Design an elephant-inspired litter vacuum vehicle for waste collection in small outdoor communities. The vehicle should integrate the visual and functional characteristics of an elephant, such as a trunk-like suction hose for collecting litter, mimicking the reach and flexibility of an elephant's trunk. It must be compact, maneuverable, and suitable for narrow pathways, with a maximum width of 1 meter. The design should include an eco-friendly power source (e.g., rechargeable battery or solar panels), a waste collection tank with a minimum capacity of 100 liters, and a user-friendly interface for operators. Emphasize ergonomic design for operator comfort and efficient litter collection, incorporating low noise levels to minimize disruption. Visualize the exterior design with elephant-inspired aesthetics. Highlight how this design meets the waste management needs of small, environmentally conscious communities
