Utilizing this fact, we design a vehicle, equipped with a dual-wheel steering system, moving in a dense quasi-2D granular medium of ping-pong balls. The steering system is able to disturb the jammed area and allows the vehicle to move easier and alter its moving direction freely. We also present preliminary results of the vehicle moving against gravity in a 3D environment.2159730 bytesapplication/pdf論文公開時間: 2019/8/26論文使用權限: 同意有償授權(權利金給回饋學校)顆粒介質力學滯塞重力效應車輛轉向機構系統granular mediajamminggravity effectvehiclesteering system搭載二輪轉向機構之車輛於準二維密集球體介質中行進及爬坡性能之研究Vehicle moving against gravity with a dual-wheel steering system in shallow dense granular mediathesis10.6342/NTU201600886http://ntur.lib.ntu.edu.tw/bitstream/246246/278303/1/ntu-105-R03522125-1.pdf
