025

Reliable proprioception and feedback from soft sensors are crucial for enabling robots to function intelligently in real-world environments. Nevertheless, fragile susceptible various damage sources such Some researchers have utilized redundant configuration, where healthy compensate instantaneously lost ones maintain accuracy. However, achieving consistently reliable under diverse sensor degradation remains a challenge. This paper proposes novel framework graceful systems, incorporating stochastic Long Short-Term Memory (LSTM) Time-Delay Feedforward Neural Network (TDFNN). The LSTM estimates readings compare them with actual data. Then, statistically abnormal zeroed out. TDFNN receives the processed perform proprioception. Simulation experiments musculoskeletal leg that contains 40 nonlinear demonstrate effectiveness of proposed framework. Results show knee angle accuracy is retained across four distinct scenarios. Notably, mean error increases by less than 1.91°(1.36%) when 30% degraded. These results suggest enhances reliability proprioception, thereby improving robustness applications.
