Many small insects such as water striders can leap from water surface. Inspired by their jumping capability, we present the design of a novel, miniature, water surface jumping robot in this paper. Jumping from water surface is more challenging than jumping from ground due to the liquid water surface. We address this problem by using carbon fiber strip to store energy, two wings to flap the water surface,...
Atomic Force Microscopy (AFM) is a powerful and popular technique of single-molecule imaging both in air and liquid. Recent research and hardware development provide AFM with the function of manipulation nano-particle and modify sample surface in nano-scale. However, due to AFM usually takes several minutes to get an image and the surface change is hard to observe in real-time manipulation. In this...
Mobile sensors with jumping ability provide several advantages compared with the traditional wheeled sensors such as ability to move in rugged terrain. A controllable jumping robot for this purpose is described in this paper. The robot has dimension about 9.5cm × 9cm × 3cm and weighs 54.1 grams. It can perform the jumping process continuously. This paper focuses on the mechanisms to achieve such a...
The fruit fly Drosophila is one of the most important model organisms in genetics and developmental biology research. To better understand the biomechanical properties involved in Drosophila embryo research, this work presents a mechanical characterization of living Drosophila embryos through the stages of embryogenesis. Measurements of the mechanical forces of Drosophila embryos are implemented using...
To better understand the biomechanical properties involved in Drosophila embryo research, this work presents a mechanical characterization of living Drosophila embryos through the stages of embryogenesis. Measurement of the mechanical properties of Drosophila embryos is implemented using a networked human/robot cooperative interface featuring a novel, in situ, and minimally invasive piezoelectric...
The objective of this paper is to investigate the force behavior and elasticity (plasticity) of living Drosophila embryos at different stages using an in situ PVDF (polyvinylidene fluoride) piezoelectric micro-force sensor with sub-muN resolution. The Drosophila embryo is one of the most studied organisms in biological research, medical research, genetics and developmental biology, and has implications...
