3 2018 First Responders 4-H Robotics Challenge The goal of the First Responders 4-H Robotics Challenge is to introduce participants to the concept of competitive robotics. This is done through a mission-based activity where youth design, build and program LEGO MINDSTORMS robots to solve easily defined tasks. The activity is performed on a small (4 x 4 ) game mat, using pre-defined mission pieces. Each mission has points assigned, based on achieving a set goal. Although the missions are predefined, the solutions for achieving those missions are very open-ended, and depend on the creativity and skill of the participants. This document defines the rules and operating procedures for the 2018 game. 1 Teams Teams will consist of 3 to 8 members. The age range of team members may be defined by the local event organizers. 2 The Game Team members will construct a robot, using ONLY LEGO parts. The robot will be controlled by a LEGO Mindstorms Brick. The robot will autonomously perform specific tasks. The team will have 2 minutes and 30 seconds to perform as many tasks as possible. 2.1 Competition kit The competition kit comprises the playing field mat and the mission models. The mat is available from the Garrett County 4-H Office. The mission models are constructed from a standard LEGO Mindstorm Education EV3 Expansion kit ( ). Competition kits can be shared among multiple teams. 2.2 Field Mat The field mat is a 48 x 48 vinyl banner which is mounted inside a wooden playing field for stability. The mat defines the various mission regions of the game and provides registration marks for positioning mission pieces Field Mat 2018 First Responders 4-H Robotics Challenge Page 3

4 2.3 Playing Field The field will be constructed of a ½ thick sheet of plywood (48 X 48 ) with 2 X 4 (studs) on edge to create a playing area of 45 X 45 (inside the 2x4 frame). The mat (48 X 48 ) will be installed between the 2 x 4 edge and the plywood. The playing field will be on a table or supported by two sawhorses 28 to 32 tall Field Mat mounted to Playing Field 3 The Robot 3.1 Allowed Materials Field Set-Up with Mission Models Robots must be constructed using the MINDSTORMS controllers (RCX, NXT or EV3) and any additional official LEGO parts. Non-LEGO parts will not be allowed. The robot must be programmed with LEGO Mindstorms software to perform the tasks autonomously. A maximum of the following motors and sensors may be used (does not include robot manipulators brought to the table during the competition): a. 2 x touch sensors 2018 First Responders 4-H Robotics Challenge Page 4

5 b. 2 x light sensors c. 1 x ultrasonic sensor d. 1 x lamp e. 1 x gyro sensor f. 3 x motors The following may not be used: a. Paint, tape, glue, and oil b. Non LEGO stickers c. Remote controls of any type 3.2 Robot Size The robot and any attachments must start completely inside of the Base area of the board and must not be taller than 12. After the robot leaves the Base area it may expand to any dimension Robot completely in the Base area note that the base area this year is the five sided base in the south of the mat with the planes or horse picture) 3.3 Robot Operation Handling the Robot The robot may only be handled by the team members while the robot is in the Base area. Once the robot completely leaves the Base area, the member cannot touch or in any way influence the movement of the robot until it comes back to Base (any part of the robot breaks the plane of the base) without a penalty Robot in Base While in Base, members my change programs or change parts on the robot. The robot will be considered in Base as soon as any part of the robot crosses into the Base First Responders 4-H Robotics Challenge Page 5

6 3.3.3 Mission Objects in Base Any objects that are to be brought back to Base must cross into the Base before a member touches the robot. Any mission that was in progress will be terminated if a member touches or in any way interferes with the robot or LEGO models outside of Base. Teams may re-run the mission, but game pieces will remain where they are when the robot was touched. The robot may leave Base and return as many times as time allows. The mission models that start in Base (south corner of mat this year) include the fire truck driver, the Smoke Detector battery, and the three traffic cones Touch Penalties If the robot is touched outside of the Base area it must be brought back to Base immediately and will be assessed a touch penalty. To assess the touch penalty, the referee will take one of the water pieces away for each touch penalty. If there is not enough water for the amount of touch penalties, the judge will begin taking away a piece of debris for each touch penalty assessed First Responders 4-H Robotics Challenge Page 6

7 4 Game Rules 4.1 Mission Models Mission models are constructed from a standard LEGO Mindstorm Education EV3 Expansion kit ( ). Instructions for construction of mission models will be provided on the State 4-H Robotics Challenge web site at It is the team s responsibility to construct mission models correctly. The field(s) at the competition may not be altered (consideration will be given if discussed with the referee). 4.2 Robot Rounds Each robot will play three rounds with the highest score of the three rounds counting toward the final award. Each robot round will last for 2 minutes 30 seconds. The round will be started at the referees call and the robot will be turned off by the referee at the end of the round. Teams will be given a minimum of 10 minutes between rounds. 4.3 Robot Operators Two members will be allowed at the table during the robot rounds. Additional team members must stand in the designated area and may tag in and out during the round. 4.4 Scoring of Mission Objects All scoring of robot missions are Based on the location of items at the end of the match. If an item is placed in scoring position and then moved by the robot, the item will receive the point for the final resting spot at the end of the match First Responders 4-H Robotics Challenge Page 7

8 5 Missions "Missions" are the definition of what the robot must do to gain points. Missions may be performed individually, or grouped together within a single program. They are defined as follows: 5.1 Smoke Detector The robot needs to put a new battery in the smoke detector. The robot must place the battery inside the hole in the smoke detector. As long as the round part of the battery is partially inside of the hole of the smoke detector, the mission is complete and 40 points will be awarded. The Smoke Detector is set-up on the outer edge of the second orange square to the left and covering about half of the third orange square to the left First Responders 4-H Robotics Challenge Page 8

9 Both of these would receive full points. 5.2 Water from the Fire Hydrant The robot needs to get water from the fire hydrant to the fire truck in baes. The water is released when the fire hydrant is opened. Each water is worth 5 points in Hydrant at the end of the game. If the water is released and taken back to base (hydrant must remain connected to the wall and close to its starting point) at the end of the game, 10 points will be awarded per water. If the water is placed inside the fire truck and the fire truck is at the Fire Detection area, 20 points will be awarded per water. There are a total of 4 waters First Responders 4-H Robotics Challenge Page 9

10 This shows the Fire Hydrant closed with the water placed inside it. The Fire Hydrant is set up so that the end of the hydrant is touching the wall Hydrant shown in the open position 2018 First Responders 4-H Robotics Challenge Page 10

11 The water is inside the fire truck in the Fire Detection area. 5.3 Debris Clean Up The robot needs to clear the road (wide black line) of debris after the accident. The debris can be returned to Base for 2 points per piece of debris or the debris can be placed in the bin in the Head zone for 5 points for each piece of debris. There are a total of 8 pieces of debris. Note the debris will be randomly located along the black line. The pieces along the black line will be placed along the line randomly and spread out First Responders 4-H Robotics Challenge Page 11

12 Pieces of debris in the bin in the Head zone. The bin is placed on the edges on the Head zone and against the wall. 5.4 Fire Truck The robot must recover the broken fire truck and bring it to the fire station (base). The fire truck in base is worth 15 points at the end of the match. The robot can also place the fire truck at fire detection area for 25 points. The set-up of the truck is with the back wheel of the truck inside the second yellow square (note the first square is not visible in this picture) against the black edge. The front wheel is on the black edge of the third yellow square First Responders 4-H Robotics Challenge Page 12

13 Top View of the Fire Truck Set-Up As long as the truck is crossing the edge of either area, it will receive full points. This applies to both the fire truck in Base and in the Crime Scene Detection area. Fire Truck in the Fire Detection area 2018 First Responders 4-H Robotics Challenge Page 13

14 5.5 Rescue The robot will need to pick up the injured people from the accident scene in the center of the table and transport them to locations for medical assistance. The robot must transport the two injured LEGO people (you will need to supply two LEGO people) to the Hospital and the Helicopter pad. One LEGO person must be transported to the Hospital (inside the Health zone) for 20 points and the other LEGO person must be transported to the Helicopter Pad (4-H Clover) for 20 points. A total of 40 points can be earned for this mission. Note that the people may be brought to base before being transported. Note: It does not matter which LEGO person you place in which area. As long as the LEGO person is crossing either the outer red edge of the 4-H Clover, or the black dashed line of the Health zone, the team will receive full points. 5.6 Traffic Cones The robot will need to assist with traffic control by placing traffic cones near the scene of the accident. The robot will deliver the traffic cones from Base to any of the 4 green circles to the left and right of the thick black line. 15 points will be awarded for a cone placed on the left side of the line and 15 points will be awarded for a cone on the right side of the line. Additional cones on the same side of the line will not count. The cones will be counted as long as the cones are touching the black line or inside of the green circles. The cones may be placed in either green circle on each side of the black line First Responders 4-H Robotics Challenge Page 14

15 This will receive full points since it is crossing the black outer rim of the green circle. Only one cone will receive points because the cones are on the same side of the black line. Both cones will receive full points as they are both on different sides of the black line and they are both in the green circles. 5.7 Fire Detection The robot will determine if the house is safe to enter by determining if the fire is extinguished. The robot must detect the color of the paper (either green or red) on the inside of the mission model and display on the robot screen the color for 45 points. The construction paper will be cut 1.5 X 2 and fastened to the rectangle connected to the vertical axle inside the model. Green on one side and red on the other. The construction paper will be the 8 color Crayola 96 sheet pack of 9 X12 sheets which is available at Walmart (# ). The color will be randomly set after the team has indicated they are ready to start the match. The team should not be able to visibly be able to see the color and set a program. The robot must use a sensor to detect the color First Responders 4-H Robotics Challenge Page 15

16 5.7.1 Fire Detection Set-Up 5.8 Robot Touch Penalties A touch penalty is assessed when one of the team members touches the robot when the robot is completely outside of the Base area, the robot is in contact with a mission model or in the act of scoring outside of the base area. Each time a touch penalty is assessed one of the water pieces will be taken away from the field. Water pieces in the original position will be taken first, and then water in Base, and finally water in the truck delivered to the Fire Detection Area will be taken away. If all the water pieces are removed as touch penalties, pieces of debris will be removed for additional touch penalties First Responders 4-H Robotics Challenge Page 16

17 6 Team Notebook Each team should document the building of their robot in a journal. Each day that the team meets: record plans for the day, pictures and diagrams of robot building process, and ending reflections. The notebook will be shared with the judges during the technical presentation. 7 Mission Point Scoring summary Mission Description Point Value 5.1 Smoke Detector 5.2 Water Released from the Hydrant The battery is placed inside hole in the smoke detector.
