How to Design Your Artificial Muscle Actuator?

Marwa ElDiwiny

In this research paper, a white model is proposed for explaining and answering the observed physical phenomena occurs during the experimental work. Basically in this model, we focus on the electrostatic force generated among electrons and mobile ion while it is in air configuration. The prime point in this model is computing the stress induced by mobile ions on the electronic conducting polymer surface, equations are used for estimating the stress, while F is the coulomb force of attraction and repulsion forces. Through the model we are capable of answering these following research questions: How is the relation between the mobile ion radius and the elementary electric charge radius for generating the force?; What are the conditions of generating force: the number of the interacting elementary electric charges and mobile ions?; Why the generated force saturates in the electronic conduct- ing polymer?; What is the correlation between number ofions in the ECP and geometry variation?. To which extent do clamping unit affect in the ECP performance.

Simulating, Fabricating and Controlling a PneuNets-Gripper

Eulalie Coevoet, Damien Marchal, Olivier Goury, and Marwa ElDiwiny

This tutorial is about designing, simulating and fabricating a soft gripper made with PneuNets actuators in Sofa-SR. Sofa-SR is a modeling, simulation and control environment for soft robotics using the simulation framework Sofa for rigid and deformable mechanics, and the plugin SoftRobots. PneuNets (pneumatic networks) are a class of soft actuator originally developed by the Whitesides Research Group at Harvard. They are made up of a series of channels and chambers inside an elastomer. These channels inflate when pressurized, creating motion. With three of such actuators it is possible to make a soft gripper.

Atomistic Modelling and Simulation of Ionic Conducting Polymer

Tarmo Tamm, Marwa ElDiwiny

In this project we working on atomistic modelling of ionic electro active polymer to derive the deriving force field formula.

Soft Robotics Podcast


Bio-inspired Soft Robots for Healthcare, with Yong-Lae Park

In this episode, Yong-Lae Park is interviewed, Associate Professor at Seoul National University in South Korea, about the bio-inspired design and manufacture of soft robots and microrobots for healthcare. Park’s research goal is to analyze the design and dynamics of biological systems and transform them into robotic/mechatronic systems for human life. Some of the his projects include development of artificial skin sensors, soft Muscle Actuators, and wearable robots for human rehabilitation.


Towards using Micro and Nano Robots in the Human Body, with Peer Fischer

In this episode, Peer Fisher is interviewed, a Professor of Physical Chemistry at the University of Stuttgart and the Director of the Micro Nano and Molecular Systems Lab at the Max Planck Institute for Intelligent Systems. Fischer discusses micro robots that has been designed to move inside of environments similar to the human body called, “micro swimmers.” He talks about how they are fabricated, powered, and how they can move with light or “nano propellers.” Fischer also discusses simulating human tissue and the future of micro and nano robots, including how they could be a replacement for certain surgeries.
