#Problem:
The city of Champaign would miss a lot of parking fee when some drivers forget or intentionally not pay the parking fee, or park in spaces they are not allowed to park in. Many of these drivers won’t be ticketed because each car has to be manually checked. Also, drivers might park in reserved spots by accident because they might have missed the sign or it’s too dark outside to read it.

#Solution:
We propose to build a smart ‘meter’ that can recognize the car plate numbers and automatically associate the plate with a violation (if one is committed), and charge a fee to that car plate. Individuals can set up accounts (linked to a license plate) to automatically be charged for parking fees, so it removes the need to carry around coins. If someone attempts to park with an empty balance, or in a spot they’re not allowed to park in, University Parking will be notified of the violation. Our smart meter would also feature an LED light that changes to different colors to indicate if a violation has been committed (e.g. Red can indicate an empty balance, time limit exceeded, too close to the meter/other car).
-------In the hardware part, for the smart meter, we would mainly handle electronic parts like a timer for calculating the fee, a camera for taking pictures of plate, led lights for signaling, several sensors for car detection, wifi for network communication between meters and the server, camera flash for taking picture at night, LCD screen displaying the time remained, proximity sensor to help car park.
-------In the software part, a server to hold user accounts and receive updates from the parking meters, and we shall work on the applications like driver registration and plate number recognition system.

#Cost:
For meters, we are using some basic electronic parts. So, the cost should be under $50 each.

Low Cost Myoelectric Prosthetic Hand

Featured Project

According to the WHO, 80% of amputees are in developing nations, and less than 3% of that 80% have access to rehabilitative care. In a study by Heidi Witteveen, “the lack of sensory feedback was indicated as one of the major factors of prosthesis abandonment.” A low cost myoelectric prosthetic hand interfaced with a sensory substitution system returns functionality, increases the availability to amputees, and provides users with sensory feedback.

We will work with Aadeel Akhtar to develop a new iteration of his open source, low cost, myoelectric prosthetic hand. The current revision uses eight EMG channels, with sensors placed on the residual limb. A microcontroller communicates with an ADC, runs a classifier to determine the user’s type of grip, and controls motors in the hand achieving desired grips at predetermined velocities.

As requested by Aadeel, the socket and hand will operate independently using separate microcontrollers and interface with each other, providing modularity and customizability. The microcontroller in the socket will interface with the ADC and run the grip classifier, which will be expanded so finger velocities correspond to the amplitude of the user’s muscle activity. The hand microcontroller controls the motors and receives grip and velocity commands. Contact reflexes will be added via pressure sensors in fingertips, adjusting grip strength and velocity. The hand microcontroller will interface with existing sensory substitution systems using the pressure sensors. A PCB with a custom motor controller will fit inside the palm of the hand, and interface with the hand microcontroller.
