— This paper describes a truss climbing robot we designed and prototyped. The robot has a minimalist design with three motive degrees of freedom that enable movement along three-dimensional truss structures. This robot can form a six-degree-of-freedom structure by connecting to another identical module using a passive bar as a medium. We present the design(More)
Multiphoton microscopy (MPM) is a nonlinear fluorescence microscopic technique widely used for cellular imaging of thick tissues and live animals in biological studies. However, MPM application to human tissues is limited by weak endogenous fluorescence in tissue and cytotoxicity of exogenous probes. Herein, we describe the applications of moxifloxacin, an(More)
Moxifloxacin and gatifloxacin are fourth-generation fluoroquinolone antibiotics used in the clinic to prevent or treat ocular infections. Their pharmacokinetics in the cornea is usually measured from extracted ocular fluids or tissues, and in vivo direct measurement is difficult. In this study multiphoton microscopy (MPM), which is a 3D optical microscopic(More)
Ionizing radiation (IR) injury is tissue damage caused by high energy electromagnetic waves such as X-ray and gamma ray. Diagnosis and treatment of IR injury are difficult due to its characteristics of clinically latent post-irradiation periods and the following successive and unpredictable inflammatory bursts. Skin is one of the many sensitive organs to IR(More)
A truss climbing robot has been extensively investigated because of its wide range of promising applications such as construction and inspection of truss structures. It is designed to have degrees of freedom to move in three-dimensional truss structures. Although many degrees of freedom allow the robot to reach various position and orientation, it causes(More)
— We explore the concept of self-assembling robot systems consisting of simple passive structural modules plus active robotic modules. In particular, we consider a space of 2-and 3-DOF robots with rotating grippers which attach to passive structural bars. The resulting systems range from a passive truss with one independent active climbing module to fully(More)
