The following rules and regulations govern the weightlifting event of HuroCup, a robotic game and robotics benchmark problem for humanoid robots.
The latest official version of the rules of the game for HuroCup is always available from the HuroCup Facebook Page.
There are no significant changes to the laws of the game for weightlifting in the 2015 competition.
The goal of the weightlifting competition is to encourage research in actively balancing robots and robots that are able to walk under a heavy load and are able to compensate for varying centres of gravity.
The following laws describe the specifics of the weightlifting event. For general specifications relevant to all HuroCup events (e.g., robot dimensions, playing field and lighting, responsibility of the referees) please refer to General - HuroCup Laws of the Game.
[WL-1.1]: The weightlifting competition is played on a field with a minimum dimension of 1.8m by 1.8m. See Figure Weightlifting Field.
[WL-1.2]: The field is marked with three lines: (a) the start line, (b) the lift line, and (c) the finish line. The distance between the start line and the lift line is $LL, the distance between the lift line and the finish line is $LH.
[WL-1.3]: The width of all lines is $L.
[WL-2.1]: The lifting bar is a wooden, metal, or plastic bar with a width between 8 mm to 15mm. Two stops are used to mount the weights. The distance between the inner stops is at least 40cm. The total length of the lifting bar is between 50cm to 80cm.
[WL-2.2]: ] The ``weights'' used in the competition are standard 5 1/4 inch CDs or DVDs that must be lifted by the robot as seen in Figure Lifting Bar.
An example of a possible lifting bar and a schematic diagram showing the bar.
[WL-3.1]: A single robot competes in a match.
[WL-4.1]: Please refer to General - HuroCup Laws of the Game for detailed information about the players.
[WL-5.1]: Please refer to General - HuroCup Laws of the Game for detailed information about the referee and his or her duties.
[WL-6.1]: Please refer to General - HuroCup Laws of the Game for detailed information about the assistant referee and his or her duties.
[WL-7.1]: A single robot is designated the lifter. All other robots must be outside of the playing field.
[WL-7.2]: The only robot allowed to move during a run is the designated lifter.
[WL-7.3]: The lifter will be placed behind the start line.
[WL-7.4]: At the beginning of the try, the team will inform the referee how many CDs the team wants to attempt to lift and the referee will attach the desired weight to the lifting bar.
[WL-7.5]: The referee will signal the start of the competition by blowing the whistle.
[WL-7.6]: After the referee gives the start signal, the robot must pick up the lifting bar positioned at the start line.
[WL-7.7]: The robot must walk towards the lifting line while continuously carrying the weight below head height until a foot touches the lifting line.
[WL-7.8]: While at least one foot is touching the lifting line, the robot must lift the lifting bar above its head. The height difference between the low and high position must be at least $H.
[WL-7.9]: While keeping the lifting bar above its head, the robot must continue to walk towards the finish line. A lift is considered successful if the robot crosses the finish line with both feet and with the weight above its head.
Low and High Lifting Positions
[WL-7.10]: A robot is not allowed to leave the playing field.
[WL-7.11]: Each robot may have at most one human handler associated with it.
[WL-7.12]: The human handlers are not allowed to interfere in any way with other robots, the referee, or other human handlers.
[WL-7.13]: A human handler may only enter the playing field or touch his/her robot with the permission of the referee.
[WL-7.14]: The end of the competition is signaled by the referee by blowing the whistle a second time. The referee terminates the competition if
[WL-7.15]: A robot may continue in the competition as long as it has failed less than three tries. When the robot will be declared the lifter in the next round, then the team may choose a new weight for the next try.
[WL-7.16]: At the end of the try, another robot will be designated the lifter.
[WL-8.1]: The lifting bar is below the head of the robot while it traverses the zone between the lift line and the finish line.
[WL-8.2]: The robot handler touches the robot.
[WL-8.3]: Any infractions as listed by General - HuroCup Laws of the Game as far as they are applicable in this event.
[WL-8.4]: Any team that commits one of the infractions listed in this section will be penalized by having the try declared invalid.
[WL-9.1]: All robots that have not lifted successfully at least 0 CDs are automatically awarded no rank and 0 points.
[WL-9.2]: Among the robots that have lifted more than 0 CDs, the robots are ranked (i.e., 1st place, 2nd place) based on the maximum weight lifted successfully.
[WL-9.3]: For more details about the point allocation, please refer to Point Allocation [Organization - HuroCup Laws of the Game].
[WL-10.1]: In case two or more robots have the same number of points after all rounds in the weightlifting event, the sum of the maximum weight in all rounds will be used as tiebreaker.
[WL-10.2]: In case two or more robots have the same number of points after all rounds and are still tied after applying the previous tiebreaker, the maximum weight in a single round will be used as a tiebreaker.
