Supports power-on auto-start interaction nodes, zero-code required to play with ROS functions, quick to get started.

M260C Smart Speaker (for Plus and Super versions only)
- The M260C smart speaker is equipped with an M260C circular 6-microphone array, noise reduction motherboard, signal adapter board, and sound card speaker. The robot combines radar and camera sensors to easily achieve functions such as voice navigation and intelligent interaction.
1. Sound source localization: smart speakers enable 1-degree precise sound source localization, enabling noise reduction and voice navigation.
2. Voice activation: summon the robot to any location. It identifies the controller’s position via smart speaker and distance via LiDAR.
3. Voice navigation: smart speakers can semantically parse user commands to navigate to any point on a pre-built map.
4. TTS text to audio: this technology enables fully human-computer interaction, supporting expansion of iFlytek’s online voice dialogue function.

Safe Lithium Iron Phosphate Battery with Metal Casing
- Lithium iron phosphate battery is a type of battery that uses lithium iron phosphate as the positive electrode material. Lithium iron phosphate batteries with metal shell protection will not cause dangerous situations such as fire or explosion under high temperature, overcharge and discharge, and external impact. The thermal runaway trigger temperature range of lithium iron phosphate is 530-800°C, which is much larger than the thermal runaway trigger temperature range of ternary lithium batteries, which is 150-200°C. It has the characteristics of high temperature resistance, good stability, and better charging cycle performance, and is a good choice for balancing volume ratio and safety.

Standard Multi-mode Intelligent Control Handle
- The controller supports wired/wireless connections. The wireless communication distance can reach 25 meters, with 15 DIY buttons, 6 channels of analog output, and vibration feedback when remotely controlling the robot, making every operation more realistic. More suitable for robot remote control than model airplane remote control.
