This thesis will explain the process of developing an application for the humanoid robot Pepper. The app that was developed is a proof-of-concept type of application for researching the human-robot interaction especially with elder people with memory disfunctions. The technology stack chosen for the building this app consists of web-development tools, such as VueJS, Babel, and JavaScript. The thesis will describe how these are used in unison in this process. I will also describe some of the problems encountered while developing the app and provide possible solutions for the issues. Hopefully the solutions will help future developers.
