Our project goal was to make a robotic sprinkler system that can detect soil moisture content and check online weather forecasts to determine whether the ground needs to be watered. After completing our product, we were able to meet all of our requirements.

The two main parts of this design are the sprinkler robot and the base station. The base station checks the weather forecast to determine if the chance of precipitation is low enough to warrant watering for the day. If the chance of rain is high enough, then the robot will not be deployed; otherwise, it will send the robot out to measure the soil moisture at specific points on the lawn. The sprinkler robot measures the soil moisture by deploying a two-point-probe into the ground to measure resistance. This data is then sent wirelessly to the base station where it determines whether or not to water that area. If it is determined the area needs watering, then the robot will turn on its sprinkler system and water the area until the base station tells it to stop. After that, the robot moves on to the next area that the base station tells it to go to. When the robot is finished, it returns to the base station.

This product is commercially viable because it is a smart watering system that does not require the installation of multiple expensive pipes and probes. It both reduces the water waste of a traditional sprinkler system while still allowing for it to be transported to a new location.

Drum Tutor Lite

Featured Project

Team: Yuanheng Yan, Zhen Qin, Xun Yu

Vision: Rhythm games such as guitar hero are much easier than playing the actual drums. We want to make a drum tutor that makes playing drums as easy as guitar hero. The player is not required to read a sheet music.

Description: We will build a drum add-on that will tutor people how to play the drums. We will make a panel for visual queue of the drum and beats in a form similar to guitar hero game. The panel can be a N*10 (N varying with the drum kit) led bar array. Each horizontal bar will be a beat and each horizontal line above the bottom line will represent the upcoming beats.

There will be sensors on each drum that will fire when the drum heads is hit. The drums will be affixed with ring of light that provides the timing and accuracy of the player according to the sensors.

Of course with a flip of a switch, the drum could be a simple light up drum: when the player hits the drum, that particular drum will light up giving cool effects.

The system will be on a microprocessor. Or for more versatile uses, it could be connected to the computer. And a app will be written for the tutor.
