To achieve the first goal, we will utilize shear thickening fluid, which exhibits shear thickening effects. This property allows the fluid to dissipate a significant amount of energy under impact, slowing down high-velocity objects and protecting them from destruction. By implanting electrodes into the shear thickening fluid, the apparatus can detect changes in resistance of the fluid. Using the specific relationship, we aim to calculate the speed of the object being caught. Finally, the mechanical hand can adjust its strength based on the speed of the subject to catch it. Development of Bioinspired Tactile Sensor Supervisor: SHEN, Yajing / ECE Student: RA, Hoonjoo / CPEG Course: UROP1100, Spring In order to provide the multi-dimensional scope of force detection to the targeting system, the inputting force must be analyzed into three orthogonal vectors. The tactile sensor aims to analyze the input force in the set of one-dimensional normal force and two-dimensional shear force. To achieve such an analysis, a piezoresistive pressure sensor and vision-based marker tracking method were selected respectively. Its simple, yet highly modifiable design is expected to give it the flexibility in applying to many other systems that require different scales and resolutions of force detection. Currently, the normal force distribution measurement in the Newton scale has been implemented successfully in an array of 3*3, (scale: 15 mm * 15 mm for each sensing unit and 60mm * 60mm of the entire sensing area, root mean square error(RMSE) of 0.019 Newton), and sheer force detection is in a state of calibration.

From small-scale applications such as door access control, to large-scale applications such as warehouse storage. RFID plays a vital role in identification and localization and is widely adopted. Because of RFID’s cheap, easy to program property, RFID can also be a powerful educational tool for students to learn the basics of coding and algorithm interactively. This report describes our work in the Undergraduate Research Opportunity Program in the 2022 Fall. We have established some fundamental software engineering practices and deployed them in development. More results shall be produced in the Winter Semester.
