In order to release the fertilizer production workers working in high dust and strong corrosive environment for a long time, a sampling robot was designed. By analyzing the using demand, robot’s designing principles including characteristics of impact resistance, corrosion resistance, cleaning by itself, transmission mechanism builtin and drive away from the end piece installed was proposed. From the angle of bionics, the crab joints’ structure characteristic was researched. Then sampling robot configuration was proposed. Bionics function and structure was designed. According to its operation condition, motion process and control plan was designed. After the parametric optimization,its feasibility was validated by simulation and impact test.
