Abstract: A robotic device is described. The robotic device includes segments and arms connected to a platform. A machining or another processing tool can be coupled to the platform. The segments can have one end attached to the platform and the other end attached to an attachment device. The attachment device can include an attachment surface/mechanism that can attach to a workpiece.

Abstract: A robotic catheter can include bi-stable concentric tubes and a torsional spring mechanism that can provide torque at the proximal extremity of one or more tubes. The robotic catheter can compensate for the energy that may be released by the tubes snapping from on stable-equilibrium position to another by using the energy stored in the torsional spring mechanism. The energy released by the tubes upon snapping from one stable-equilibrium position to the other can be compensated by the energy stored in the torsional spring at the base, thereby resulting in the first, energy-free, zero stiffness catheter system that (1) synchronizes with the motion of the heart and (2) naturally results in optimal, pseudo-constant contact force with the tissue.

Abstract: A 3D microfluidic device for use as an in vitro lymph node is described. The microfluidic device has a body with a semi-circular inner wall and a first channel located adjacent along the semi-circular inner wall, the first channel corresponding to a subcapsular sinus region of a lymph node, a second channel located adjacent the first channel, the second channel corresponding to a reticular network, and a bottom cavity and top cavity, centrally located, corresponding to a paracortex and follicle of a lymph node, respectively. The various compartments of the device are separated by circumferentially and horizontally located rows of micro-pillars. A lab-on-a-chip device incorporating the microfluidic device is also described.
