Synchronized Teaching Mode – ESP-NOW

The robotic arm firmware includes built-in support for ESP-NOW, allowing multiple arms to mirror each other's movements in real time.

With this feature, you can set up one-to-one or one-to-many synchronized control without any router, hotspot, or external network.

Simply power on the arms, configure the host and followers, and synchronized teaching works immediately.

What Is ESP-NOW? (Quick Overview)

ESP-NOW is a lightweight, low-latency wireless protocol developed by Espressif. It uses the Wi-Fi physical layer but does not require a Wi-Fi network.

Key advantages:

1. Ultra-low latency — millisecond-level response, ideal for real-time motion sync.
2. No router required — devices communicate directly, even without Internet.
3. Low power consumption — suitable for battery-powered robots.
4. Simple API & reliable performance — stable transmission, long range (up to 100+ meters depending on environment).
5. Flexible networking — supports one-to-one or broadcast (one-to-many).

ESP-NOW Broadcast Synchronization

To get started, you’ll need at least two robotic arms:

• One configured as the Leader (Host)
• Others configured as Followers

After powering on, each arm’s OLED displays:
