1.    General aspects:
The competition is open to all robotics enthusiasts.
Teams of one or more members are allowed.
The robots will have to meet the requirements presented in the Robot Characteristics section.
The competition consists in 3 challenges.
 
2.    Robot characteristics:
A. The robot must be a two legged walking humanoid biped that must shift its center of gravity to maintain its balance when walking.
B. When walking, one foot must lift off the floor, while the other foot is balancing the robot.
C. When walking, the foot that balances the robot must have a knee-joint angle greater than 90 degrees. At any point if this is not the case, the robot will not be considered walking.
D. The feet can be of any shape and form as long as all of the following are maintained:
a. The robot’s foot is defined as the part of the robot that is contacting the surface of the arena (ground).
b. The maximum length (size) of the foot must be less than 50% of the length of the extended robot’s leg. The leg length is defined as the distance between where the robots foot touches the ground and the axis that connects the leg to the upper body of the robot.
c. The maximum length of the foot must be less than 20 cm.
E. When robot is standing or walking, a rectangular outline around the left and right feet shall not overlap.
F. The robot must have 2 arms. Each arm extended length shall not exceed the extended leg length.
G. The robot must have a head.
H. The robot’s height must be greater than 30 cm but less than 80 cm.
I. The robot must be equipped with a start switch or sensor.
J. The robots must have displayed a number, offer by the organizers, on the outer casing of the robot in a visible place. The number it is used to identify the robot by the referee and can be found in the Team's Folder (details in appendix 1)
 
3. Game area:
A. The structure of the staircase (for Challenge 1) is presented in APPENDIX A.
B. The structure of the Obstacle Sprint (for Challenge 2) is presented in APPENDIX B.
 
4. Course of the competition:
The competition consists in 2 challenges. The robot which claims the biggest number of points wins.
 
4.1 Challenge 1: Stair-climbing
 
4.1.1. Aim of the challenge:
The robots compete one after each other. Each robot must reach the top of the staircase as fast as possible climbing one stair at a time, using his legs. Touching the staircase with other parts is not permitted.
 
4.1.2. Course time:
Time is measured from the start signal until the robot reaches the top of the staircase. The robot is deemed to have finished the challenge when it’s both feet are in contact with the top of the staircase. The maximum time admitted to complete this challenge is 5 minutes, at this time the robot position shall be noticed for scoring.
 
4.1.3. Timekeeping:
Time must be measured with an electronic gate system or by a judge with a stopwatch , based on the availability of  equipment. In either case the recorded time shall be final.
 
4.1.4. Autonomous control:
Once the start signal has been given the robot must remain fully autonomous or it will be disqualified. The robot must be disconnected from any network during the challenge to prevent outside intervention.
 
4.1.5. Interruptions:
A. If a robot falls of the staircase it gets a second chance to complete the challenge. The robot will be place at the first step.
B. If a robot falls of the staircase or gets stuck because of various reasons (low battery, hot motor, script error, etc.) it gets a second chance to complete the challenge. A time interval up to 10 minute shall be granted to solve the problem before the retry. The robot will be place at the first step when the restart will occur. In case of restart, the best attempt shall be considered for scoring.
C. If a team refuses the second chance or the robot cannot the fixed in the given interval, the first attempt shall be considered for scoring.
 
4.2    Challenge 2: Obstacle Sprint
 
4.2.1. Aim of the challenge:
The robots will compete one after the other. The aim of the game is that a robot who walks in two legs must complete a course with obstacles in the shortest time.
 
4.2.2. Challenge course:
A. The time in with the robots are allowed to finish the course is 90 minutes. Depending on the number of competitors the time can be extended or reduced.
B. Each root has in total 3 attempts. The robots have 3 time slots, each slot has a 30 minutes time limit.  In each slot a robot have the right to make only one attempt to finish the course.
If one robot will not come to make his attempt in one slot, he loses the right to do it. There are not allowed two attempts in one slot. The time slots can be extended or reduced depending on the number of competitors.
C. One attempt has a time limit of 3 minutes to be completed. If the robot get stuck is allowed one restart. The robot will have the restart from the start position.
D. If the robot doesn’t finish the course in 3 minutes it will be stopped and the distance covered will be recorded.
E. The final classification will be made taking in consideration the best time for each robot.
F. No objections shall be declared against the judges' decisions. If there are any objections the team, can be disqualified from that match.
G. Until the homologation, all the teams will stay in the room reserved for them (the room will be marked in the area map from the team’s folder). Each challenge will have a room. The teams can leave the room only when they are called to the competition area. Each team will be called by a competition official, when they need to go to the waiting area, which is near the competition area (details in appendix 1).
H. After a trial is over, the teams must return in the room reserved for them.
I. Each team has the responsibility to follow the starting grid (schedule), displayed on the website and in the teams room. PLEASE DON’T BE LATE, WE WILL NOT WAIT!!!
 
4.2.3. Time and distance keeping:
Time is measured from the start signal until the robot reaches the finish line. If a robot didn't finish the challenge in time or got stuck, the distance covered shall be measured. The best time or distance shall be kept for scoring.
 
4.2.4. Autonomous control:
Once the start signal has been given the robot must remain fully autonomous or it will be disqualified. The robot must be disconnected from any network during the challenge to prevent outside intervention.
 
4.2.5. Interruptions:
A. If a robot gets stuck because of any reasons it has the right to one restart.The robot will have the restart from the start position.
 
5.     Scoring:
 
5.1. Challenge 1: Stair-climbing
The robot who will reached the top of the staircase in the allowed time, will receive 10 points. The rest of the robots will be ranked depending on which step they arrive on the staircase. If more robots stop on the same step they will we ordered using the time.
The minimum amount of points obtained in this challenge shall be no lower than 1 point.
 
5.2. Challenge 2: Obstacle Sprint
The robot that will finish the course and will have the best time, will receive 10 points. The rest of the robots will be ranked using the time and the position on the course. If more robots stop on the same place they will we ordered using the time.
The minimum amount of points obtained in this challenge shall be no lower than 1 point.
 
5.3 Winner
The final ranking is made by summing the points from all challenges for each robot. The robot with the biggest number of points wins the competition.
 
6.    Objections:
A. There won't be any objections on the jury's decisions.
B.  If there is any problem with the regulations ,any complains or any deviations from the rules observed , the objection must be addressed by the team captain to the organizers , or in their absence to the members of the jury.
 
7.    Flexibility of Rules:
A. As long as the concept and fundamentals of the rules are observed, these rules shall be flexible enough to encompass the changes in the number of players and of the contents of matches.
B. Modifications or abolition of the rules can be made by the local event organizers as long as they are published prior to the event, and are consistently maintained throughout the event.
 
8.    Responsibilities:
A. Participating teams are always responsible for the safety of their own robots and are responsible for any accident caused by the members of the team or robots.
B. The University POLITEHNICA of Bucharest and the Faculty of Electronics, Telecommunications and Information Technology will never be responsible for any incidents/accidents caused by the participating teams and their robots.
