ESP32 Vision Gimbal First Stream and Tracking Guide

This guide is for the black and blue ESP32 vision gimbal kits. The first goal is not “AI tracking” immediately. The first goal is a stable camera stream, clean power, predictable servo movement, and a repeatable test scene.

Hardware check

• Confirm the ESP32 camera module is seated correctly and the ribbon is not twisted.
• Check the gimbal frame before power. It should move by hand without binding.
• Use a supply that can handle WiFi and servo movement together.
• Keep the first test on a desk, not mounted to a moving robot.

First stream

1. Flash a simple ESP32 camera web server example for the exact board.
2. Open serial output and record the IP address.
3. Start at low resolution and verify 30 seconds of stable stream.
4. Move the gimbal slowly by hand and check the ribbon clearance.
5. Take a still frame before adding AI analysis.

Servo and tracking checks

Test pan and tilt separately. Limit angle range first, then increase it after checking the frame. If the image freezes when the servo moves, isolate servo power. If tracking overshoots, slow the movement and add a dead zone around the target center.

Troubleshooting

• Camera init failed: check board profile, camera ribbon direction, PSRAM setting, and pin map.
• Stream freezes: lower frame size, improve WiFi, and test without servos.
• Servo jitters: use separate servo power and confirm common ground.
• Tracking is unstable: improve lighting and test with one high-contrast target.
