Performing overhead tasks with supernumerary robotic limbs
… risk of injury, a set of supernumerary robotic limbs (SRL) were designed to perform these overhead tasks. The SRL is designed with limits in the hardware and software to protect the human and prevent collisions between robot and operator. The arms are designed to have a workspace above and in …

Design and control of supernumerary robotic limbs
… remarkable ability to control their four natural limbs in a voluntary, accurate and independent manner. The simultaneous use of two or more limbs allows humans to learn and robustly perform a wide range of complex tasks. Since the use of multiple limbs enables humans to master advanced motor …

The Effects of Retinoids on Regenerating Axolotl Limbs
The limbs of amphibians normally regenerate only those parts distal to the amputation plane, an observation that has been formalized as the rule of distal transformation. The basis for this rule is the inheritance by the blastema of a cellular memory of its position of origin, termed positional …

Characterizing grippers for transmitting prosthetic device for upper limbs
In this thesis, I designed and tested various fingertip grippers for a wearable force transmitting prosthetic device. This device uses fluid displacement to provide force feedback to the user, allowing the user to feel how much force they are gripping an object with. The device consists of two …

Imaging of residual limbs using motion processing with IMUs
Accurate imaging of residual limbs is necessary for the design of well-fitting sockets for prosthesis wearers. Unfortunately, current methods of acquiring residual limb geometry are often expensive and inaccessible. A measurement method is proposed using coordinated IMUs to achieve residual limb …

Design and Control of Mechanoneural Interfaces for Neuroprosthetic Limbs
… of preserving afferent feedback in residual limbs on the sensorimotor responses of individuals with below-knee amputations. Additionally, we present a neuroprosthetic framework that fully reconstructs biomimetic gait from neural information generated by individuals with below-knee amputation. …

Supernumerary Robotic Limbs for Next Generation Space Suit Technology
… of wearable robots, called Supernumerary Robotic Limbs (SuperLimbs), which would be mounted on the xEMU’s Square Boss Interface (SBI), positioned such that each SuperLimb is on either side of the astronaut’s center of mass. The use of SuperLimbs during an EVA allows the astronaut to safely and …

Supernumerary robotic limbs : biomechanical analysis and human-robot coordination Training
… to these issues - the Supernumerary Robotic Limbs (SRL). These limbs could potentially increase the workspace of the human operator to him more efficient, as well as reduce the load on the human while he performs staining tasks. It accomplishes this by providing the worker with extra arms in …

Supernumerary robotic limbs for human augmentation in overhead assembly tasks
Manufacturing tasks are highly demanding of work, and there is an especially high prevalence of injury associated with overhead tasks which are taxing to the shoulder and upper body. To assist workers completing these tasks, and to increase overall productivity, safety and effectiveness, we …

Phantom Limbs: Urban history and the generation of built form
Throughout the process of trying to manage decisions and objects coming together in a designated area of the city, questions are faced that are generated by more than one set of circumstances, the many histories of a place, its geology and typology and topology, the balance of pragmatism and …

COST OF TRANSPORT, LOWER LIMBS ASIMMETRY AND THE DYNAMICS OF RUNNING.
… agreement between the actions of the lower limbs and general this assumption was adopted to simplify data collection and analysis of the lower limbs. Gait asymmetry instead, does not appear to be the consequence of abnormality, but rather reflects natural functional differences between the …

Design and control of Supernumerary Robotic Limbs for near-ground work
Supernumerary Robotic Limbs (SRLs) are a recent form of robot that augment natural human abilities through the addition of body-mounted robotic appendages which can move independently of the wearer. This thesis provides a detailed analysis of the MantisBot, an SRL morphology that provides a wearer …

Control of a pneumatically actuated joint for wearable supernumerary robotic limbs application
… on the development of the Supernumerary Robotic Limbs project, headed by Federico Parietti in the d'Arbeloff Labs under Prof. Harry Asada. Specifically, this paper focuses on the integration of lightweight, pneumatic systems for prismatic joint actuation, and the various control schemes studied. …

Mechanical and trajectory design of wearable Supernumerary Robotic Limbs for crutch use
The Supernumerary Robotic Limbs (SRL) is a wearable robot that augments its user with two robotic limbs, kinematically independent from the user's own limbs. This thesis explores the use of the SRL as a hands-free robotic crutch for assisting injured or elderly people. This paper first details the …

Non-contact quantitative imaging of limbs, bone and tissue, using ultrasound tomographic techniques
Non-contact and quantitative ultrasound images of bone and soft tissue are produced from original algorithms applied to observational data sets collected on two custom built ultrasound imaging systems for limb imaging. The images are quantitative in that the distribution of sound speeds and …

Optimization of vacuum pump device for use in rapid fitment of prosthetic limbs
Developing World Prosthetics NGO has been in contact with the Jaipur Foot Organization in order to create a human powered vacuum pump for a new technique in prosthetic fitment. The new technique would provide mobility to fitment camps due to the non-reliance of an electrical grid. The design …
