Design of a soft robotic endoscope with enhanced bending and Al-based prediction
Minimally invasive surgery (MIS) demands advanced soft robotic endoscopes that offer superior maneuverability and patient safety, especially at low actuation pressures. This analysis explores a novel soft robotic endoscope design that achieves significantly higher bending angles at reduced pressure, validated through Finite Element Analysis (FEA) and an AI-driven prediction model. Our findings demonstrate a breakthrough in endoscope performance and design efficiency, paving the way for safer, more precise surgical interventions.

The proposed endoscope features a novel cylindrical design with 5 circumferentially spaced semicircular chambers, optimized for asymmetric bending and reduced radial expansion. Constructed from Ecoflex 00-50 silicone and covered with a fiber outer sheath, it ensures high flexibility, structural stability, and efficient actuation, achieving a 90° bending angle at a remarkably low 0.2 bar pressure.
Finite Element Analysis (FEA) using ANSYS Workbench confirmed the design's structural performance under pneumatic actuation. A Yeoh hyperelastic material model (C10 = 0.045 MPa, C20 = 0.01 MPa) accurately simulated the large, nonlinear deformations typical in soft silicone. FEA proved the design's ability to achieve significant bending while maintaining integrity, evaluating performance across various pressure conditions and chamber activations.
An Artificial Intelligence (AI) model, developed using Artificial Neural Networks (ANN) and Support Vector Machines (SVM), accurately predicts bending and twisting angles, and speeds. Trained on a 500-sample dataset from Python simulations, the ANN achieved an R² score of 0.85 for bending angle prediction, significantly reducing the need for extensive physical prototyping and accelerating design optimization.
Physical fabrication using FDM 3D printing for molds and Ecoflex 00-50 casting validated the design. Experimental tests confirmed the high bending angles at low pressures (e.g., 57.8° at 15 kPa) with excellent repeatability (Std Dev 1.22°). Minor deviations between simulation and experiment were attributed to material nonlinearities and manufacturing tolerances, yet overall, the experiments validated the accuracy of both FEA and AI models.

AI-Powered Precision: Predicting Endoscope Deformation
The developed AI model, utilizing Artificial Neural Networks (ANN) and Support Vector Machines (SVM), accurately predicts key deformation parameters. For bending angle, the ANN achieved an R² score of 0.85 with an RMSE of 15.18°, demonstrating its capability to capture complex, nonlinear relationships across various pressure conditions and chamber activations.
This predictive power drastically reduces the need for costly and time-consuming physical prototypes, accelerating design iterations and time-to-market while enhancing the safety and control of surgical procedures.
