Figure 7 shows the course layout for the Valve task. 

The Valve task consists of three sub-tasks:  (1) Close a first valve (1 point), (2) Close a second valve (1 point), and (3) Close a third valve (1 point).  Valves may be closed in any order.

The valves will control air flow in pipes, with indicators that visually show air flow.  For each of the three sub-tasks, completion requires turning the valve until the flow of air stops. 

One valve will be a 90 degree ball valve, with a 13 inch handle, that requires a rotation of 90 degrees to close.  The DRC Trials will use the “CS Ball Valve 3 Inch” (Grainger Part Number 1PRB9, or similar).  The valve will move upon application of no more than five pounds of force (5 lbf) to the tip of the handle.

Another valve will be a mid-size rotary valve that requires one (1) complete clockwise rotation to close.  The DRC Trials will use a “Gate Valve” body with a 9-inch diameter wheel handle (Grainger Part Number 1WPD6, or similar).  The valve will move upon application of no more than five pounds of force (5 lbf) to the edge of the handle.

Another valve will be a large rotary valve that requires one (1) complete clockwise rotation to close.  The DRC Trials will use a “Gate Valve” body with an 18-inch diameter wheel handle (Grainger Part Number 1WPD6, or similar).  The valve will move upon application of no more than five pounds of force (5 lbf) to the edge of the handle.

Initial positions for the rotary valves will be set by first closing them (so no air flows), and then opening them one (1) revolution.

The height of a valve center shall be approximately 40 inches above the ground, no less than 32 inches above the ground, and no more than 48 inches above the ground.  The center-to-center distances between the valves is approximately two (2) feet.

For an intervention during any of the sub-tasks, the robot will be returned to the start.

The appearance of the wall may not be as visually “clean” as the wall shown in the figure, and may have a different texture.
