  Socially Assistive Robots (SARs) offer great promise for improving outcomes
in paediatric rehabilitation. However, the design of software and interactive
capabilities for SARs must be carefully considered in the context of their
intended clinical use. While previous work has explored specific roles and
functionalities to support paediatric rehabilitation, few have considered the
design of such capabilities in the context of ongoing clinical deployment. In
this paper we present a two-phase In-situ design process for SARs in health
care, emphasising stakeholder engagement and on-site development. We explore
this in the context of developing the humanoid social robot NAO as a socially
assistive rehabilitation aid for children with cerebral palsy. We present and
evaluate our design process, outcomes achieved, and preliminary results from
ongoing clinical testing with 9 patients and 5 therapists over 14 sessions. We
argue that our in-situ Design methodology has been central to the rapid and
successful deployment of our system.
