PuppyPi HiWonder Quadruped Robot

with AI Vision Powered by Raspberry Pi ROS Open Source Robot Dog

Powered by Raspberry Pi 4B 4GB, PuppyPi is an AI vision quadruped robot. It is made of aluminium alloy and loaded with 8 powerful coreless servos. Linkage mechanism on its leg attributes to flexible and diverse actions and enables it to walk, step up and down stair, etc. It owns first person view for realizing more interesting AI games, including target tracking, face detection, line following, auto climbing and so on.
PuppyPi is based on ROS (robot operating system) and supports Gazebo simulation. It serves as a great platform for you to learn and verify machine vision, robot kinematics, quadruped gait controlling and other algorithms. Besides, ample tutorials and open-source codes will help you quickly get started! 

 

Realistic Bionic Appearance

Linkage Mechanism, Efficient Movement PuppyPi's legs employ a linkage mechanism to increase the angular velocity of its lower legs. The independent movement of different parts of the leg contributes to a greater rotation range.

Aluminium Alloy Body with Perfect Structure Made of aluminium alloy and equipped with metal bearings on joints, PuppyPi features light weight and high strength. Compact and flexible body lets it show talents even on the desk.

 

Gait Planning, Free Adjustment

Walk, Amble and Trot gaits can be realized through adjusting touchdown time, lift time and lifted height of each leg as well as the speed of switching front legs and hind legs.

 

Inverse Kinematics, Linkage Mechanism

Through inputting the coordinate of the end of the leg into the visual PC software, the servo angle can be calculated by its inner processor so as to design cool actions.

 

Speed, Height and Inclination Adjustment

PuppyPi's its height and inclination can also be adjusted to make it turn as walking.

 

Intelligent Self-balancing

The built-in IMU sensor can monitor PuppyPi's posture in real-time to adjust its joints to balance the body.

 

AI Vision, Unlimited Creativity

With built-in HD wide-angle camera of 100W pixel, PuppyPi is capable of recognizing and locating different targets to realize line following, crossing obstacle, face detection, ball shooting, color tracking, tag recognition and other creative AI games.

Line Following Via OpenCV, PuppyPi is able to recognize black and red line, and then calculate the location of the line so as to adjust the walking gait and realize line following.	Crossing Obstacle PuppyPi can recognize the location of the stair to adjust its posture and action as well as switch the gait so as to complete crossing obstacle.
	Face Detection PuppyPi utilizes OpenCV to load the trained models of face detection. When recognizing human face, it will interact with you.
Color Tracking Recognize the position of the ball, and continuously adjust its posture to track it.	Ball Shooting Locate the ball via OpenCV, track it in real-time with PID algorithm, and then switch the gait to shoot the ball.
Tag Recognition Recognize AprilTag and give different reactions according to different tags.

Support APP Control, FPV Image Feedback

Android and iOS mobile APP are available. Via the APP, you can remotely control the robot and view what the robot sees.

First Person View, HD Transmitted Image The HD camera will transmit the FPV image to the APP bringing you realistic experience.

Flexible Vision Guided, Wide Angle Perception Via the APP, PuppyPi can be controlled at your fingertips.

Quickly Start AI Games Only one click to switch the various AI games, including color recognition, target tracking, etc.

Carry Lidar for SLAM Mapping and Navigation

PuppyPi can carry a TOF Lidar on its back to scan the surroundings 360 degrees to realize advanced SLAM functions, including localization, mapping and navigation, path planning, dynamic obstacle avoidance, etc. And the combination of Lidar and PuppyPi can bring more interesting AI games, such as Lidar tracking and Lidar guarding.

Lidar Mapping and Navigation Lidar adopts Gmapping, Hector and Karto algorithms to map, and can implement single-point navigation, multi-point navigation and TEB path planning.
				Multi-point Navigation TOF Lidar is able to detect the surroundings in real time, so it can plan the path in real time to let PuppyPi Pro avoid the obstacle when executing multi-point navigation.
Lidar Guarding PuppyPi employs TOF Lidar to scan the protected area. When detecting someone trespassing, it will turn to the intruder and sound the alarm.			Lidar Tracking PuppyPi can work with Lidar to scan the moving target ahead, and follow behind it.

 

Support Sensor Expansion, Create More Functions

PuppyPi is compatible with MP3 module, touch sensor, dot matrix display, ultrasonic sensor and other modules making it possible to build more creative AI projects.

Obstacle Avoidance Combining with ultrasonic sensor, PuppyPi can range the distance of the obstacle ahead.

Dot Matrix Display Working with dot matrix module, PuppyPi can display the shape and color of the recognized objects.

 

ROS Robot Operating System

Global Popular Robotic Communication Framework

ROS is an open-source meta operating system for robots. It provides some basic services, such as hardware abstraction, low-level device control, implementation of commonly used functionality, message-passing between processes, and package management. And it also offers the tools and library functions needed to obtain, compile, write, and run code across computers. It aims at providing code reuse support for robotics research and development.

Support Gazebo Simulation

PuppyPi adopts ROS framework and supports Gazebo simulation. Gazebo brings a fresh approach for you to control PuppyPi and verify the algorithm in simulated environment, which reduces experimental requirements and improves efficiency.
