Approximately 15 nurses per hospital were interviewed, selected from areas with the most patient contact, as well as the responsible biomedical engineers.
Therefore, only the head nurses of each hospital ward, two nurses per ward, and the biomedical engineers within each healthcare institution were included.
In the healthcare sector, there is a tendency towards corrective rather than preventive measures, with emphasis on corrective maintenance due to workload, staff shortages, lack of materials and supplies, and budget constraints.
Fig. 5 shows a usage test from the perspective of a biomedical engineer, who would be responsible for managing and using the bot's settings [29].

The engineering strain components are given by e1 = u1,1,e2= u2,2,e4= u3,2,e5= u3,1,e6= u2,1 + u1,2, (12) and the electric field components by E1 = −φ,1 E2 = −φ,2. (13) The compatibility equations are given by e2,11 + e1,22 − e6,12 =0,e4,1 − e5,2 =0, (14) E2,1 − E1,2 =0.
Material Constants and Loading.
To see different material symmetry we rotate the material axes relative to the spacial axes.
