Architecture and Software Design for a Service Robot in an Elderly-Care Scenario

Systems for ambient assisted living(AAL) that integrate service robots with sensor networks and user monitoring can help elderly people with their daily activities, allowing them to stay in their homes and live active lives for as long as possible. In this paper, we outline the AAL system currently developed in the European project Robot-Era, and describe the engineering aspects and the serviceoriented software architecture of the domestic robot, a service robot with advanced manipulation capabilities. Based on the robot operating system(ROS) middleware, our software integrates a large set of advanced algorithms for navigation, perception, and manipulation. In tests with real end users, the performance and acceptability of the platform are evaluated.

Development of a Haptic Interface with Proximity Sensors and Vibration Motors

As described in this paper, we propose a new haptic interface for a service robot. For safety with service robots working in a space where people live, some notification before collision with an obstacle is desirable. To achieve such a function, we developed a master-slave manipulator system in which the slave manipulator surface is covered with many proximity sensors. Additionally, we developed a haptic device that feeds back proximity sense information to the operator using small vibration motors. We attached the haptic device to the arm of the operator and vibrated the vibration motor corresponding to the sensor. Thereby, the operator was able to ascertain the position of an object near the manipulator, and to make the robot maneuver to avoid it before collision. To confirm the system usefulness, we equipped subjects with the developed proximity sense presentation device and performed a detection-position-specific experiment and an obstacle avoidance experiment in a narrow space. As results of the detection position specific experiment on five subjects, four subjects reported the detection position correctly. The remaining one person failed because of his particular arm shape. Operation experiments conducted in a narrow space showed that all subjects＇ work was successful when given feedback of proximity sense information. Nobody was successful without proximity sense information. Results of these two experiments demonstrate that this proposed system is useful for obstacle avoidance of a master-slave manipulator system.

Support for Independent Work： Use of Cell Phones by the Intellectually Disabled in Their Daily Lives

This paper presents a technological solution to promote and help independent access to work for disabled people. The aim is to develop a form of technical assistance that supports them in the control of schedules, prevention of dangerous areas in the work place, warnings and automatic alarm generation. The device chosen to exchange all this information is a smartphone based on Android Operating System and GPS （Global Positioning System） technology mainly. A set of Android applications has been developed using Java language, and controlling the device via Google-developed Java libraries. All of them are connected to the Server Application through the Communications Module. The Server Application Module provides the assistants or psychologists the possibility of supervise all the handicapped people activities. The assistants, psychologists and users have all evaluated the application very positively as it covers disabled people＇s needs perfectly.

Personalizing a Service Robot by Learning Human Habits from Behavioral Footprints

For a domestic personal robot, personalized services are as important as predesigned tasks, because the robot needs to adjust the home state based on the operator's habits. An operator's habits are composed of cues, behaviors, and rewards. This article introduces behavioral footprints to describe the operator's behaviors in a house, and applies the inverse reinforcement learning technique to extract the operator's habits, represented by a reward function. We implemented the proposed approach with a mobile robot on indoor temperature adjustment, and compared this approach with a baseline method that recorded all the cues and behaviors of the operator. The result shows that the proposed approach allows the robot to reveal the operator's habits accurately and adjust the environment state accordingly.

Finding misplaced items using a mobile robot in a smart home environment

Smart homes can provide complementary information to assist home service robots.We present a robotic misplaced item finding(MIF)system,which uses human historical trajectory data obtained in a smart home environment.First,a multi-sensor fusion method is developed to localize and track a resident.Second,a path-planning method is developed to generate the robot movement plan,which considers the knowledge of the human historical trajectory.Third,a real-time object detector based on a convolutional neural network is applied to detect the misplaced item.We present MIF experiments in a smart home testbed and the experimental results verify the accuracy and efficiency of our solution.

A Robot Cooked My Goose!

It’s lunch hour on a weekday and a small restaurant in central Beijing is packed to the gil s.Harried-looking waiters run from table to table to cope with the stream of orders,and the manager’s fingers fly like lightning over the calculator as she tallies up bills.In sharp contrast to the hectic activity,the little kitchen,visible through the long narrow glass window that partitions it from the dining hal,is a calm oasis.A lean but efficient army composed of three cooks is dishing out the orders,working in perfect coordination and harmony.
