    • Assistance magnitude versus metabolic cost reductions for a tethered multiarticular soft exosuit 

      Quinlivan, Brendan Thomas; Lee, S.; Malcolm, Philippe; Rossi, D. M.; Grimmer, M.; Siviy, Christopher James; Karavas, Nikolaos; Wagner, D.; Asbeck, A.; Galiana, Ignacio; Walsh, Conor J (American Association for the Advancement of Science (AAAS), 2017)
      When defining requirements for any wearable robot for walking assistance it is paramount to maximize the user’s net metabolic benefit, while limiting the metabolic penalty of carrying the system’s mass. Thus, the aim of ...

    • Assured Safety Drill With Bi-Stable Bit Retraction Mechanism 

      Loschak, Paul; Xiao, Kechao; Pei, Hao; Kesner, Samuel Benjamin; Thomas, Ajith; Walsh, Conor (ASME, 2013-08-04)
      A handheld, portable cranial drilling tool for safely creating holes in the skull without damaging brain tissue is presented. Such a device is essential for neurosurgeons and mid-level practitioners treating patients with ...

    • A biologically-inspired multi-joint soft exosuit that can reduce the energy cost of loaded walking 

      Panizzolo, Fausto; Galiana, Ignacio; Asbeck, Alan; Siviy, Christopher James; Schmidt, Kai; Walsh, Conor J (Springer Nature, 2016)
      Background: Carrying load alters normal walking, imposes additional stress to the musculoskeletal system, and results in an increase in energy consumption and a consequent earlier onset of fatigue. This phenomenon is largely ...

    • Classroom to Clinic: Merging Education and Research to Efficiently Prototype Medical Devices 

      Hanumara, Nevan C.; Begg, Nikolai D.; Walsh, Conor; Custer, David; Gupta, Rajiv; Osborn, Lynn R.; Slocum, Alexander H. (IEEE, 2013)
      Innovation in patient care requires both clinical and technical skills, and this paper presents the methods and outcomes of a nine-year, clinical-academic collaboration to develop and evaluate new medical device technologies, ...

    • Design and control of a parallel linkage wrist for robotic microsurgery 

      Degirmenci, Alperen; Hammond, Frank L.; Gafford, Joshua Ball; Walsh, Conor J; Wood, Robert J.; Howe, Robert D. (2015)
      This paper presents the design and control of a teleoperated robotic system for dexterous micromanipulation tasks at the meso-scale, specifically open microsurgery. Robotic open microsurgery is an unexplored yet potentially ...

    • Design of Hybrid Passive and Active Mechanisms for Control of Insect-Scale Flapping-Wing Robots 

      Teoh, Zhi Ern (2015-09-20)
      Flying insects exhibit a remarkable ability to fly in environments that are small, cluttered and highly dynamic. Inspired by these animals, scientist have made great strides in understanding the aerodynamic mechanisms ...

    • Effect of timing of hip extension assistance during loaded walking with a soft exosuit 

      Ding, Ye; Panizzolo, Fausto A.; Siviy, Christopher; Malcolm, Philippe; Galiana, Ignacio; Holt, Kenneth G.; Walsh, Conor J. (BioMed Central, 2016)
      Background: Recent advances in wearable robotic devices have demonstrated the ability to reduce the metabolic cost of walking by assisting the ankle joint. To achieve greater gains in the future it will be important to ...

    • A Multi-faceted Approach to Cardiac Repair 

      Roche, Ellen Tunney (2015-05-14)
      Treatment of heart failure has largely been approached with either a mechanical or biological strategy, but in the past few years, the idea of combining mechanical support and cellular therapy synergistically has emerged ...

    • Pneumatic Networks for Soft Robotics that Actuate Rapidly 

      Mosadegh, Bobak; Polygerinos, Panagiotis; Keplinger, Christoph; Wennstedt, Sophia W; Shepherd, Robert F.; Gupta, Unmukt; Shim, Jongmin; Bertoldi, Katia; Walsh, Conor J; Whitesides, George McClelland (Wiley-Blackwell, 2014)
      Soft robots actuated by pressurization and inflation of a pneumatic network (a “pneu-net”) of small channels in elastomeric materials are appealing for their ability to produce sophisticated motions with simple controls. ...

    • Soft robotic sleeve supports heart function 

      Roche, Ellen; Horvath, Markus; Wamala, Isaac; Alazmani, Ali; Song, Sang-Eun; Whyte, William; Machaidze, Zurab; Payne, Christopher; Weaver, James C.; Fishbein, Gregory; Kuebler, Joseph D.; V.Vasilyev, Nikolay; Mooney, David; Pigula, Frank Alexander; Walsh, Conor J (American Association for the Advancement of Science (AAAS), 2017-01-18)
