The robot control two dynamixel motors via ROS and OpenCR. For providing a easy way of robot control, we built a driving control package name easyGo. See Control Package Page.

Mapping should be preceded before deploying robots. See SLAM Page.

Using pcd map, the robot can plan global path using our FMM based modified A*. See GPP Page.

The robot can follow the generated path by motion planner. Our motion planner is using our real-time ground segmentation method named MORP. See Motion Planning (MORP) Page.

RGB-D localization, global path planning and motion planning are integrated in one python script. Just run integration.py. For details, see Integration Page

See Human-Computer Interaction Page.

DPoom is also availble in ROS Gazebo simulation with equivalent codes. To simulate DPoom in Gazebo: DPoom_gazebo

Our navigation method can be simulated in Gazebo. Current state-of-the-art navigation approches based on DRL (CADRL, LSTM-RL, SARL) are available with DPoom platform. To evalute navigation performance with DPoom in Gazebo: Gazebo-CrowdNav

These days mobile robots are rapidly developing in the industry. However, there are still some problems for practical application such as expensive hardware and high power consumption. In this study, we propose a navigation system, which can be operated on a low-end computer with an RGB-D camera, and a mobile robot platform to operate integrated autonomous driving system. The proposed system does not require LiDARS or GPUs. Our raw depth image ground segmentation extracts a traversability map for safe driving of the low-body mobile robots. It is designed to guarantee real-time performance on a low-cost commercial single board computer with integrated SLAM, global path planning, and motion planning. Running sensor data processing and other autonomous driving functions simultaneously, our navigation method performs fast at 18Hz refresh rate for control command, while the others have slower refresh rates. Our method outperforms current state-of-the-art navigation approaches as shown in 3D simulation tests. In addition, we demonstrate the applicability of our mobile robot system by successfully autonomous driving in a residential lobby.
