REGULATIONS - JUNIOR SECONDARY GROUP

Operational Function of Device: Device can be controlled to move, surpass obstacles and pass through checkpoints on an iron vertical surface.

Materials: Production materials are not limited, but ready-made devices are not allowed.

Specifications:

1. Dimensions and weight restrictions:
   1. The construction should be composed of three parts: device, wire for control and controller.
   2. The device should be within the size of 21cm (length) x 21cm (width).
2. Restrictions on wire for control: The wire that connects the device and the controller should be at least 3m long.
3. Restrictions on source of power: The device should be driven by battery. The quantity used is limited to a maximum of 4 AA batteries at one time.

Sequence of Competition: The sequence of competition for each team will be determined by drawing.

Format of Competition: For the Junior Secondary Group, the teams are allowed to move their devices up and down the racecourse several times within the time limit.

Competition Ground: The competition ground includes an operation zone, starting/end point, racecourse (upward/downward course, obstacles and checkpoints), see[Figure 1].

Flow of Competition:

1. Before the competition, the operator and other team members should stand by at the [operation zone], see [Figure 2]
2. Each team should assign one operator to use the controller to operate all movements of the device, but he/she is not allowed to touch the device during the operation. The other team members are responsible for the repair work of the device, and they are not allowed to operate it. If the team only has one member, he/she will be in charge of both the operation and repair work of the device.
3. Before the competition, each team can use 1 minute to adjust their device.
4. After the preparation time is over, the team should stop all adjustments of the device, and follow the staff's instruction to locate the device at the[starting point].
5. The wire for control should be fixed to the [fixing point of wire for control]by the staff. During the competition, the operator and other team members must stay inside the[operation zone].
6. After the staff has signified the commencement of the competition, he/she will start to count the time. During the competition, all the team members must not do any actions that may facilitate the operation of the device (e.g. pulling the wire for control). Otherwise, it will be considered as violation of rules.
7. The time limit of the competition for each team is 5 minutes. When the time is up, all movements must stop. When the competition of each team is finished, the staff will record the number of checkpoints passed through and calculate the scores.

Method of Using the Racecourse:

1. At the start of the competition, the team can choose to start their competition in either an [upward] or [downward] course. The difference is:
   1. Upward course: The starting point is at the bottom, and the end point at the top.
   2. Downward course: The starting point is at the top, and the end point is at the bottom.
2. For the setting of the racecourse, see [Figure 1].
3. In total, there are 7 checkpoints on the racecourse. Each checkpoint is composed of 2 [sign poles]and 1 [passing line], see [Figure 3]. Scores will be counted only if the whole device has completely passed through the [passing line]of a particular checkpoint. The device should go [upward] or [downward] from the starting point, and scores will be earned by passing through the checkpoints. It is not necessary to follow the sequence of the checkpoints. The device can also skip some of the checkpoints. If the device passes through the same checkpoint more than once, the score for that checkpoint will only be counted once. When the device arrives at and completely passes through the end point of a particular course, the competition of that particular round is considered to be finished. The time limit of the whole competition for each team is 5 minutes. During this time, the device can repeatedly go [up] and [down] the racecourse to pass through the required checkpoints in order to earn scores and complete the competition.

Calculation of Scores: The total scores will be counted by the number of scores earned with the 5-minute competition. The team with the highest score will win. The scoring and calculation method is as follows:

1. [Checkpoint Score]: Calculate the scores earned by passing through checkpoints

   Number of Checkpoints Passed through	Scoring Method	Checkpoint Scores	Example
   1	20	20	Within the 5-minute competition, the device has moved [up] to pass through 3 checkpoints, then moves [down] to pass through 2 checkpoints, and moves [up] again to pass through 3 checkpoints. The total Checkpoint Score is: 3x20 + 2x20 + 3x20 =160.
   2	20+20	40
   3	20+20+20	60
   N	20+...+20	20*N

2. [Bonus Score]: If the device can pass through all the checkpoints in either an [upward]or[downward]course of a particular round, the team will earn a Bonus Score of 70 scores upon completion of that round of competition. Then the team can continue with the competition by moving the device in upward/downward courses of the subsequent rounds to earn more bonus scores by the same method.
3. [Score Deduction]caused by violation of rules: If the device touches the[sign pole]in any way during the competition, 5 scores will be deducted as penalty. However if the same [sign pole] is touched more than once in the same round, the score will be deducted only once.
4. [Total Score]: The calculating formula is [Checkpoint Score] + [Bonus Score] - [Score Deduction] = [Total Score]. The team with the highest [Total Score]will win. If more than one team has the same highest [Total Score], the team that has passes through more checkpoints will win. If the number of checkpoints that they have passed through is also the same, then the team that has a heavier device will win.

Obstacles: Several obstacles will be put in the Competition Ground, as in [Figure 4] (format) and [Figure 1] (location). The teams can use different ways that abide by the rules and regulations of this competition to get cover the obstacles. Alternatively they may choose to bypass them and continue with the competition.

Completion of Competition: The competition can be completed in one of the following ways

1. Completion within the time limit: The total Checkpoint Scores obtained by the device that moves or stay in the Competition Ground within the 5-minute time limit will be recorded.
2. Termination of competition before the time limit: If all team members agree, the competition can be terminated before the 5-minute time limit is over. The Checkpoint Scores obtained before the termination will be recorded. However the competition time will still be recorded as 5 minutes.

Maintenance:

The contestants can perform maintenance work on the device, wire for control and controller (including changing of parts and batteries) during the competition. While the repair work is in progress, the competition time continue to be counted. The scores obtained prior to the maintenance in that particular round will not be counted. If any repair work is required during the competition, the contestants should notify the staff concerned before they can enter the competition ground to get their device and perform the maintenance. After the maintenance work is finished, the contestants have to reset their device at the [starting point] of that round in the competition ground to restart the competition from that particular round.

Reset:

If the device fails to continue operating due to any accidental situation, the contestants may reset the device after notifying the concerned staff. The device must be reset to the[starting point] of the round of competition. The time of competition will continue to be counted, and the scores obtained prior to the reset action of that particular round will not be counted. The following are some examples of situations in which the device may be reset:

1. The device is deviated from the racecourse;
2. The wire for control winds around or hinders the racecourse, affecting the running of the competition;
3. Any maintenance of the device, wire for control and controller;
4. The device becomes out of control;
5. As requested by the contestants.

Violation of Rules: The penalty for violation of rules in the following situations will depend on their seriousness. The team can be disqualified for the competition from serious situation.

1. The device causes damage to the racecourse in any way during the competition;
2. The contestants touches the device during the competition without notifying the staff;
3. During the competition, any team member that is not the specified controller touches the device;
4. The dimensions of the device do not follow the specifications listed in the rules and regulations;
5. The contestants uses devices that have not been inspected by the Organizer of the competition;
6. Without permission from the staff, the contestants enter the restricted area of competition ground during the competition;
7. The contestants not following the instruction of the staff during the competition;
8. After the commencement of the competition, team member(s) do(es) any actions that may facilitate the operation of the device (e.g. pulling the wire for control).

Others:

1. All participants should pay attention to electrical safety.
2. Please bring your own tools. No tools will be provided by the Organizer.
3. All participants are welcome to use the testing ground in the Museum during opening hours before the competition.
