Wouldn't the small solar robot have to move pretty fast in order for the blade to be able to cut through grass? I can't imagine cutting grass very effectively by just (manually) dragging a knife through it, it will just bend out of the way instead of cut won't it?
- swores 1y agoWell scythes are a typical way to cut grass, and they are basically just swinging a blade to do it - they just use a long handle to make it easy to move the blade fast enough. https://m.youtube.com/results?search_query=scythe+grass+cut https://m.youtube.com/results?search_query=scythe+grass+cut (I've no idea about the physics of required speed or blade sharpness, so don't know how feasible or not a robot cutting this way would be.)
- deckar01 1y agoI am imagining razor blades arranged like Vs. They don’t necessarily have to cut horizontally either. Cutting upwards would exploit the tension of the roots rather than overcoming the inertia mass of a blade of grass.
