According to data from the World Health Organization, more than one billion people—roughly 16 percent of our global population—navigate daily life with some form of disability. For many, physical challenges significantly restrict personal independence, mobility, and self-expression. However, a new generation of embedded developers, robotics engineers, and hardware hackers are rising to meet these challenges with empathy and accessible design.
At the Regeneron International Science and Engineering Fair (ISEF) in Phoenix, the IEEE Foundation celebrated this forward-thinking spirit by presenting the annual IEEE Presidents’ Scholarship awards. Under the guidance of IEEE President Mary Ellen Randall, three outstanding high school students were honored for their groundbreaking work in human-computer interfaces, mind-controlled prosthetics, and rugged terrain navigation. Let's take a deep look at the hardware, software, and mathematics powering these incredible innovations.
1. Tonguage: Vision-Based Human-Machine Interface
Securing the top spot and a $10,000 scholarship, sophomore Lynn Bowlby (Hollie) Tang from Wilson High School in California introduced Tonguage. Tonguage is a non-invasive, computer-vision-based human-machine interface (HMI) designed to give users with severe motor impairments full autonomous control over computers, digital interfaces, and physical electric wheelchairs.
Rather than relying on invasive implants or expensive, specialized infrared gaze-trackers, Tang designed Tonguage to run on standard, affordable laptop webcams. The system uses real-time computer vision to track facial landmarks and expressions. The core architecture uses the user's mouth as an analog joystick: tongue movements are mapped to precise cursor directions, while intuitive eye blinks function as mouse clicks. The software decodes these spatial tongue positions and continuous movement patterns into clean, actionable digital inputs.
For safety-critical environments like wheelchair navigation, Tang implemented an intelligent face-tracking and filtering algorithm. This software feature acts as an error-prevention system, locking onto the authorized user's face and actively ignoring background motion or other individuals who walk into the camera frame. By centering her design on low-cost consumer hardware, Tang aims to make assistive technologies accessible to individuals across all socioeconomic levels.
2. NeuroGait: Lower-Limb Exoskeleton Driven by EEG and CNNs
Taking second place was Partap Sidhu, a junior at Bethpage High School in New York, who developed NeuroGait. Inspired by seeing visitors struggle with mobility at a local community center that lacked elevators, Sidhu set out to design a highly accessible, mind-controlled robotic exoskeleton for lower-limb rehabilitation.
NeuroGait functions by monitoring the user's brainwaves via a custom electroencephalogram (EEG) headset. It specifically targets the Bereitschaftspotential (BP), a faint readiness potential or electrical pattern generated in the motor cortex roughly one to two seconds before a person makes a conscious decision to move. These analog brain signals are filtered, digitized, and fed into an onboard processor running a Convolutional Neural Network (CNN).
The neural network boasts an astonishing 99.9% accuracy in classifying movement intent, translating these cognitive signals into actuation commands with a system-wide end-to-end execution accuracy of 95.2% over hundreds of testing trials. Instead of using rigid, high-torque servomotors that can resist natural human movements and cause injury, Sidhu implemented custom-designed pneumatic artificial muscles (PAMs). These soft, compliant actuators contract and expand using compressed air, closely mimicking human muscle dynamics and flexing naturally with the body.
In true DIY maker fashion, Sidhu engineered and 3D-printed this entire system for just $276. In contrast, commercial medical exoskeletons typically retail between $40,000 and $100,000, illustrating how open-source methodologies and embedded engineering can drastically democratize healthcare technology.
3. Math Into Motion: A Rugged Hexapod for Disaster Recovery
Third-place honors went to Calvin Shang Hung from El Cerrito High School in California for his project, Math Into Motion: Robotic Hexapod for Hazardous Environments. Originally inspired by watching planetary rovers struggle to navigate the loose, rocky soil of Mars, Hung developed a six-legged robot designed to traverse unstable, hostile terrain that would stall wheeled rovers or endanger search-and-rescue teams.
Without any prior electrical engineering experience, Hung taught himself PCB design, CAD modeling, firmware coding, and precision soldering. He engineered a robust hexapod capable of utilizing a stable tripod walking gait, where three legs remain firmly anchored to the ground while the remaining three swing forward. This provides an incredibly stable platform for entering collapsed structures or crossing earthquake debris zones to transport essential medical supplies.
The hexapod’s fluid physical locomotion is achieved through three core mathematical concepts:
- Inverse Kinematics (IK): Translates desired spatial coordinates of each foot into specific target angles for the corresponding joint servomotors.
- Linear Interpolation (LERP): Smooths out transitions by breaking discrete movements down into micro-steps, preventing sudden mechanical jerks.
- Euclidean Transformations: Corrects the directional vectors of individual legs depending on the chassis' global orientation, ensuring uniform movement regardless of the direction a leg is facing.
Hung’s journey illustrates the classic prototyping cycle of a hardware developer. After seven months of development, a catastrophic power rail failure on his third-generation PCB almost brought the project to a halt. Instead of giving up, he refactored his schematics, simplified the design, and assembled a fourth-generation board that successfully walked across his workshop floor. His work serves as an inspiring reminder to students and DIY makers of the rewards of persistent iteration.
Bridging Technology and Empathy
These outstanding young makers highlight a powerful truth in modern engineering: technical prowess is at its most impactful when coupled with deep empathy. By combining accessible software frameworks, affordable consumer hardware, and custom-designed PCB architectures, these innovators are showing how student engineers can build life-changing systems. For the global Maker and developer community, their designs provide excellent case studies on how creative problem-solving can solve real-world problems on a budget.
