This paper presents the development of a low-cost vision-based robotic wheelchair system towards autonomous convoying. The non-holonomic follower vehicle obtains visual real-time pose data of a known coplanar target installed on the back of the leading vehicle. This allows the tracking vehicle to mimic the path of the preceding vehicle, while maintaining a(More)
This paper proposes a mechanism to derive quantitative descriptions of wheelchair usage as a tool to aid Occupational Therapist with their performance assesment of mobility platform users. This is accomplished by analysing data computed from a standalone sensor package fitted on an wheelchair platform. This work builds upon previous propositions where(More)
This paper documents the development of a passive technique for assessing a power mobility device user's driving proficiency during everyday driving activities outside formal assessment conditions by therapists. This is approached by first building a model by means of an Artificial Neural Network to infer longer-term destinations for discretized bouts of(More)
