Online 3-D Trajectory Estimation of a Flying Object from a Monocular Image Sequence for Catching
Catching a fast moving object can be used to describe work across many subfields of robotics, sensing, processing, actuation, and systems design. The reaction time allowed to the entire robot system: sensors, processor and actuators is very short. The sensor system must provide estimates of the object trajectory as early as possible, so that the robot may begin moving to approximately the corre...
متن کاملA Dynamical System Approach for Catching Softly a Flying Object: Theory and Experiment
Catching a fast flying object is particularly challenging as consists of two tasks: it requires extremely precise estimation of the object’s motion and control of the robot motion. Any small imprecision may lead the fingers to close too abruptly and let the object fly away from the hand before closing. We present a strategy to overcome for sensorimotor imprecision by introducing softness in the...
متن کاملTrajectory Estimation of a Flying Object Using High Speed Vision for Catching
This paper presents the current progress on a trajectory estimation of a flying object for a robotic catching system, using general purpose and readily available hardware. A recursive least squares (RLS) algorithm is used to extract and predict the position of a flying object in a 3D environment with the information gathered from only one camera. Fig. 1. 3D tracking and catching task.
متن کاملQuantum controlled-phase-flip gate between a flying optical photon and a Rydberg atomic ensemble
Quantum controlled-phase-flip (CPF) gate between a flying photon qubit and a stationary atomic qubit could allow the linking of distant computational nodes in a quantum network. Here we present a scheme to realize quantum CPF gate between a flying optical photon and an atomic ensemble based on cavity input-output process and Rydberg blockade. When a flying single-photon pulse is reflected off t...
متن کاملCatching a Passing Moment:
This report describes a hitherto-isolated culture in northern Pakistan that has recently under gone rapid exposure to the outside world. Rapid change in Karimabad, a town of 4,600 peo ple in the Hunza Valley, has caused conflicts between cultural inertia and the forces of progress and modernization to surface and produced visible instances of cultural persistence and adap tation. For example...
