This wheelchair using artist with restricted movement of hands wished to be more independent.
A 12V battery was used to drive the ex-windscreen wiper and window winder motors for up/down movement and rotation. The counterbalanced easel can be raised, lowered and/or rotated by two large rocker switches located alongside the artist. Very little manual effort is required to move the rolling frame laterally. The artist has just enough grasp to manipulate his brushes gripped in a special holder.
The client can now reposition the canvas himself, work on much larger portraits and has greatly speeded up his output.
