About DOFBOT

DOFBOT is an Al vision robotic arm with Jetson nano as the main control, Open Source CV as the image process­ing library. mainstream Jupyter Lab as the development tool, and Python3 as the main programming language. The camera is integrated with the robotic arm, and the “2 in 1” design makes the visual recognition of the robotic arm more flexible. It can not only realize color recognition. tracking and grabbing, but also recognize and interact with human body features, and even train garbage classification models for garbage sorting. Through the ROS robot control system, the complex motion control of the 6-DOF serial bus steering gear is simplified. The official provides a guided quick-start tutorial to help you easily control the DOFBOT Al vision robot arm.

PRODUCT FEATURES

Based on I TSOf’J 11\1 O’S powerful Al computing capabilities

NVIDIA Jetson Nano is a small but powerful computer that can run multiple neural networks, object detection, segmentation and speech processing applications at the same time. Equipped with quad-core cortex-A57 processor, 128-core Mazwell GPU and 4GB LPDDR memory, Jetson Nano has sufficient Al computing power, provides 472 GFLOP computing power, and supports a series of popular Al frameworks and algorithms, such as TensorFlow, Pytorch, caffe /caffe2, Keras, MXNET, etc.

Cross-platform interconnection control

Multi-function mobile phone APP (iOS/Android)
A variety of Al gameplays are built-in, and the robot arm can be watched in real time and supports at the same time: gesture interaction, tracking game. garbage sorting, etc.

PC host computer control
In addition to the video screen of the FPV camera, the host computer has also added a 3D simulation model of the robotic arm, which rotates synchronously with the entity, allowing the robotic arm control theory and practice to be combined.

USB handle remote control
In addition to mobile phone APP and computer control, it also comes standard with a USB handle to experience the fun of combining multiple degrees of freedom and multiple keys.

Color recognition interaction

1. Color recognition tracking
   In addition to standard colors, custom colors can also be extracted for color recognition and tracking of the robotic arm, so that the camera can follow the selected color automatically.

2. Catch Game
   In addition to standard colors, custom colors can also be extracted for color recognition and tracking of the robotic arm, so that the camera can follow the selected color automatically.

3. Color capture
   Place the wooden block in front of the camera, and the robotic arm will recognize the color of the wooden block and clamp the wooden block in the corresponding color area to the middle area.

4. Color interaction
   Choose DOFBOT favorite color. It will follow the target color back and forth.

Model training / Garbage sorting

• BASIC FUNCTION: The DOFBOT kit comes standard with multiple wooden blocks with trash patterns. By loading the garbage dassification model, the camera can identify the type of garbage on the wood block and return the garbage name and classification data to the APP. The robotic arm sorts the “garbage” to the corresponding classification area on the map.
• DEVELOPER FUNCTION: You can also identify the area by calibrating the map, place multiple “garbage” blocks in the identification area for real-time recognition, and continuously sort multiple “garbage” to the corresponding classification area on the map.

Human feature recognition and interaction

DOFBOT can recognize human features such as gestures and faces through the camera screen, and complete interactive actions such as grabbing, recognition and tracking.

1. Gesture interaction
   DOFBOT can recognize multiple gestures and perform corresponding actions for interaction.

2. Gesture grab
   Recognize digital gestures, stack the corresponding layers, and finally push down the stacked wooden blocks under the “fist” gesture

3. Face recognition and tracking
   Detect whether there is a face in the current picture, mark the face after it is recognized and follow the movement

ROBOT MOTION CONTROL

1. Robotic arm custom learning action group
   Due to the intelligent serial bus servo, DOFBOT can read and record the angle of each rotation after entering the action learning mode to realize learning and repeat the action group.

2. Fun fixed action group
   There are 8 fixed action groups provided in the APP, you can click the serial number to preview, and click Run to start execution.

3. Synchronous teaching of robotic arm
   This gameplay requires two DOFBOT robots for teaching control Read the joint angle of the servo on the DOFBOT Master Machine side,and transmit it to the Slave Machine side in real time, allowing the Slave Machine to rotate synchronously according to the posture of the Master Machine.

4. 6 degree of freedom inverse kinematics control
   Decompose the servo motion control of the robot arm with 6 degrees of freedom, calculate the theoretical motion angle of each servo by inputting the target coordinates, and simultaneously control the motion of each DOFBOT servo in combination with the servo control protocol.

5. Operating system
   The ROS robot operating system is a collection of tools, software libraries and protocols, designed to simplify the DOFBOT robot platform and build complex and powerful robots.
