Enable a robot to infer the type of joint between moving clusters of 3d features. This can further be used to build a kinematic structure of an observed object.

The interest in robots that are able to act in unstructured environments is increasing.
Allow Robots to grasp unknown objects while perceive the environment and the objects with a 3D sensors.
Interactively explore and grasp real-world objects using visual feedback.
In this thesis, we study the topic of Lifelong Robotic Object Perception. We propose, as a long-term goal, a framework to recognize known objects and to discover unknown objects in the environment as the robot operates, for as long as the robot operates. We build the foundations for Lifelong Robotic Object Perception by focusing our study on the two critical components of this framework: 1) how to recognize and register known objects for robotic manipulation, and 2) how to automatically discover novel objects in the environment so that we can recognize them in the future.
The thesis describes a novel approach to recognizing objects in RGB-D images and for making this information persistent in a 3D semantic map. It makes two major contributions: Firstly, he proposes a novel approach to object-class segmentation in RGB-D images based on random forest classifiers that provides a pixel-wise class labeling in the image.
Every planning problem in robotics involves constraints. Whether the robot must avoid collision or joint limits, there are always states that are not permissible.Some constraints are straightforward to satisfy while others can be so stringent that feasible states are very difficult to find. What makes planning with constraints challenging is that, for many constraints, it is impossible or impractical to provide the planning algorithm with the allowed states explicitly; it must discover these states as it plans. The goal of this thesis is to develop a framework for representing and exploring feasible states in the context of manipulation planning.
