WSAL24019 – UGV01/en

Documentation notice: This technical documentation was independently rewritten from an archived supplier source. Check technical details and commands against the product version and manufacturer documentation before use.

Summary

The UGV01 is a flexible, expandable, off-road capable tracked UGV. It supports multiple hosts (e.g., Raspberry Pi, Jetson Nano, RDK X3) that communicate with the onboard ESP32 slave computer via serial port. The system includes encoder-equipped motors for speed feedback, an onboard multi-function driver board based on ESP32 with WiFi and Bluetooth, a 0.96-inch OLED display, and a UPS power module using 3S 18650 lithium batteries (not included). Two 1020 European standard profile rails allow mounting of external modules.

Technical overview

• The vehicle uses a multi-part independent suspension system to damp uneven terrain; under load while climbing, the suspension compresses and the rear wheels provide additional support.
• Motors are equipped with encoders, enabling speed feedback and closed-loop control.
• The integrated driver board is based on an ESP32 chip and provides interfaces for DC motors, serial bus servos, PWM servos, SD card slots, nine-axis IMU, WiFi, and Bluetooth.
• The device automatically boots into WiFi AP mode with the hotspot “UGV”; the password is “12345678”. The web interface is accessible at IP address 192.168.4.1.
• JSON commands can be sent over serial port, USB, HTTP, or ESP-NOW; most configuration settings can be performed via JSON commands, e.g., connecting to a known WiFi without a USB cable.
• The UPS power module uses three 18650 batteries in series (not included); it features protection circuits against overcharge, over-discharge, overcurrent, and short-circuit.
• Two 1020 European standard profile rails allow mounting external modules such as pan-tilt gimbals or robotic arms.
• All codebases are open source; demo programs run in Arduino IDE without manually configuring the compilation environment.
• The 0.96-inch OLED display shows AP mode, STA status, MAC address, and voltage value at boot.
• If the connection drops during movement, the vehicle automatically stops after a short delay as a safety measure.

Notes and version constraints

• Batteries must be purchased and installed by the customer; reversed polarity can pose an explosion risk – check polarity before charging.
• Firmware update requires disassembling the vehicle to reach the USB connector on the driver board; exact steps depend on the hardware version.
• The stated IP 192.168.4.1 applies only in AP mode; in STA mode the router assigns a dynamic IP.
• The voltage threshold for charging (below approx. 10 V) is not precisely defined according to the source – human confirmation recommended.
• Some command names (CMD_SPEED_CTRL, CMD_PWM_INPUT, CMD_ROS_CTRL, CMD_BASE_FEEDBACK, CMD_WIFI_APSTA) were taken from the table of contents; full parameter lists are missing from the provided text excerpt.
