My project is a replica of an automated car garden. I used a Greenhouse Kit, BBC MicroBit and a Sphero-RVR rover. I programed the vehicle to travel to different colored squares, which would represent different zip codes in food desert communities. The vehicle would deliver fresh fruits and vegetables to these communities, minimizing food disparities.

My project tracks and shows the progress of a Parkinson's patient in an app using the HandPD dataset with a VGG16 transfer learning model prototype.

In this project, I studied the possibility of harvesting the mechanical force of the vehicles on the road as a form of clean energy. According to Newton’s Third Law, the vehicles move forward by pushing back on the road. If the road is fitted with equipment that can convert this mechanical force into electrical energy, then it will result in a form of abundant clean energy.

Piezoelectricity is a phenomenon that converts mechanical stress into electrical force. When some materials like quarts are subjected to mechanical stress, they exhibit an electrical polarity across their two ends. When this voltage difference is applied to a circuit, an electrical current flows through it.

I conducted experiments to measure the relationship between the mechanical force and the generated electrical voltage using a toy car and a piezoelectric tile. I varied the load on the car and its speed and measured the resulting force using a spring balance. I made the car run over the piezoelectric tile and measured the generated voltage using a multimeter.

From my experiments, I found that the greater the force applied on a piezoelectric tile, the more the voltage generated. This is very useful because speeding vehicles exert a great deal of force on the road. If piezoelectric materials are embedded under the road surface, they can generate a very large amount of electrical energy.

Therefore, this project helped discover a new source of clean energy.

Using neglected cardboard boxes, I mixed cardboard with silicone to make a final rubber floor mat and heat insulating pad
