Product Introduction
AiNex standard is an intelligent humanoid robot built on the Robot Operating System (ROS). It boasts 24 degrees of freedom (DOF) and is powered by a Raspberry Pi. With self-stabilizing inverse kinematics, AiNex excels in walking, climbing, hurdling, grasping, and performing complex movements. Furthermore, its height, turning radius, and speed can be adjusted!
Equipped with a 2DOF AI vision camera and robotic hands that can open or close, AiNex can accomplish tasks like line following, target tracking, ball shooting, intelligent picking and sorting, transportation, stair climbing, and more, using AI vision and advanced kinematics. We offer comprehensive ROS source code and detailed tutorials to bring your AI scenarios to life.
1) 2 DOF HD Wide-angle Camera
The head of AiNex is equipped with a 120° high-definition wide-angle camera, which can effectively identify and locate target objects by utilizing OpenCV image processing.
2) Powered by Raspberry Pi
AiNex is controlled by a Raspberry Pi and is equipped with intelligent high-voltage bus servos. It is programmed in Python and can complete a variety of AI intelligent applications such as color tracking and face detection.
3) Movable Hand Anti-blocking Protection
AiNex standard can be expanded by mechanical hands, which can flexibly grab and carry small items. The hand servos provide angle and temperature feedback, effectively preventing damage caused by obstructions.
4) Dual Hip Joints Original Structure
AiNex is equipped with two hip joints to support the rotation of the legs on the Z-axis, making the robot more flexible in turning. The hip joint is equipped with a magnetic encoder bus servo, which provides high accuracy and stability.
5) 24 DOF Aluminium Alloy Structure
AiNex standard is constructed from aluminum alloy and features up to 24 degrees of freedom (DOF), empowering the robot to execute a wide range of actions and ensuring its flexibility in movement.
6) X, Y, Z Axis Coincident Design
AiNex is equipped with two hip joints to support the rotation of the legs on the X-axis,Y-axis and Z-axis,making the robot more flexible in turning. The structural design incorporates overlapping X-axis,Y-axis and Z-axis, ensuring orthogonal alignment. This integration not only enhances AiNex's bionic qualities but also significantly improves the robot's flexibility in movement.
7) Gait Planning Free Adjustment
① Self-stabilizing Gait Algorithm
AiNex's body incorporates a semi-closed-loop self-stabilizing gait algorithm. This algorithm enables real-time dynamic adjustments to the robot's gait.
② Adjustable Height, Speed, Direction and Turning Radius
AiNex's height, speed, and turning radius are easily adjusted, allowing it to execute turns while walking.
③ Provide Inverse Kinematics Function & Debugging Software
We offer comprehensive biped kinematics analysis, ROS-based inverse kinematics functions, and parameter debugging software to reduce project development timelines.
8) Vision Recognition Target Tracking
AiNex uses Opencv as image processing library to identify target items and complete Al games such as color recognition, color tracking, face detection and apriltag recognition.
① Color Recognition and Tracking
AiNex utilizes OpenCV to process image for recognizing and locating the color. When it detects the color red, AiNex nods. Upon detecting green or blue, the robot will shake its head. Moreover, it can track the movement of the target color using PID algorithm.
② Face Detection
AiNex loads a pre-trained face detection model using OpenCV and performs a greeting action when recognizing a human face.
③ AprilTag Recognition
AiNex can identify AprilTags and respond with various actions based on the recognition outcome. The robot kit comes with AprilTags, allowing you to program customized reactions corresponding to each tag.
④ Autonomous PID Line Following
By utilizing the PID algorithm for computation and employing camera-based recognition, AiNex can change its gait to successfully follow the line.
⑤ Auto Shooting
AiNex can calculate the distance to the target by determining its coordinates. Subsequently, it autonomously adjusts its gait to accomplish ball shooting.
9) MediaPipe Development Upgraded Al lnteraction
Developed upon MediaPip ealgorithm, AiNex can identify humanbody features to enable functions like face detection, gesture recognition, and human body recognition among others.
10) Somatosensory Control
AiNex can execute appropriate actions upon recognizing the human body.
11) Fingertip Trajectory Control
Based on the detection of the distance between fingertips AiNex can adjustits height accordingly.
12) Upgraded Gait Algorithm,Revolutionary Breakthrough
① Autonomous PID Line Following
② Low Clearance Passage
③ Up and Down Steps
④ Autonomous Hurdling
13) Movable Hand Flexible Picking
AiNex standard can be expanded by mechanical hands which can flexibly grab and carry small items catering to wider range of Al creative scenarios.
① Ingenious Design & Anti-blocking Protection
The hands are capable of fully opening up to 72mm wide for easy handling of small objects. The hand servos provide angle and temperature feedback, effectively preventing damage caused by obstructions.
② AI Recognition & Smart Sorting
The camera positioned at AiNex's head can identify and pinpoint target-colored blocks, enabling it to pick up and sort these objects.
③ Autonomous Grabbing & Object Transportation
Using vision, it can calculate the distance to objects and, depending on the distance, automatically adjust its gait to transport the objects to the designated position.
14) App Control (iOS/ Android)
The app is compatible with both iOS and Android systems, offering a wide rangeof Al games and live first-person-view camera feeds.
