Biography

David Alatorre grew up in Mexico before moving to the UK to pursue higher education. He graduated from the University of Nottingham in 2015 with a first class MEng with honors in Mechanical Engineering with Mechatronics and began working towards his PhD in Robotics with the Rolls-Royce UTC in Manufacturing and On-Wing Technology. He is currently employed as a Research Fellow at the UTC working in the area of continuum robots for in-situ inspection and repair of industrial assets.

Current Research

Development of a continuum robot for remote applications as part of Innovate UK project COBRA, in partnership with Rolls-Royce, UKAEA RACE and OpTek Systems. COBRA aims to create a 5m long continuum robot for detailed inspection and laser ablation repairs of industrial assets such as gas turbines and nuclear reactors. The diameter of this continuum robot is limited by access constraints in aeroengines to 9mm, which presents a sizable challenge in miniaturisation and manufacture.

Past Research

  • Reconfigurable soft surfaces for composite manufacture: This project explored the use of pneumatically actuated soft surfaces to achieve a reusable and reconfigurable mold for fibre laying for composites manufacture. Vacuum jamming was used to stiffen the surface after continuum pneumatic muscles shaped the perimeter to the desired shape.
  • Position control of continuum robots using ionic liquid stretch sensors: This project explored the use of ionic liquids, electrically conductive liquid compounds, as high strain stretch sensors for serpentine continuum robots. Such sensors present a low-cost option for closed loop position control of soft robotics, a growing area of research worldwide.
  • Force control of in-situ machining robots using remote sensors: This project explored the use of remotely mounted microphones to listen to the sound of air-driven grinding tools during in-situ machining of aeroengine compressor blades. The indirect control of tool speed and hence torque using airborne sound signals proved to be an effective means of force control.
