Sensor network MAC protocols are typically configured for an intended deployment scenario once and for all at compile time. This approach, however, leads to suboptimal performance if the network conditions deviate from the expectations. We present ZeroCal, a distributed algorithm that allows nodes to dynamically adapt to variations in traffic volume. Using ZeroCal, each node autonomously config...

A contact-based calibration technique using a robot-mounted calibration probe, has been experimented with. The probe is to be implemented by utilizing a wrist-mounted force sensor. The technique is based on constraining the sampled robot joint poses to those where the probe end is in controlled contact with a planar surface. The paper illustrates how the technique may be used to achieve a joint...

This paper proposes a new approach for calibration of dead reckoning process. Using the well-known UMBmark (University of Michigan Benchmark) is not sufficient for a desirable calibration of dead reckoning. Besides, existing calibration methods usually require explicit measurement of actual motion of the robot. Some recent methods use the smart encoder trailer or long range finder sensors such ...

In this paper, we present an automatic approach for the kinematic calibration of the humanoid robot NAO. The kinematic calibration has a deep impact on the performance of a robot playing soccer, which is walking and kicking, and therefore it is a crucial step prior to a match. So far, the existing calibration methods are time-consuming and error-prone, since they rely on the assistance of human...

We present a novel method for an automatic calibration of modern consumer Timeof-Flight (ToF) cameras. Usually, these sensors come equipped with an integrated color camera. Albeit they deliver acquisitions at high frame rates they usually suffer from incorrect calibration and low accuracy due to multiple error sources. Using information from both cameras together with a simple planar target, we...
