Several approaches have been proposed to assist humans in co-manipulation and teleoperation tasks given demonstrated trajectories. However, these approaches are not applicable when the demonstrations are suboptimal or when the generalization capabilities of the learned models cannot cope with the changes in the environment. Nevertheless, in real co-manipulation and teleoperation tasks, the original demonstrations will often be suboptimal and a learning system must be able to cope with new situations.

The animals were divided into two equal groups--an experimental one, with Mepitel (SCA Mölnlycke) dressings, and a control group with cotton gauze dressings. Microbiological and histological examinations and measurements of the wounds made on the 3rd, 7th, 14th, 21st and 28th days after the 3rd-degree heat burn was inflicted using the standard method.
