2016 ATMAE Robotics Obstacle Course Information, Objectives and Rules
- The course will be navigated one team at a time.
- Each team will be required to navigate through a robotic obstacle course that includes sections where your robot will have to climb, follow a marked trail, collect objects, unload those objects, and sort the collected objects.
- For the course layout, see the diagram below. The obstacles are described below.
- Portions of the Robotics Obstacle Course will be autonomous.
- The first portion of the obstacle course the robot will be controlled manually. The operator will need to pilot the robot through the first set of obstacles, burlap climb and teeter-totter (see description of each below). The robot will need to climb both up and down the burlap climb obstacle, then carefully navigate the teeter-totter obstacle. Once these obstacle have been cleared the driver will the drive the robot to the spot where they would like to start the autonomous second stage of the course.
- For the second portion of the course, the robot will need to traverse a marked path, autonomously and along the way stop, pick up and store 5 blocks that will be placed on the marked path. The blocks will be 3D printed 2” cubes (see description of blocks below).
- After the fifth block has autonomously been loaded onto the robot, the operator can resume manual control of the robot. The robot must then be guide back to the climbing obstacles where it must climb up and down both the teeter-totter and burlap climb obstacles and proceed back the starting area.
- Once the robot returns to the starting area the robot will need to autonomously unload the 5 blocks it is carrying. The blocks must be unloaded 1 block at a time.
- After all 5 blocks have been unloaded the operator will once again take control manually and arrange the 5 blocks to spell out ATMAE. The blocks must be placed in the correct order, but the blocks do not need to be in the proper orientation. The blocks can have a maximum spacing of 1.5” between them to be considered in an acceptable position.
- The team with the fastest time, including any penalties incurred, will win the obstacle course event.
- While attempting the burlap climb and teeter-totter obstacles, teams will be allowed to have up to 2 team members beside the obstacles to catch their robot should it fall off one of the obstacles to protect the robot from damaging itself. The team members should under no circumstance put their hands on the robot other than to protect the robot from being damaged. If a judge feels that a team member handling a robot has given any unfair advantage to their team, the team will be disqualified from the obstacle course event.
- If a robot falls while climbing either the burlap climb or the teeter-totter obstacles, a 20 second penalty will be accessed and the robot will be placed at the beginning of that obstacle for another try. Each team will be required to make at least three attempts at each climbing obstacle. If you would like to restart the obstacle, tell the judge so, but do not move the robot until the judge tells you it is ok for you to move it. If after three failed attempts, and 3 penalties of 20 seconds, the team wishes to continue to the next stage of the competition they can do so, but they will incur an additional 1 minute penalty (total penalty time would be 2 minutes).
- Each robot must attempt the climbing obstacles both on its way to the tape following area and returning to the assembly area.
- When the robot is placed in autonomous mode to follow the tape, if the robot strays from the marked path (becomes lost), the operator can switch back to manual control and drive the robot back to the beginning of the marked path where autonomous mode must be restarted. All of the turns the robot is required to make will be less than 90 degrees.
- During the autonomous portion of the course, if the robot has not picked up any blocks, there will be no penalty other than time lost in the restart. If the robot has picked up a block or blocks, the block(s) can remain on the robot, but a penalty of 20 seconds per block will be added to the final time.
- A robot can only be restarted 2 times (a total of three attempts). After the third unsuccessful attempt at following the marked path, if the team wishes to continue, they will be allowed to manually pick up the blocks if they choose to do so, but a 5 minute penalty will be added to their final time. For each of the blocks that have been picked up while in autonomous mode, and remain on the robot, 1 minute will be deducted from this penalty. For each of the blocks that have been picked up manually, and remain on the robot, 20 seconds will be deducted from this penalty.
- When the robot has returned to the start/assembly area, it must be switched back into autonomous mode for the unloading of the blocks. The blocks cannot be dumped, they will need to unloaded one at a time. A conveyor system will be allowed as long as the blocks are coming off of the robot one at a time.
- Once all of the blocks have been autonomously unloaded, the driver can switch back into manual mode where they must arrange the blocks in a manner that spells out ATMAE. The blocks can have a maximum spacing of 1.5” between them to be considered to be in an acceptable position. The blocks must be placed in the correct order, but the blocks do not need to be in the proper orientation.
- Each team will be timed individually in the case of penalty time that may need to be accessed.
- The robot must stay within the marked off competition area for the event. For each instance a robot leaves the area, a five (5) second penalty will be added to the final time. A robot will be considered out of the area if one wheel or track is completely and clearly over the boundary. The only exceptions to this rule will be on the climbing obstacles when three attempts have been made and the robot is going around the obstacle.
- The first obstacle is a climbing obstacle called the Burlap Climb. It is a simple concept, burlap material is stretched from end to end going over the top of a PVC frame. The robot will have to climb up and over this obstacle before it can proceed to the next obstacle.
- The PVC frame will be constructed of standard ¾” schedule 40 PVC piping. The fittings that will be used are all standard fittings that are readily available. The PVC pipe and fittings are available at any Lowe’s, Home Depot, or most hardware stores.
- The burlap material seen in the photo was purchased at Wal-Mart, but it is a generic burlap material and can be purchased almost anywhere material is sold. The material purchased to be used on the obstacle was 4’ wide, so we folded the burlap material in half making it 2’ wide and making the burlap two layers thick. We purchased three yards of material to give us the length we needed to stretch from end to end of the PVC frame. The burlap will be sewn at each end so a piece of the PVC pipe can be put through on each end. After the ends have been sewn, if you were to lay the burlap flat, it should measure 90” from end to end.
- To keep the ends of the frame from being pulled up by the burlap, a ¾” diameter steel rod will be inserted into both long sides of the PVC frame. The rods lengths are between 70” and 72”.
- A list of PVC cut lengths and the number of fittings is provided below.
- The second obstacle is a climbing / balance / control obstacle called the Teeter-Totter. Again the concept is simple, a 8’ 1” long 15 ¾” wide shelf is placed over a PVC frame and the robot will need to drive up and over.
- The PVC frame is constructed of standard ¾” schedule 40 PVC. The fittings are all standard fittings. The PVC and fittings is available at any Lowe’s, Home Depot, or most hardware stores. A list of cut lengths and number of fittings is provided below.
- The shelf seen in the photo was purchased at Lowe’s, but is a generic piece of shelving and can be purchased anywhere shelving is sold.
- The shelf is held in place by three 1” galvanized steel 2-hole pipe straps. The straps were attached at the center of the shelf.
- To hold the shelf in place, three 1” galvanized steel 2-hole pipe straps were used at the center of the shelf.
The blocks that are to be picked up by the robot while following the marked path will be 2” x 2” x 2” and printed on a 3D printer using HIPS filament. The blocks will be marked with letters that when arranged correctly, will spell out ATMAE. The blocks will either be printed blue and the letters will be white or the blocks will be white and the letter will be blue. If your team has printed a set of blocks for practicing and you would like to use your own blocks during the competition, you will be allowed to do so if your blocks are approved by a competition judge prior to the competition.
