The Effect of Target Position and Tactual Recognition Field Size on Touch Bias and Accuracy
… cause the operator to touch slightly below the target. The amount of touch bias created from this misjudgment fluctuates according to the target's position on the screen. Additionally, the percentage of touches that activate a specific target varies according to the size of the tactual …

Gaze control for remote robotics
… are investigated. The merits of a hybrid position control method which blends the current location of a robot with the target position in order to attract the robot towards it are evaluated. This system is built on by adding haptic virtual fixtures which guide the operator towards the …

The effects of extended practice on the control of coincident timing tasks
… precise moment that the sweep hand reached a "target position" (250, 500, and 1000 msec). All subjects were given 100 trials of practice at a particular "target position" on each of four consecutive days. Schmidt's (1972) index of preprogramming was calculated for each subject each day in order …

Search for a Moving Target
… model of a discrete sequential search for a target moving in discrete space is given. The model is based on a Bayesian updating algorithm giving successive probability distributions of target position at intervals throughout the search. Updating allows for target movement and for negative …

Multiple Target Tracking in Experimental Multistatic MIMO mmWave Radar Sensor Networks
Location awareness of non-collaborative targets within 5G and beyond systems is becoming ever more prominent. This paper presents a passive, hardware-agnostic multiple target tracking (MTT) system that addresses the shortcomings in current wireless position technology and is capable of seamlessly …

Voice Control of Fetch Robot Using Amazon Alexa
… desired direction as well as track and follow a target object. The follow model was also learned by Neural Network training, which allows for the target position to be predicted in future maps.

On line tracking of moving objects from moving platforms
It is desired to position the end point of a conveyor belt, which carries material removed by a moving pavement trimmer, above the bed of a moving dump truck. The present report describes the analytical design and practical control of a tracking system for positioning the conveyor. Initial tests …

Non-linear digital control of a McKibben muscle system
… from Flock-of-Birds sensor to achieve a desired position. The results show the expected instability of the bang-bang controller, and confirm the superiority of the non-linear proportional method in achieving rapid and smooth movement of the joint from one target position to the next.

Cognitive conflict in learning three-dimensional space station structures
… but slightly lower in FC than in GC. The target position relative to the subject's body did not affect performance, but subjects responded significantly faster when they were visually upright than when they were upside-down. Although alternative explanations cannot be ruled out, data …

Safe and reliable dynamic coverage control for multi-agent systems
… swarming control where a leader agent selects a target position that is in an uncovered region while all other agents are commanded to swarm around the leader agent's target position. In this scheme, coverage and swarming control inputs are also decoupled, meaning that only one of them is active …

SHEDDING NEW LIGHT ON OLD DATA: FINDING NEW RESULTS FOR EXOPLANET SCIENCE IN ARCHIVAL DATA
… signal in the detector to subpixel shifts in the target position over time. By creating a pipeline to process all targets, regardless of observing strategy, systematics are dealt with uniformly and different planets’ spectra can be meaningfully compared. I show that the height of the water feature …

Algorithm design for smart vision sensors.
… and can be implemented to find the 2-dimensional position of a target. In particular, the problem of finding the deviations along both X and Y directions is formulated as a matching process between the saved template, which represents the reference position, and the picture of a real static target …

Deformable Object Manipulation with a Tactile Reactive Gripper
… (1) LQR with the GP model linearized about the target position and (2) time-varying LQR with the GP model linearized about the current state and (3) model predictive control with the full dynamics model and constraints on the state and input of our system over a finite horizon. We extend our …

The Impact of Type 2 Diabetes and Associated Diabetic Peripheral Neuropathy on Grip Force Control and Hand Function
… subjects attempted to actively reproduce a target position between the index finger and thumb without visual feedback over two consecutive days. Nineteen subjects performed the same procedure, but in a one-day setting and under two conditions: With and without vibration applied to the dorsal …

Kinematic Modeling and Dynamic Aspects of an Accelerating Quadruped
… as well as the angular rates required for these target manifolds. The parameterised inverse kinematics models were also able to generate smooth task space trajectories to within acceptable tolerances of the target position and for a single, full gait the corresponding joint space trajectories …

RattleSnake : stochastic folding for chain programmable matter
… and rectifies it to produce motion towards the target position. We propose two variants of this system: 1) smart clutches that can be reprogrammed in situ and fold through arbitrary paths in configuration space and 2) ratchets that are programmed ahead of time and are entirely passive. We …

Non-Field-of-View Acoustic Target Estimation
… of sound signal information to localize target position through auditory sensors combination with other sensors within grid-based recursive estimation structure for tracking using nonlinear and non-Gaussian observations. Three approaches to NFOV target localization are investigated. These …

PREDICTION OF RESPIRATORY MOTION
… Thoracic and abdominal tumors may change their positions during respiration by as much as three centimeters during radiation treatment. The prediction of respiratory motion has become an important research area because respiratory motion severely affects precise radiation dose delivery. This …

A Bayesian Framework for Multi-Stage Robot, Map and Target Localization
