Waveshare RaspRover: AI-Powered 4WD Robot With Computer Vision, In-Build Pan-Tilt Module Suitable for Raspberry Pi 4B / Raspberry Pi 5 - RS7334

Description:

The RaspRover is an open-source 4WD AI robot designed for exploration and creation and adopts the dual-controller structure design. The host controller adopts Raspberry Pi 4B / Raspberry Pi 5 for AI vision and strategy planning, and the sub-controller uses ESP32 for motor PID control, IMU sensor control, OLED screen control, servo control, LED on/off control, etc. effectively saving computing and IO resources for the host controller.

Adopts 2mm thickness all-aluminum metal body, durable and reliable. The chassis is equipped with soft anti-skid rubber tires with 4x N20 encoder motors, supports closed-loop speed control, provides excellent shock-absorbing performance, and the maximum speed is up to 0.65m/s. Built-in 3S lithium UPS power supply module (the batteries are NOT included) can provide powerful and lasting power, support charging, and discharging at the same time to ensure continuous standby time.

Comes with a CSI camera for the Raspberry Pi 4B version and a USB camera for the Raspberry Pi 5 version, Which supports real-time transmission of high-frame-rate video. No App installation is required, allowing users to connect and control the robot via mobile phones, tablets, and computers via a browser Web App, and obtain- real-time information feedback. Users can enjoy a smooth visual experience and can capture different wonderful moments through functions such as taking photos and videos. In addition, the robot's various information feedbacks - including battery voltage, CPU usage, etc. - are displayed in real-time through the WEB application, allowing users to monitor the robot's status in real-time.

The PT version is equipped with a 2-DOF high-torque flexible pan-tilt and a 5MP 160° wide-angle camera for various AI robot vision functions. With high-brightness LED light for ensuring clear images in low-light conditions. Also equipped with a tactical rail to easily install peripherals for more functions.

Note: Raspberry Pi 4, and Pi 5 are not included you need to buy them separately

based on OpenCV to achieve Face recognition, supports automatic photo taking or video recording once a face is recognized

Pin Description:

Multi-Functional driver board

• Used as the sub-controller of the robot, the onboard ESP32 module can be controlled via serial port, HTTP request, ESP-NOW, and other communication protocols, providing a web application for some basic control of the robot.
• ESP32 can handle low-level computations for the robot, such as a high-frequency PID controller for controlling wheel speed, high-frequency inverse kinematics calculations for robotic arm linkages, position interpolation calculation, Pan-Tilt angle control OLED screen control, etc.
• ESP32 is also responsible for data reading of various sensors, such as IMU (9-axis attitude sensor) and INA219 (battery voltage detection), and can independently achieve the camera vertical stabilization function, effectively saving computing and IO resources for the host controller.

Audio Driver Board

• The audio driver board is designed for the robot host controller, and onboard USB interface, suitable for Raspberry Pi 4B / Raspberry Pi 5 and other motherboards, and multi-system compatible.
• Adopts SSS1629A5 audio control chip, provides reliable audio input and output functions, supports USB interface communication, driver-free, plug and play. Onboard APA2068 audio amplifier chip, provides high-quality audio amplification to ensure clear and stable audio signal output.
• Integrated FE1.1S USB 2.0 HUB and CH340 chips for sending data from serial peripherals such as Lidar to the host controller via USB cable without occupying too many resources of the host.
