Suggested requirements for an fMRI compatible robotic device.

Contain no ferrous materials and be fully MRI/fMRI compatible

Be mechanically safe to avoid distress or possible harm to the infant

Be able to provide stimulation synchronized with fMRI acquisition

Be able to induce stimulation patterns at a controlled amplitude and frequency capable of eliciting robust functional responses

Be possible to monitor the operation of the stimulus remotely to ensure consistent stimulation was occurring and that no potentially harmful events could occur

Be light, small, and flexible enough to avoid the infant suffering movement restriction or discomfort

Not additionally induce head movements and so avoid resulting image artifacts

Be easily cleanable to prevent infection spreading from one infant to another

Be capable of presenting a stimulation type and pattern, which is appropriate for the neurodevelopmental stage of the study population
