This paper describes the development of Flutter, a new sensor-driven, robotics technology kit for in-school use with elementary-age students. Our development began by conducting focus groups with teachers (N=6) in which we guided a participatory design process. Through affinity diagramming, we identified science and math as areas of focus for the program; we also brainstormed project-topics with the...
Power wheelchair users suffering from cognitive or physical impairment often face difficulties in maneuvering their wheelchairs through crowded environments. Currently, users need to be continuously aware of all traffic around them to actively avoid all collisions. This is an especially difficult task since many wheelchair users are unable to accurately view or perceive their surroundings. Additionally,...
The proposed paper describes the Fire-HEXBOOT prototype's implementation, consisting of the hexapod-propulsion module, the fire detection and its extinguishing system. During the prototype testing some adjustments in terms of sensors, servomotor response times, balancing of the displacement structure have been solved and optimized. Specifically, the developed robot has mechatronic system dedicated...
This short paper presents a curriculum the author developed for introducing electrical and computer engineering (ECE) and computer science (CS) concepts to high school students. For enhancing the learning experience of the participants the program is built around a number of practical and fun activities which are meant to keep the students actively engaged. This material was offered for two cohorts...
Embedded systems for wearable robotics are ideally low-cost, lightweight, miniature, reliable and safe. They have high peak output and negligible standby power, are simple to use and program, can support high-performance real-time control loops and accept additional degrees of freedom, input and output devices. However, practical solutions cannot accommodate all of these criteria and compromises are...
This paper presents a design for a low-cost research robot based on the chassis of a Hexbug Spider, a remote controlled toy robot. Our modification replaces the robot head with a 3d printed adapter part which provides space for sensors, a larger battery, and a microcontroller board. In a second part of the paper we address the manufacturing process of such a robot. The presented robot costs far less...
MWSN is an emerging area of research and most of the work in the field of MWSN is done at the simulation level as there is hardly any cost effective hardware platform(node/mote) available for MWSN applications. To handle mobility, the MWSN node should be much more efficient than the nodes in static WSN. Moreover, a MWSN node should be capable of handling real time mobility control, path planning and...
Multi robot systems have been a popular area of research for over a decade because of their speed and efficiency in completing tasks. The control of such systems relies heavily on complex algorithms running on high end embedded system or personal computers acting as central nodes. As a result, implementing such systems is expensive. Despite having a range of real world applications, the high cost...
This article discusses the electronic readout design for tactile sensing transducers based on POSFETs (Piezoelectric Oxide Semiconductor Field Effect Transistors). The design approach, the proposed electronic architecture and the experimental results for validating the proof of concept are presented. This readout features a reduced number of circuits and is implemented with off-the-shelf electronic...
This paper presents a new solution for a field-reconfigurable modular micro mobile robot. The robot design encompasses some new attributes. It is small enough that it can be used for searching in tight spaces, where humans cannot easily reach and the robots can be adapted to many situations by attaching extra modules to enhance the robot¡¦s capabilities. The robot is auto-reconfiguring, that is when...
As technology becomes a greater part of our everyday lives it becomes more difficult to keep young children interested and engaged using conventional educational methods. While it can be observed that youngsters have only a few problems with operating their cell phones, it does not mean that this prepares them well for the challenges of the 21st century. Additional education is required that teaches...
Balancing small objects such as a normal pencil on its tip requires rapid feedback control with latencies on the order of milliseconds. Here we describe how a pair of spike-based silicon retina dynamic vision sensors (DVS) is used to provide fast visual feedback for controlling an actuated table to balance an ordinary pencil on its tip. Two DVSs view the pencil from right angles. Movements of the...
The advancement of technology in recent decades has brought computing beyond the desktop computer. With the focus on portable and interactive devices, it is necessary to equip the next generation of engineers with the necessary programming skills and a robust set of tools to create a wider range of applications. In the School of Computer Engineering at Nanyang Technological University (NTU), Singapore,...
This paper will explain a new way to communicate between mobile robots based on PC- Card and some sensors using in robot application or mobile robot research. The hardware interface with the Inter-Integrated Circuit System or shortly I2C bus system will be mainly described here. The mobile robot components, I2C bus system and some I2C slave devices are also introduced. Finally, the software is developed...
This paper addresses a platform-based design method of a real-time embedded system for controlling three-dimensional (3-D) swimming of link-based robotic fish. It involves mechanical design, hardware implementation, software design, and central pattern generators (CPG) inspired 3-D swimming control. With the ARM-based microprocessor AT91RM9200, the established hardware is well suited for complex computation...
Japanese offices are often cramped, cluttered, and allow a mapping robot very little room for maneuvering. Robot navigation research in Japan is hampered by these cramped spaces and a thorough search for robots that could map and maneuver in Japanese offices turned up unsatisfactory results: either the robots were too large, could not carry a relatively heavy payload, or did not have processing power...
