This paper presents a vision-based force estimation strategy using compliant 3D-printed micromanipulative end-effectors. These passive tools, which introduce increased flexibility to the task, can also be used as integrated force sensors using vision-based tracking. The main contributions of the work include two main aspects. Firstly, an investigation into the effects of manufacturing parameters on...
This work presents the initial characterization of planar silicon pin-joints for use in linkages for walking microrobot legs. A major goal in walking microrobotics is the creation of robust leg structures driven by low-power motors capable of lifting a 20mg mass and propelling it forward. Hinged joint structures, rather than stiff flexures, are ideal for this task. However, since joints are not fully...
Geophysical prospecting for petroleum exploring and nature disaster forecasting depend on the broadband seismic sensors. Broadband electrochemical seismic sensor has superior performance such as high sensitivity at low frequency and no mechanical noise. These advantages make it widely used in seismology. This paper firstly studied the effect of the elasticity coefficient of the spring on the frequency...
