- •
A model was developed to predict capsule endoscope (CE) frictional resistance.
- •
Drag tests, varying CEs, and tissue parameters were used to validate the model.
- •
The model was validated using excised porcine intestinal tissue from all regions.
- •
Of all parameters studied, edge radius influenced frictional resistance the most.
- •
The model and experimental results exhibited an average error of 6.25%.
