For those who don’t follow SeaPerch (you should) would have missed that the obstacles for the 2015 SeaPerch events have been announced.
There are two categories:
An underwater remotely operated vehicle (ROV) must be able to maneuver successfully under its own power. If a vehicle cannot maneuver to the appropriate location to perform its task, the vehicle is of no use.
The submerged obstacle course involves large rings (22″ minimum diameter), oriented in any direction, through which the vehicles must travel. Teams must navigate through the obstacle course, surface, then re-submerge and return through the course to the end. Consideration of optimal maneuverability, control and speed should be given when constructing your SeaPerch (thruster placement and orientation, tether attachment, buoyancy and ballast, etc) and control box. Scores for this round will be based on the fastest time for successfully navigating the obstacle course.
There are five (5) -22″ diameter hoops in the obstacle course.
While many roles for ROVs require power, most require the ability to perform delicate tasks remotely. These tasks will require students to perform multiple independent tasks that will test their ability to operate their SeaPerches with finesse.
The course consists of three stations in which the vehicles will have to maneuver and actuate equipment on the pool floor. The max pool depth for this event is 5′
The first task will be a series of 5 targets that will have to be manipulated by poking the activation pad. The activation pad will need to be depressed up to 3” in order to the toggle the target. The targets will range in size and therefore difficulty. The inner diameter of the targets is as follows: 1”,1-1/2”, 2”, 2-3/8”, 3”.
The heights of the target centers will vary from 2” to 6”. Each target center is separated by 4”
The second task will be a series of 5 rods that will have to be lifted and placed into a series of vertical holders of different sizes.
Each rod consists of a 6” length of ½” PVC pipe with a polypropylene rope loop on one end and a small weight in the other. This design allows the rod to stand up when left freestanding in the water. The holder from which operators will have to retrieve the rings is constructed of 1” PVC pipe and will leave at least the top 2” of the rod and the entire loop exposed.
Operators will have to position the rods in one of three Vertical pipe sections with the following inner diameters: 1”, 1 ½”, 2-3/8”. More points are given for placing the rod in the smaller pipe.
The third task will require teams to actuate a device to the side. A ladder or abacus type device will stand vertical in the water. The device is made of 1” PVC pipe with the rungs at different distances apart, starting at 3-1/2” to 7” apart. On 5 of those rungs will be a PVC collar made of 1-1/4” PVC pipe. This collar will be 2″ in length. Not all rungs will have collars on them to be actuated and will serve as guard rungs for the collars. These collars will have to be slid from one side of the rung to the other in order to be placed in the brightly painted area on the rung. The direction that the collar needs to be actuated will alternate from collar to collar.
