System for effecting actions over vertical surfaces

A whiteboard printer suitable for creating an image on a substantially vertical surface, the whiteboard printer comprising:

• end effector means for performing an action over the substantially vertical surface;
• effector platform means for receiving and carrying the end effector means;
• means for moving said effector platform means consisting of:
• first effector platform positioning means connected to the effector platform by a first wire, the first effector platform positioning means for moving the effector platform in a first variable direction;
• and
• second effector platform positioning means connected to the effector platform by a second wire, the second effector platform positioning means for moving the effector platform in a second variable direction;
• and
• coordinating means connected to and in communication with the first and second effector platform positioning means, the coordinating means for controlling the first and second effector platform positioning means to move the effector platform in a desired direction.

A whiteboard printer suitable for creating an image on a substantially vertical display surface, the whiteboard printer comprising:

• an end effector;
• an effector platform receiving and carrying the end effector;
• an effector platform positioner consisting of:
• a first effector platform positioner that moves the effector platform in a first variable direction, the first effector platform positioner being connected to the effector platform by a first wire;
• and
• a second effector platform positioner that moves the effector platform in a second variable direction, the second effector platform positioner being connected to the effector platform by a second wire;
• and
• a computer-controlled coordinator that controls the first and second effector platform positioning to move the effector platform in a desired direction.
