Rain O Shine

The Rain O Shine Modular Umbrella is the answer to the phenomenon of damaged umbrellas being wasted. All parts of the umbrella can be disassembled and replaced manually, and users can also choose different functional components according to their own preferences. All parts are made of recyclable materials. This project is the application of the knowledge of circular design.

Usage Scenario

DEV Soil Fertility Detection and Automatic Fertilization Robot

This product is designed to help farmers control fertilizer use. More than 70% of farms in the world are small family farms of no more than 1 hectare. Small-farm farmers rely mostly on experience in the use of chemical fertilizers and the demand for crops, which often leads to overuse of chemical fertilizers, resulting in land pollution and low crop yields. The Dev small-farm robot can help farmers quickly detect the Nitrogen-Phosphorous-Potassium (NPK) content of the land, calculate the total required amount of fertilizer and the average amount of fertilizer according to the demand of crops, and then automatically fertilize the crops. Precise fertilization by robots can reduce soil pollution and help farmers save on fertilizer costs.

DEV Robot Usage Scenario

The robot has two working modes, soil test mode and automatic fertilization mode, which can be converted by stretching the body and adding a fertilizer box.
