Grip as Needed, Glide on Demand: Ultrasonic Lubrication for Robotic Locomotion
Mostafa A. Atalla, Daan van Bemmel, Jack Cummings +3
Friction is the essential mediator of terrestrial locomotion, yet in robotic systems it is almost always treated as a passive property fixed by surface materials and conditions. He…
OSCAR: An Ovipositor-Inspired Self-Propelling Capsule Robot for Colonoscopy
Mostafa A. Atalla, Anand S. Sekar, Remi van Starkenburg +4
Self-propelling robotic capsules eliminate shaft looping of conventional colonoscopy, reducing patient discomfort. However, reliably moving within the slippery, viscoelastic enviro…
Active Lubrication of Transluminal Medical Instruments
Mostafa A. Atalla, Jelte Nieuwenhuis, Alan Martin +6
Transluminal minimally invasive surgery uses natural orifices and small incisions to access internal anatomical structures, promoting quicker recovery and reduced morbidity. Howeve…
3D Printable Gradient Lattice Design for Multi-Stiffness Robotic Fingers
Siebe J. Schouten, Tomas Steenman, Rens File +5
Human fingers achieve exceptional dexterity and adaptability by combining structures with varying stiffness levels, from soft tissues (low) to tendons and cartilage (medium) to bon…
