Structure And Design

A four-fingered metamorphic robotic hand with a reconfigurable palm is presented in this paper with the application in deboning operation of meat industry. This robotic hand has a reconfigurable palm that generates changeable topology and augments dexterity and versatility for the hand. Mechanical structure and design of the robotic hand are presented and based on mechanism decomposition, kinematics of the metamorphic hand is investigated with closed-form solutions leading to the workspace characterization of the robotic hand. Based on the kinematics of the four-fingered metamorphic hand, utilizing product-of-exponentials formula, grasp map and grasp constraint of the hand are then formulated revealing the grasp robustness and manipulability performed by the metamorphic hand. A prototype of the four-fingered metamorphic hand is consequently fabricated and integrated with low level control and sensor systems leading to a scenario of applying the hand in the field of meat industry for deboning operation.

The Brain

Retinal degenerative diseases are characterized by the loss of photoreceptor cells within the retina and affect 30-50 million people worldwide. Despite the availability of treatments that slow the progression of degeneration, affected patients will go blind. Thus, there is a significant need for a prosthetic that is capable of restoring functional vision for these patients. The protein-based retinal implant offers a high-resolution option for replacing the function of diseased photoreceptor cells by interfacing with the underlying retinal tissue, stimulating the remaining neural network, and transmitting this signal to the brain. The retinal implant uses the photoactive protein, bacteriorhodopsin, to generate an ion gradient in the subretinal space that is capable of activating the remaining bipolar and ganglion cells within the retina. Bacteriorhodopsin can also be photochemically driven to an active (bR) or inactive (Q) state, and we aim to exploit this photochemistry to mediate the activity of pixels within the retinal implant. In this study, we made use of a novel retinomorphic foveated image sensor to characterize the formation of active and inactive pixels within a protein-based retinal implant, and have measured a significant difference between the output frequencies associated with the bR and Q states.
