Wireless Glove Control
Control Hiwonder robotic arm in real time using the wireless glove. With programmable responses, the arm can perform various actions based on your movements.
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. LeArm AI 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" and "understand" a variety of voice commands from users and accordingly pick up and sort colored blocks.
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
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 users.
Voice-Controlled Vision Sorting
