Welcome to the introduction to the TRACER MINI mobile robot chassis, a modular and intelligent platform designed for flexible movement on indoor flat surfaces. This guide provides users and developers with a comprehensive overview of the TRACER MINI, detailing its design concepts, features, status indications, electrical interfaces, remote control functionalities, and control instructions for motion.
This section will give a basic introduction to the TRACER MINI mobile robot chassis, so that users and developers can have a basic understanding of the TRACER chassis. As shown in Figure 2.1 and 2.2 below, the overview view of the entire mobile robot chassis is displayed.

Users can determine the state of the car body through the voltmeter, light and buzzer installed on the TRACER MINI. For more information, see Table 2.1.
| Status | Description |
|---|---|
| Current voltage | Power-on rear voltmeter lights up, the current battery voltage can be checked through the voltmeter in the rear electrical panel, accurate to 1v. |
| Low voltage alarm | When the battery voltage is lower than 22V, the car will make a harsh sound of "drop-drop-drop" to prompt. When low battery voltage is detected |
| At 21.5V, TRACER MINI will actively cut off external extended power supply and driver power supply to prevent battery damage. | |
| At this time, the chassis will not be able to carry out motion control and accept external command control. | |
| Buzzer alarm | A sound (DRIP) indicates a low-voltage warning. Two rings indicate that the crash bar is triggered, or the remote control is disconnected. Three sounds represent. |
| Motor overcurrent. Four rings indicate that the drive communication is disconnected. Five-sound low-voltage fault. Six rings indicate an external 12v overcurrent. |
