Topological Analog Signal Processing

Topological Analog Signal Processing

Researchers at the Swiss Federal Institute of Technology in Lausanne (EPFL) used a Speedgoat Performance real-time target machine and a high-speed analog IO131 module to validate an acoustic topological equation solver experimentally. The setup allowed them to demonstrate the robustness of analog signal processors (ASP) and is an essential step towards a new generation of ultrafast all-optical ASPs.

Robust Switching Control Method to Achieve Tokamak-Shaped Plasma

Robust Switching Control Method to Achieve Tokamak-Shaped Plasma

A robust switching control method with state vector matching and a novel approach for the feedback system simulation are presented in this paper. First, the plant model reconstructs plasma equilibria from experimental data and calculates plasma shape changes. Then, the control system is discretized and run on a high-speed computer for experiments on a real-time testbed.

An Ankle-Foot Prosthesis Emulator Capable of Modulating Center of Pressure

An Ankle-Foot Prosthesis Emulator Capable of Modulating Center of Pressure

The authors of this paper developed an ankle-foot prosthesis emulator to restore human feet' balancing and push-off characteristics. The proposed emulator system consists of two torque-controlled forefoot digits and a torque-controlled heel digit which meets all design criteria to modulate the center of pressure and ground reaction force effectively.

Design and Experimental Characterization of a Hydrostatic Transmission for Upper Limb Exoskeletons

Design and Experimental Characterization of a Hydrostatic Transmission for Upper Limb Exoskeletons

The authors introduce a design of a novel hydrostatic air-liquid torque transmission system for an upper limb exoskeleton. Transmission of fluid on rolling membrane cylinders guarantees leakage-free operation, no backlash, and zero stick friction. By employing a new test bench of the fluid transmission system developed, they conducted experiments to characterize the static and dynamic response for different design parameters.

A Lightweight Force-Controllable Wearable Arm Based on Magnetorheological-Hydrostatic Actuators

A Lightweight Force-Controllable Wearable Arm Based on Magnetorheological-Hydrostatic Actuators

This paper studies the feasibility of using magnetorheological (MR) clutches coupled to a low-friction hydrostatic transmission.  This combination provides a highly effective yet lightweight, force-controllable supernumerary robotic arm (SRL). Experimental studies conducted on a one-DOF test bench and validated analytically demonstrate a high force bandwidth (>25 Hz) and an excellent ability to control interaction forces even when interacting with an external impedance.
