—This paper summarizes lessons learned from the first Amazon Picking Challenge in which 26 international teams designed robotic systems that competed to retrieve items from warehouse shelves. This task is currently performed by human workers, and there is hope that robots can someday help increase efficiency and throughput while lowering cost. We report on(More)
Stroke rehabilitation is labor-intensive and time-consuming. To assist patients and therapists alike, we propose a wearable system that measures orientation and corrects arm posture using vibrotactile actuators. The system evaluates user posture with respect to a reference and gives feedback in the form of vibration patterns. Users correct their arm(More)
Posture measurement and correction using inertia sensors are finding applications in rehabilitation as well as in human robot interaction systems. This paper presents two designs of arm posture mapping and replication system using inertia sensors and vibrotactile feedback device. The designs differ in the number of vibrotactile actuators and the vibration(More)
A systematic review was carried out to examine the use of robots in early childhood and lower level education. The paper synthesizes the findings of research studies carried out in the last ten years and looks at the influence of robots on children and education. Four major factors are examined – the type of studies conducted, the influence of robots on(More)
In sports training and exercises, the velocity and position of the person is very important for motion evaluation. Despite of the development in motion capturing, a proper method for velocity monitoring for daily use is still not elaborated. In this work, a velocity tracking and localization method using only three IMU sensors is introduced. In the method,(More)
This paper presents an automated fish fry counting by detecting the pixel area occupied by each fish silhouette using image processing. A photo of the fish fry in a specially designed container undergoes binarization and edge detection. For every image frame, the total fish count is the sum of the area inside every contour. Then the average number of fishes(More)
This paper presents an integrated system for upper limb rehabilitation which uses small inertia-based sensors and vibrotactile feedback devices. Vibrotactile feedback is incorporated together with two Inertial Measurement Units (IMUs) attached at the upper arm and the forearm to measure arm motions. The whole arm posture is modeled using three parameters -(More)
When appropriate sensing and feedback are utilized, automation could be used in occupational therapy to aid patient rehabilitation. Previous studies have shown the feasibility of a system that uses inertial measurement units (IMUs) for sensing and vibrotactile feedback for correction. In this paper, we present a similar system with a reconfigured(More)
For rehabilitation applications using multiple types of feedback can help speed up posture correction of the subject - visual cues are particularly helpful in providing global information to the subjects. This paper presents a system that aids students to mimic a master's arm posture using vibrotactile feedback and visual cues. The design of the(More)
