Robot Bin-Picking Based on Deep Learning and 3D Pose Estimation

This thesis presents a deep learning based object recognition and point cloud segmentation design for bin-picking. The deep learning design for point cloud segmentation is used to increase the efficiency of object recognition and reduce the computational efforts of pose estimation. A RealSense SR300 RGB-D camera is utilized to acquire the RGB images and depth images. RGB images are used by Deep Neural Network (DNN) object detector and the depth images are applied to generate point cloud of workpieces. When the object is recognized in the RGB images, it will be located by a bounding box. We propose a 3D-To-2D projection and index filtering scheme to segment the corresponding point cloud according to the bounding box. Then, a voting-scheme is employed to the segmented object point cloud to obtain coarse pose of the object. Then the pose clustering and iterative closest point (ICP) algorithms are used to refined the pose estimation. The estimated object pose data are sent to the robot controller for picking the object. Practical experiments on TM5 robot arm show that the average pose estimation time is less than 1.2 seconds, the average picking cycle time is less than 15 seconds and the picking success rate achieves 92.5%.

  • Collision-free Motion Planning for Human-Robot Collaborative Safety under Cartesian Constraints

    This thesis presents a real-time motion planning and control design of a robot arm for human-robot collaborative safety. Multiple KinectV2 depth camera are utilized to model and track dynamic obstacles (e.g. Humans and objects) inside the robot workspace. Depth images are applied to generate the point cloud of segmented objects in the environment. A K-nearest neighbor (KNN) searching algorithm is used to cluster and find the closest point from the obstacle point cloud to the robot. Then, a Kalman filter is applied to estimate the obstacle position and velocity. For the collision avoidance behavior, the repulsive force is generated for the robot end effector by calculating the minimum distance between the robot and moving obstacles. Moreover, a novel collision-free motion planning method is proposed not only to keep robot body from colliding with objects but also to preserve the execution of robot’s original task under the Cartesian constraint of the environment. Practical experiments show that the 6-DOF robot arm can effectively avoid obstacles in a constrained environment and complete the original task.

    Voice Remote Control Design of a Mobile Robot Using Shared-Control Approach

    Human voice provides a convenient and natural way to communicate with a service robot. It is desirable to operate a mobile robot using voice commands. However, in practice, simple voice commands are not sufficient to give continuous and safe motion of a mobile robot in a complex environment. This work studies a shared-control approach to remote control of a mobile robot. A remote control scheme for an omnidirectional mobile robot is proposed to overcome the delay-time problem of voice commands and maintain the safe motion of the robot using simple voice commands. In this work, we combine the robot autonomy and human intention by using shared-control techniques. The human and robot interactive gains are obtained by computing posterior of free-space using a Bayesian recursive algorithm. Experimental results are presented to demonstrate the effectiveness of the proposed method.

    Design and Implementation of an Attitude Controller for an Octocopter Using Fuzzy+PID

    The objective of this work is to design and implement attitude control for an octocopter. Octocopter is one of the Unmanned Aerial Vehicles (UAVs), which have grown fast recently, and various applications have been developed. In this work, the dynamic model of an octocopter is obtained by making the configuration similar to a quadcopter. In order to stabilize the attitude control of the octocopter, we proposed a Fuzzy+PID design of the attitude controller. Both computer simulation and real-time experiments have been carried out by using LabVIEW programming. In the simulation, we investigated the performance of the proposed Fuzzy+PID controller and tuned the controller parameters. For real-time control, NI-MyRio has been chosen to implement the controller onboard the octocopter. The practical experiments show that the proposed Fuzzy+PID controllers can handle the disturbances during flying and have robustness against certain environmental conditions. The experimental results validate the simulations and verify the effectiveness of the developed controller.

    Compliant Motion Control of a Walk-Assistant Robot Based on Force and Gait Information

    This thesis presents a new method to provide compliant motion of a walk assistant robot based on user status and motion intent. A laser scanner is used to detect the user's gait information and a force/torque sensor detects desired motion direction. The compliance controls will provide the walking assistance. The robot velocity is regulated by user gait information and the robot motion direction is adjusted by force/torque sensor information. These two compliant controllers allow the walking assist robot to generate passive behavior and provide walking assistance effectively.

    Shared-Controller Design for an Omnidirectional Interactive Robot

    It is usually difficult to remotely control of a mobile robot using only an onboard camera. The robot can easily bump into an obstacle due to limited view angle of the on-site scene. The thesis presents a shared-control architecture for effective remote control an omnidirectional mobile platform. The platform is able to move in any direction without changing robot’s heading, such that a stable camera scene is available for remote control. A user interface is designed to use smart phone/tablet to remote control the robot by the interactive touch screen. The proposed controller determines the human and robot interactive gains by computing user’s confidence factor.

    CAD-Based Pose Estimation for Random Bin-Picking of Multiple Objects

    In this thesis, we propose a CAD-based 6-DOF pose estimation design for random bin-picking of multiple objects using a Kinect RGB-D sensor. A voting-scheme was adopted for 6-DOF pose estimation as well as recognition of a set of 6-DOF poses of different types of objects in the bin. We combine 3D CAD model of objects with a virtual camera to generate point cloud database for pose estimation. A design based on voxel grid filter is suggested to decrease the number of 3D point cloud of object for reducing time of pose estimation. Furthermore, we use an outlier filter to filter out bad matching poses and occluded ones.

    Probability-Based Pose Planning for Mobile Manipulation

    In this thesis, a system is designed and experimented for efficient mobile manipulation of a dual-arm robot. Because of limited workspace of the robot arm, robot grasping may fail if the target object is outside the workspace. At the same time, navigation errors also affect the grasping as the robot needs to move toward the target object. In this thesis, we construct a graspability map to describe the possibility of successful grasping inside workspace of the robot arm and we also construct a reachability map to describe the feasibility the robot can navigate to the target. These two maps are integrated to determine the robot location for grasping the target object.

    Instrument Contact Force Estimation Using a 3D Reconstruction Model

    This thesis aims to develop a method to estimate contact force for minimally invasive surgery (MIS) by using image processing and 3D reconstruction modeling. In order to provide surgeons a feeling of contact force between human tissue and instrument, we develop a method to calculate tissue deformation by reconstructing 3D model and estimate force information. The force information will be feed-back to a haptic device to allow a surgeon feel contact force. In this thesis, we propose a 3D model reconstruction method to calculate tissue surface under deformation, and use the deformation data to obtain contact force near the instrument tip.
