Dirty surroundings impose a detrimental effect on the beauty of our environment. Hiring and paying for a large workforce to clean the debris on the roads, parks, and streets is a costly and tiring job. This project has been carried out to design and fabricate a battery-powered road-sweeper vehicle (RSV), equipped with a scrubber system. The proposed machine, equipped with scrubbers, increases the operational time while decreasing the operational cost. In contrast with typical industrial counterparts, an eco-friendly road-sweeper machine is presented in this study.

This paper presents an automatic system for sorting and grading lemons using computer vision. It eliminates human errors in sorting processes. Lemons are sorted into three categories; ripe, semi-ripe, and a combined class of defective and unripe. A camera is used to capture an image of the lemon, and image analysis is done using Raspberry Pi. A conveyor belt system and a mechanical pusher put the lemon into its respective class.
