3D Object Sorting

Equipped with a 3D depth camera, ArmPi Ultra detects objects of various shapes within its field of view. Combined with ChatGPT, it understands user instructions and performs the required sorting actions.

AI Embodied Intelligence Applications

Powered by high-performance hardware and multimodal large model, ArmPi Ultra can perceive and understand the environment, plan actions, and perform tasks with flexibility. It enables advanced human–robot collaboration and intelligent task handling, delivering a more natural and efficient interactive experience.

Real-Time Detection

Powered by ChatGPT, ArmPi Ultra understands user commands and analyzes scenes in real time. It provides instant feedback on image content and object features through both text and voice.

Vision Tracking

By combining ChatGPT with OpenRouter's visual large model, ArmPi Ultra interprets user commands to identify and locate objects. With inverse kinematics algorithms, it achieves precise and responsive target tracking.

Intelligent Transport

With the support of the Vision AI large model, ArmPi Ultra identifies target objects and retrieves their positional data. Combined with ChatGPT, it interprets user commands to transport objects to designated locations.

Smart Home Assistant

Powered by a multimodal large model, ArmPi Ultra recognizes and analyzes objects in its environment. Paired with ChatGPT, it understands user instructions and provides appropriate responses through both speech and actions.

Deep Learning Model Training

Custom object-detection models can be trained and deployed using suitable supported hardware and software. Hardware-specific acceleration requires a compatible deployment environment; no onboard NVIDIA GPU is included.

Waste Sorting

ArmPi Ultra robotic arm kit is equipped with garbage pattern blocks. By loading the corresponding model, ArmPi Ultra can quickly recognize different garbage and place it in the corresponding classification area.

Item Sorting

By training models of daily items and generating corresponding models, with the support of depth cameras, ArmPi Ultra can quickly recognize and grab corresponding items by obtaining the depth information of the items.

Gazebo Simulation

The ArmPi Ultra robotic arm is developed using the ROS framework and supports GAZEBO simulation. The robotic arm is controlled and algorithm verified in a virtual environment, which reduces the requirements for the experimental environment and improves experimental efficiency.

Applications

Develop color-sorting exercises,vision tracking,depth-guided pick-and-place and simulated manipulation experiments. Use depth-equipped kits for3D spatial tasks and Advanced hardware for voice-box activities. Network AI services require compatible accounts,connectivity and software configuration.
