WiFi Vision Programmable Robot – ESP32-CAM HD Streaming, 4-Wheel Mecanum + PID Motion, Open I/O for Sensors & Servos, Designed for Students, Teachers & Makers 8+ – Complete STEM Learning Set

This is a compact “vision + robotics + IoT” platform for classrooms and makers: ESP32-CAM streams over Wi-Fi to browser/app so learners can drive while logging ultrasonic distance, line error and speed; a 4-wheel Mecanum chassis delivers omni motion with vector decomposition, while examples build PWM-to-speed maps, PID speed/heading loops and acceleration limits; a pan-tilt head decouples view from base for “head seeks, base follows.” Sensing combines a 3-way IR array with ultrasonic ranging: line following progresses from on/off to proportional to tuned PID, and avoidance evolves from thresholds to proportional slowdown to state-machine re-entry; the track-first/override arbitration handles corridors, junctions and blind spots. Software ships with Arduino & MicroPython templates using non-blocking loops and schedulers plus serial/web streaming for logs and plots; I²C/UART/SPI headers accept IMU, encoders, OLED, BLE, GPS and gas/light sensors. Hardware uses thick plates, metal standoffs and rubber Mecanum rollers; solder-free terminals cut assembly time; tools, wiring maps, tuning sheets and troubleshooting checklists support a course flow from assembly to integrated demos. Typical uses include maze routing, path keeping, inspection, mobile vision, AGV principles and algorithm primers; batteries not included; recommended 8+ with supervision.

Wi-Fi camera live video and IoT telemetry—browser/app control for real-time driving and logging; entry-level CV with color/shape detection and frame-rate tuning; MQTT/HTTP pipelines enable cloud logs, remote parameters and alerts to teach the perceive-connect-decide-act loop. Hands-on evaluation—frame capture for ROI, threshold maps and fps–resolution trade-offs; remote panel toggles bitrate/exposure/gamma; labs compare low-light/back-light/motion-blur while logging latency, drop rate and PSNR; cloud logs with timestamps ease reproducibility and reporting.
Omni Mecanum motion with PID—forward/back/strafe/diagonal/spot-turn; examples map PWM-to-speed and tune angular/linear errors; pan-tilt decouples view from base for kinematics and path-planning labs. Engineering kinematics—matrix mapping, dead-zone compensation, acceleration/jerk limiting and anti-windup; ready-to-run point-to-point, lemniscate and S-curve trackers; same track, three controllers (open-loop/P/PID) for fair benchmarking.
3-way IR line tracking and ultrasonic ranging—stepwise control from bang-bang to PID; threshold/proportional slowdown with state-machine re-entry; track-first with obstacle override handles corridors, junctions and blind spots. Robust sensing—denoised line-error vectors, hysteresis thresholds for stable avoidance, finite-state flow with re-entry and detours; CSV exports for overshoot/MTTR; rubric-ready flowcharts and pseudocode.
Open, classroom-ready code—non-blocking loops, schedulers, serial/web streaming, PWM/servo helpers and persistent configs; I²C/UART/SPI headers welcome IMU, encoders, OLED, BLE, GPS and gas/light sensors with solder-free terminals. Course-ready architecture—task table + event bus, servo soft-start, safety guards, serial tuning scripts and web forms; built-in I²C scanner; modular repo layout for team collaboration and grading.
Thick plates, metal standoffs and rubber rollers—built to last; kit includes tools, wiring maps, tuning sheets and troubleshooting checklists for station-based teaching and contests; batteries not included; recommended 8+ with supervision. Durable and serviceable—quick-release standoffs, abrasion-resistant rollers, torque specs and tightening order; tri-axis troubleshooting for drift/jitter/skew ensures consistent classroom reliability.
