| − | == Game Description ==
| + | |
| − | | + | |
| − | The game consists of a three-round based interaction between the human player and a robot within an arena — possibly with some predefined obstacles, where the robot tries to reach a specific target and the human player attempts to prevent that by pressing a touch sensor attached to the robot.
| + | |
| − | | + | |
| − | There exits 3 specific regions defined by how far the robot detects the player in relation to itself, namely: A, B and C, where
| + | |
| − | *Region A: denotes the critical region such that the human player can perform an attempt to push the robots sensor.
| + | |
| − | *Region B: Defines the medium distance meaning that the player is search for an opportunity to perform an strike.
| + | |
| − | *Region C: Is the furthermost one and the human prevalence in it has some side effects.
| + | |
| − | | + | |
| − | | + | |
| − | == Game Rules ==
| + | |
| − | | + | |
| − | *Rule 0: at the beginning of a round the players are apart from each other and the robot detects the human player’s position within region C.
| + | |
| − | | + | |
| − | *Rule 1: at each round the human player must try to prevent the robot from reaching its target by pressing its touch sensor.
| + | |
| − | **Consequence: if (at any time) the human player succeeds on pushing the robot touch sensor then he wins the current round and Rule 3 is applied. On the other hand, if the robot accomplishes Rule 2 he loses the game and Rule 3 is also applied.
| + | |
| − | | + | |
| − | *Rule 2: at each round the robot must try to reach a specific spot in the arena.
| + | |
| − | **Consequence: If the robot reach its target spot it wins the round and Rule 3 is applied. On the other hand, if he has its sensor pressed (at any time) he loses the round followed by the application of Rule 3.
| + | |
| − | | + | |
| − | *Rule 3: at the end of each round except the last one, the players restart a new round being apart from each other and the robot must be detecting the player’s position within region C (Rule 0).
| + | |
| − | **Consequence: the beginning of a new round.
| + | |
| − | | + | |
| − | *Rule 4: at any time, if the human is detected inside region A and stays there for more than 2 seconds then the robot earns the right for a 5-secs free run.
| + | |
| − | **Consequences: disables the touch sensor (which returns to function after the free run); The human loses the round if he makes any contact with the robot or blocks its trajectory for more than 2 seconds.
| + | |
| − | | + | |
| − | *Rule 5: After entering the region A the player has to wait for 5 seconds without touching the robot and only after that period of time he can perform a new attempt to push the robot’s touch sensor.
| + | |
| − | **Consequence: The human loses the round if he makes any contact with the robot or blocks its trajectory for more than 2 seconds.
| + | |
| − | | + | |
| − | *Rule 6: at any time, if the human player stays in region C for more than 10 secs then the robot earns a 7 seconds free run.
| + | |
| − | **Consequence: same as Rule 4.
| + | |
| − | | + | |
| − | *Rule 7: The human player cannot be closer than a certain range T from the robot’s target.
| + | |
| − | **Consequence: If this rule is broken the robot earns a 3 seconds free run with its touch sensor disabled (the sensor returns to function after the free run).

| − | == Winning Conditions ==
| + | |

| − | *Allow more than one human player; | + | |
