Biography

Ali received his BSc from Tehran University, Iran, in Mechanical Engineering; and subsequently his MSc in Mechanical Engineering (Dynamics & Control) from the University of Arizona, U.S.A. His Masters thesis is about modelling switching networks using Bond Graphs.
Since October 2014, Ali has been working as a PhD student at the Centre of Robotics Research (CoRe) at King’s College London under the supervision of Dr. Thrish Nanayakkara and Prof. Kaspar Althoefer. His main areas of interest are Dynamics, Multi Body Dynamics, and Control. Ali is currently working on active stiffness control of a pneumatically actuated soft continuum manipulator based on the STIFF FLOP project, entailing modelling, simulation and control of this manipulator. In addition, he is part of the King’s College team on the EU project named FourbyThree  which looks into safe human-robot interaction in industrial settings.

Involvement in Projects during PhD Research

  1. STIFF FLOP Project – EU: STIFF-FLOP  focuses on Challenge 2 – Cognitive systems and robotics. In minimally invasive surgery, tools go through narrow openings and manipulate soft organs that can move, deform, or change stiffness.

STIFF FLOP manipulator is being pressurised, and external force is being applied at the tip by human interaction and measured by the ATI Nano17 force sensor to generate a map between external excitation and change of parameters such as position and internal pressure.

 2. FourByThree Project – EU Horizon2020: This projects looks into the development of a new generation of modular industrial robotic solutions that are suitable for efficient task execution in collaboration with humans in a safe way and are easy to use and program by the factory workers.

Demonstrating Active Stiffness Adjustment in The Baxter Arm Utilising Fuzzy Inference Based on Human/Robot Relative Position/Velocity.
