A novel method for controlling a robotic mobility platform, the WeeBot, is presented. The WeeBot permits an infant seated on the robot to control its motion by leaning in the direction of desired movement. The WeeBot hardware and software are discussed and the results of a pilot feasibility study are presented. This study shows that after five training(More)
In this paper we present the results of a study to determine the effect and efficacy of a Virtual Reality game designed to elicit movements of the upper extremity. The study is part of an on-going research effort to explore the use of Virtual Reality as a means of improving the effectiveness of therapy for children with motor impairments. The current study(More)
OBJECTIVES To assess the feasibility of a robotic mobility device for infants using alternative control interfaces aimed at promoting early self-initiated mobility, and to assess the effects of a training protocol and robot experience. DESIGN Observational and pre-post quantitative case studies. SETTING Standardised, research laboratory and day-care(More)
This paper presents a single-subject feasibility study of a motion-based VR game designed to provide benefits similar to constraint-induced movement therapy for children with cerebral palsy, while providing a more enjoyable experience. The game was designed to encourage the child to perform the desired therapeutic movements by allowing him to interact with(More)
Tots on Bots is a research project developing robotic-based mobility platforms for children with motor impairments. Independent mobility is crucial in the development of typical infants, and is missed by children with physical disabilities. We are looking to provide mobility to children as young as six months old using robot-powered devices. Children use(More)
The onset of crawling in infants contributes to cognitive, perceptual, social, and emotional development. Conversely, infants with motor impairment that delays or prevents autonomous mobility often have associated developmental delays. Evidence suggests that providing mobility may have positive developmental outcomes, however powered wheelchairs may not be(More)
Children with cerebral palsy (CP) often present asymmetrical or unilateral impairments that limit the use of their upper extremity, a condition known as learned nonuse or developmental disregard. Children may be unable to perform daily functional tasks that require the coordinated use of both arms. Some form of constraint-induced movement therapy (CIMT) is(More)
BACKGROUND The ability of the earth to sustain health among humans and in the natural world is under threat from overpopulation, environmental degradation, and climate change. These global threats are anticipated to harm health and human occupation in many direct and indirect ways. Strategies are needed to mitigate the effects of these threats and to build(More)
In this pilot study we investigated the ability of five infants from 6 to 9 months of age to learn to drive the WeeBot, a mobile robot controlled by weight shift over a Wii balance board, over five training sessions. Infants demonstrated continued improvement in driving performance in a training protocol and in time-in-motion and goal-directed behavior(More)
