Developing a real representation of pose in 2D
In Robotics | No commentThe pose of an object can be considered in two parts, the position of the object and the orientation of the object.

Relative pose in 2D
In Robotics | No commentWe consider multiple objects each with its own coordinate frame. Now we can describe the relationships between the frames and find a vector describing a point with respect to any of these frames. We extend our algebraic notation to ease the manipulation of relative poses.

Relative Positions in 2D
In Robotics | No commentWe introduce the idea of attaching a coordinate frame to an object. We can describe points on the object by constant vectors with respect to the object’s coordinate frame, and then relate those to the points described with respect to a world coordinate frame. We introduce a simple algebraic notation to describe this.

Position and Pose in 2D
In Robotics | No commentTo fully describe an object on the plane we need to not only describe its position, but also which direction it is pointing. This combination is referred to as pose.

2D Geometry Refresher
In Robotics | No commentWe revisit the fundamentals of geometry that you would have learned at school: Euclidean geometry, Cartesian or analytic geometry, coordinate frames, points and vectors.

Introduction to 2D Geometry
In Robotics | No commentWe learn how to describe the position and orientation of objects on a 2-dimensional plane. We introduce the notion of reference frames as a basis for describing the position of objects in two dimensions.

Playing Catch and Juggling with a Humanoid Robot
In Robotics | No commentRobots in entertainment environments typically do not allow for physical interaction and contact with people. However, catching and throwing back objects is one form of physical engagement that still maintains a safe distance between the robot and participants. Using an animatronic humanoid robot, we developed a test bed for a throwing and catching game scenario. We use an external camera system (ASUS Xtion PRO LIVE) to locate balls and a Kalman filter to predict ball destination and timing. The robot’s hand and joint-space are calibrated to the vision coordinate system using a least-squares technique, such that the hand can be…

Synthesizing Object Receiving Motions of Humanoid Robots with Human Motion Database
In Robotics | No commentThis project presents a method for synthesizing motions of a humanoid robot that receives an object from a human, with focus on a natural object passing scenario where the human initiates the passing motion by moving an object toward the robot, which continuously adapts its motion to the observed human motion in realtime. In this scenario, the robot not only has to recognize and adapt to the human action but also has to synthesize its motion quickly so that the human does not have to wait holding an object. We solve these issues by using a human motion database obtained…
