    3Virtual reality can be used to treat a number of psychological issues but is only available in research labs and not on a consumer level. This project provides a customizable suite of therapeutic virtual reality environments for a consumer-level VR device, the Oculus Rift. This project’s three modules have been built to help people with acrophobia, social anxiety and general anxiety and stress. Each can be customized to the user’s needs. Created to be available at the lowest-possible cost.

    4Robotic arm that mimics the user, who is wearing an exoskeleton fitted with motion capture sensors that send data wirelessly to the arm. The arm receives the position data and mimics the user. Sponsored by Hewlett Packard, this human-controlled robot allows for an employee to fix machines remotely at the company home base instead of traveling offsite to fix the broken machine in person. Different from other systems because it uses motion capture technology (versus a joystick or controller) to control the robotic arm.

    5A control module for Limbitless Solutions’ bionic arms that allows for full wireless configuration of the arm over Bluetooth via mobile application. Includes embedded EMG, accelerometer, gyroscope and servo leads with variable hardware and software thresholding, in addition to an LED array. Made to provide tools for future development and features fully functional embedded operating system, backend server for data analysis and modular hardware design.

    6Aims to help people with Arthrogryposis Multiplex Congenita, a curvature of joints that limits a person’s limb mobility. This is a control system for a joint electrical-mechanical exoskeletal arm. The arm assists with mobility with a first-of-its-kind hybrid design. It will be actuated by a stepper motor and cable drive to simulate the elbow movement and a pneumatics system for hand control. Will be built for wheelchair users in first iteration, but can be upgraded to a future portable prototype. Sponsored by Limbitless Solutions.

    7A charging apparatus for electric vehicles on the road to increase battery longevity and efficiency, to ultimately increase travel distance. Employs a wireless charging system built under the track (road). The robot (car) has a built-in receiver to gather the wireless energy being resonated from under the track. This is a new and improved way of charging a vehicle to eliminate stopping and charging the vehicle for hours before the next use.

    8A system of solar powered lawn spikes and a central hub that greets a person walking to the front door of a residence with a music and light show. Sensors detect a person within a certain distance of the spikes and sends an alert to the central hub. Increases curb appeal and also can be used in the backyard for additional entertainment value. Could also be adapted for home security.

    9A chair that reminds the user to maintain good sitting posture and take regular breaks. It measures a user’s posture while they are sitting in the chair and provides feedback through the chair and a companion app.

    10Designed for smaller airports that do not have Fixed Base Operators who provide pilots with current wind information and perform transmission radio checks with pilots to ensure communications systems are working properly. Current systems in use at airports cost $75,000, but this prototype can be produced under $500. Uses a Raspberry Pi interfaced with a printed circuit board (PCB), wind station and VHF radio. Tested at Apopka Airport.

  • blw_7989

    11A mobile entertainment system that uses solar cells to actively collect and manage power. From this device, a person can play music via Bluetooth, cool beverages, control lighting and charge mobile devices. Designed to go anywhere and bring the party with it.

  • blw_7992

    12Aesthetic LED matrix, cup sensor system, ball tracking system, sterilization system and a foul line. Centrally controlled by a Raspberry Pi that will be connected to the system. This project improves on what’s current table-based game tracking because it creates a more efficient way of tracking rule-breaking and score keeping while providing a clean, fun environment.

  • blw_7994

    13A powered assistive device for users who have limited to zero upper limb mobility. Sponsored by Limbitless Solutions, whose previous projects have assisted people with missing limbs. This project helps people who have limbs that are mobility impaired. Produced primarily through 3-D printing to allow design to be fitted to anyone at a fairly inexpensive production cost.

    14Provides quantitative volumetric flow rate data and visual representation of a toilet leak rate. Sponsor is Guard Dog Valves. Flow rate measurement system uses a continuous fluid level sensor to measure volumetric flow over time. The sensor measures the fluid level based on the change in resistivity as the water height increases.

  • blw_8000

    15Assists people with clenched hand symptom. Allows person to open their hands to be able to grab objects. Rehabilitates defective muscles. Employs springs, rods and bands to provide an opposing but flexible force to the constant force that causes a hand to clench. Sponsored by Limbitless Solutions.

  • blw_8002

    16Solves the cargo carry problem experienced by farmers in Kenya. Efficient way of transporting fruits and vegetables over rough terrain. Employs a hanging system of “hammocks” where produce will be safeguarded from damage when traveling through rough terrain by use of flatbed or bicycle attachment.
