Collaborative robots (cobots) are presented as a way of business competitiveness by combining human skills with robotic advantages. The place of human operators in this context is the subject of much discussion. Including his role, his safety and his security. This study presents a methodological contribution for the management of cobotic projects. It aims to develop profitable, safe and acceptable solutions for the final users. This article presents the different steps of the design process of a collaborative robotic cell to improve a recycling laundry pods workstation. Initially, the current activity was analyzed through observations and interviews with users. Next, improvement scenarios were proposed, discussed and prioritized. After that, a feasibility study was carried out and led to technical prototyping. This was evaluated by end users to improve the solution before the investment.
