High-Efficiency Servo
LeArm AI robotic arm is equipped with high-torque smart digital servos, allowing the robotic arm to grab objects and run smoothly.
Excellent Structure Design
The LeArm AI robotic arm features an all-metal design, equipped with metal brackets and a bearing base, enabling it to achieve flexible rotation.
Inverse Kinematics Algorithm
We provide LeArm AI inverse kinematics analysis to allow users to better understand the working principle of the robotic arm.
Support Sensor Expansion
The Advanced Kit includes sensor modules, enabling creative functions such as AI vision interaction, AI voice control, and multi-sensor applications.
Color Recognition
LeArm AI accurately identifies color blocks within its field of view and uses inverse kinematics to precisely locate and lock onto the target. It then grips the object and places it in the specified area.
Garbage Recycling
LeArm AI leverages deep learning to accurately identify various types of waste cards and can grasp and sort the corresponding objects into designated areas with precision.
Face Recognition
LeArm AI can recognize and store up to three distinct faces. Based on programming, the robotic arm will perform different preset actions for each recognized face.
Tag Recognition
LeArm AI can identify tag blocks within its field of view and precisely grasp and sort them into designated areas.
Voice Control
LeArm AI can "hear" a variety of voice commands from the user and, based on those instructions, will pick up and sort colored blocks accordingly.
Voice Broadcast
With the AI voice interaction module, the LeArm AI can continuously broadcast different voice prompts, delivering seamless audio feedback.
Voice-Controlled Waste Sorting
With the combination of AI voice interaction and vision modules, LeArm AI can flexibly respond to voice commands, automatically identifying and sorting blocks marked with waste cards within its view.
Voice-Controlled Vision Sorting
By integrating the AI voice interaction module and the WonderMV vision module, LeArm AI can automatically identify and sort objects within its field of view based on voice commands from the user.
Sound Control
LeArm AI can detect ambient sounds through a sound sensor and perform corresponding actions, enabling intelligent voice control.
Infrared Control
Equipped with an infrared obstacle avoidance sensor, LeArm AI can detect objects in front of it in real time and automatically perform actions such as grabbing and sorting.
OLED Display
With programmable capabilities, the OLED screen module can display numbers, text, graphics, and more.
Touch Control
Integrated with a high-sensitivity touch sensor, LeArm AI can detect touch status in real time and respond with appropriate actions automatically.
Ultrasonic Ranging
Using an ultrasonic sensor with an LED indicator, LeArm AI can measure the distance to objects ahead, enabling distance-based actions such as grabbing.
Acceleration Control
By continuously collecting data from the accelerometer and analyzing motion direction, LeArm AI can perform different actions accordingly.
