Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review
Advanced Intelligent Systems, EarlyView.This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.

Topology Optimization for a Rigid‐Compliant Hybrid Constant Force Gripper
Advanced Intelligent Systems, EarlyView.Constant‐force grippers deliver near‐constant output without sensors, cutting cost and complexity. This study proposes a topology‐optimization framework jointly designing rigid links and material distribution, modeled via link‐state and element‐density variables with constant force as the objective.
