Our goal is to design a bicycle device that could detect the physical condition and will sent alert if the physical condition fell below a threshold.

Features:
Generate electricity from mechanical source of bicycle to power the detector
Heart rate sensor (and a bio-related sweat sensor) will be inside the bike handle
The pressure sensor will be built in the saddle and both pedals
The accelerometer will be used for collision detection

Function: All sensors are connected to the power system (from mechanical energy) by wires, but they also have a secondary battery. The sensor in bike handle can check the heart rate and (salt %) to determine if the biker is in a safe physical condition. When the sensor notices it after analyzing the data, it can alert the biker to stop or to take a rest. The volume of the alert will be gentle and increase gradually.
If all pressure sensors detect pretty small value, the system will consider that the person is thrown off the bike unless he or she hits the button on the bike. We also implement a delayed emergency response system that gives enough time for user to cancel it. This feature is set to off at the beginning, the biker can choose whether to open it. For example, they can only use this feature when they are going to cycle in the some unsafe places or somewhere with few people. The collision detector will analyze the change of acceleration.

Amphibious Spherical Explorer

Featured Project

The amphibious spherical explorer (ASE) is a spherical robot for home monitoring, outdoor adventure or hazardous environment surveillance. Due to the unique shape of the robot, ASE can travel across land, dessert, swamp or even water by itself, or be casted by other devices (e.g. slingshot) to the mission area. ASE has a motion-sensing system based on Inertial Measurement Unit (IMU) and rotary magnetic encoder, which allows the internal controller to adjust its speed and attitude properly. The well-designed control system makes the robot free of visible wobbliness when it is taking actions like acceleration, deceleration, turning and rest. ASE is also a platform for research on control system design. The parameters of the internal controller can be assigned by an external control panel in computer based on MATLAB Graphic User Interface (GUI) which communicates with the robot via a WiFi network generated by the robot. The response of the robot can be recorded and sent back to the control panel for further analysis. This project is completely open-sourced. People who are interested in the robot can continue this project for more interesting features, such as adding camera for real-time surveillance, or controller design based on machine learning.
