The Challenge of Infrastructure Compliance

For many, a small crack in the pavement or a slightly too-steep incline is a minor inconvenience. However, for individuals with mobility impairments, these architectural flaws can represent significant barriers to independence and access. While the Americans with Disabilities Act (ADA) provides guidelines for accessibility, manual audits of thousands of feet of sidewalk are labor-intensive, prone to human error, and often infrequent.

The UE student-led project seeks to move beyond static, periodic audits toward a dynamic, data-driven model of infrastructure assessment. By automating the process of scanning, the team aims to provide facility managers with a comprehensive and accurate map of where accessibility fails, allowing for prioritized repairs based on actual data rather than anecdotal reports.

Technical Framework and Functionality

The robot functions as a mobile sensing platform. By integrating a suite of sensors—likely including LiDAR (Light Detection and Ranging), high-resolution cameras, and accelerometers—the device can traverse campus pathways and record the topography of the ground in real-time.

• Surface Discontinuities: Identifying cracks, potholes, or upheavals caused by root growth that could trip a pedestrian or snag a wheelchair caster.

• Slope and Gradient: Measuring the pitch of ramps and sidewalks to ensure they remain within the legal and functional limits required for unassisted wheelchair navigation.

• Obstacle Detection: Mapping permanent or semi-permanent obstructions that narrow the available path of travel below required widths.

As the robot moves, it analyzes the surface for specific anomalies. These include

The data collected by the robot is then processed to create a digital twin or a "heat map" of the campus. This allows administrators to visualize the most problematic areas of the campus layout, turning abstract accessibility concerns into a tangible list of actionable maintenance tasks.

The Role of Student Innovation

This project highlights a shift toward applied engineering within the university setting. Rather than focusing solely on theoretical models, the students have engaged in an iterative design process, building a prototype that must operate in the unpredictable environment of an active campus. The development process involves not only mechanical engineering and robotics but also software development to handle the large volumes of spatial data generated during scans.

By taking ownership of this project, the students are applying their academic training to solve a real-world societal problem. The intersection of robotics and social equity demonstrates how emerging technologies can be leveraged to foster inclusivity.

Broader Implications for Urban Planning

While the current focus is on the University of Evansville campus, the implications of this technology extend to municipal governance. City governments often struggle with the sheer volume of sidewalk mileage they must maintain. A scalable version of the UE scanning robot could allow cities to conduct comprehensive accessibility audits in a fraction of the time required for manual inspections.

Furthermore, such a system could be integrated into a proactive maintenance schedule. By scanning sidewalks periodically, cities could detect the early stages of pavement degradation before they become hazardous barriers, shifting the paradigm from reactive repair to preventative maintenance.

Ultimately, the project serves as a proof of concept for how automated scanning can ensure that the built environment is accessible to all, regardless of physical ability, ensuring that the right to movement is not hindered by preventable infrastructure failures.
