2. Executive Abstract
The primary objective of this project is to engineer a highly accurate, cost-effective Digital
Radar System capable of real-time spatial object detection. Currently, commercial
360-degree sensors and LiDAR systems utilized for obstacle detection in autonomous robotics
or small-scale security are prohibitively expensive and resource-heavy.
We will design a hardware module utilizing a microcontroller (such as an Arduino or ESP32),
paired with an ultrasonic or ToF (Time-of-Flight) sensor and a servo motor. The captured spatial
data will be transmitted via serial communication to a host computer and visualized through a
custom Graphical User Interface (GUI) mimicking a traditional radar screen. This system will
deliver high-performance, low-latency obstacle mapping, providing a strategic advantage for
lightweight robotic navigation and perimeter security monitoring.
3. Problem Statement & Contextual Background
●​ Current State/Baseline: Today, entry-level autonomous rovers and small-scale security
systems rely heavily on static infrared or ultrasonic sensors. These setups typically focus
on a fixed directional vector, failing to provide comprehensive, multi-directional
environmental data.
●​ The Core Bottleneck: Commercial 360-degree radar or LiDAR systems require heavy
capital investment and utilize complex data processing protocols. This creates a massive
bottleneck for student researchers and independent developers attempting to scale local
projects.
●​ Downstream Impacts: Relying on standard directional sensors leaves significant blind
spots. Left unaddressed, these blind spots result in increased physical collision risks for
moving robotics, critical operational delays in navigation algorithms, and incomplete
perimeter mapping in security deployments.
4. Technical Approach & Implementation Architecture
Execution is divided into two primary vectors: hardware assembly and software-driven data
visualization.

7. Acceptance Criteria & Final Handover Benchmarks
●​ Functional Compliance: The integrated hardware and GUI must run continuously for a
1-hour test cycle without serial communication drops or application freezes.
●​ Quantitative Sign-Off: Distance measurement deviations must remain below a 5% error
threshold, and end-to-end data latency (from sensor read to GUI render) must clock in at
under 100 milliseconds.
●​ Documentation Assets: Delivery of complete schematic blueprints, compiled codebase
files, and an operational handover manual.​
