Structural Design and Analysis of Slope Weeding Robot

With the development of The Times, urban greening has become a very important indicator. Weeding robots are also gradually entering the greening industry. However, when weeding on slopes, they still face difficulties such as easy slipping during slope operations, low operation safety, and low weeding efficiency. This paper analyzes the structure of the weeding robot by using the operation demand decomposition method and idealized models to address problems such as easy slipping on slopes, low operation safety, and difficulty in weeding. It also optimizes the design of related structures to break through terrain limitations and achieve precise weeding. In the hard-ware design of the slope weeding robot, the walking system adopts a multi-wheel independent suspension structure to enhance the passability of the weeding machine. In the overall layout, the center of gravity is lowered in advance to enable it to run on slopes and maintain the stability of the vehicle body. When choosing weeding tools, a high-speed rotating grass cutting line structure is adopted, which has a higher weeding efficiency and causes less damage to the environment. The energy source is mainly high-capacity lithium batteries, which can meet the single-charge battery life of 4 to 8 hours.
