During the period of isolation of the hospitalized child, contacts between the child and his family are impaired. Being away from home as well as from the social and family circle can be harmful for the hospitalized child. It seems necessary to measure the impact of the use of such an assistance robot both on the user himself and his family. Thus, it seems relevant to scientifically validate the benefit of using such an assistance robot to break iatrogenic social isolation and to measure the impact of this use.

Inclusion Criteria:

• Children hospitalized in the pediatric hemato-oncology department whose duration of isolation is estimated to be greater than two weeks.
• Children who have accepted the robot and whose parents have accepted its use in their home.
• Agreement of holders of parental authority for the inclusion of the hospitalized child.

Exclusion Criteria:

• Patient or two parents who do not have a sufficient level of French for research.
• Cognitive or motor disorders in children, not allowing the use of the robot and/or the carrying out of semi-structured interviews.
• Cognitive disorders in parents and/or siblings that do not allow semi-structured interviews to be carried out.
