Route optimization using forecasting, wheelchair modelling and path planning

In routing systems, the capability to generate reliable safe routes depends on the integration of a path optimization algorithm with dynamics and models. In this work, a system based on a novel route optimization algorithm is considered. The sensitivity of the lowest energy solutions is analyzed considering different simplified wheelchair models. The aim is to implement a system for routing wheelchairs around obstacles so that more people can safely drive powered wheelchairs. Powered wheelchairs can positively impact participation, activity, wellbeing, pain and self-esteem. Systems described here can allowing more autonomous or collaborative driving, and enhance mobility of disabled individuals finding it difficult to use standard powered wheelchairs. The work included a small qualitative exploratory study that exposed three topics: (a) “situations that might benefit from path planning and obstacle avoidance; (b) “optimism concerning the use of technological systems on powered wheelchairs”; (c) “characteristics of disabled users that could benefit from using a powered wheelchair”. Findings indicated that the systems presented in this paper could help to overcome some of the difficulties in using powered wheelchairs.
