The client is a brain damaged young girl who has just grown into sleeping in a hospital style bed at home.
Her brain activity is such that constant movement is required for her to be in a calm state and the handling strategies used by the parents previously are no longer possible.
A wooden trestle was constructed to fit under the bed. Initially a rocking-chair construction was used, but eventually this was converted to a rocking-horse type suspension with the movement motorised. For the prototype a windscreen wiper motor was used to drive a cam driven push-rod. When it was realised that this was now an essential piece of kit that would be running all night every night an upgraded version was produced using an industrial motor/gearbox.
