Universal Bike Sharing Lock

Problem Statement: Prof. Varshney proposed for a ride-sharing service for mopeds and scooters, similar to existing ones for bicycles, due to their similar versatility, but faster travel in urban areas. There isn’t a true leader or standout service for moped sharing at the moment, even though there is a good amount of potential benefits in the service.

Proposed Solution: Our solution steps back a bit and looks more at the sharing portion of Prof. Varshney’s idea. Rather than build a custom vehicle to use for a ride sharing service, we intend to create an electronic lock system for ride sharing that works, independent of the type of ride being used. Our idea is to make a Universal Bike Sharing Lock to use for bikes, scooters, and mopeds.

ECE445 Plan: There are three blocks to the project:
A lock box that houses a normal bike wire lock (and the main electronic components). It can be locked and unlocked using a push-pull solenoid (controlled by the amount of voltage going into it), using a microcontroller to manage this.

A communicating device that can connect a phone to the Sharing Lock (either via web or Bluetooth). The user can then lock and unlock the box (and thus the bike or scooter) based on the ride sharing conditions (handled by software), and track its location and travel.

A software ride share handling system (either a web app or a mobile app). This can manage the actual locking and unlocking of the box, and would be used for paying and managing bikes in practice.

Uniqueness: Unlike other similar bike/scooter sharing services, no custom vehicle is needed to utilize this service. Any sort of bike, scooter, or moped that can be secured with a typical bike lock can connect with this sharing service. The Universal Bike Sharing Lock not only increases the potential rides that can be tracked and secured, but also increases the scope and usability of the bike sharing service.

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.
