Lego nasa crawler1/18/2024 ![]() Graphic showing the parts of the engineering design process. Familiarize yourself with the engineering design process (shown in the graphic below) and use the following description to frame the challenge for students.NASA plans to continue sending missions to the Moon about once a year after that while also using SLS to launch robotic scientific missions to places like the Moon, Mars, Saturn, and Jupiter. SLS will be used in the Artemis program for a series of uncrewed and crewed missions, eventually carrying astronauts to the Moon during the Artemis III mission. A foundational piece of the program is the Space Launch System, a rocket that will allow for human exploration beyond Earth’s orbit. NASA’s Artemis program will return humans to the Moon by sending the first woman and the first person of color to the lunar surface. Upgrades to crawler-transporter 2 in 2016 allowed for an increase in the lifted-load capacity from 12 million to 18 million pounds to support the weight of the mobile launcher and future launch vehicles, including the Space Launch System (SLS) rocket and Orion Multi-Purpose Crew Vehicle. With the future of Space Exploration calling for super-sized exploration vehicles, NASA now needs super crawlers. The technology used to build these huge, reliable crawlers capable of such herculean tasks was deeply rooted in a region where giant machines excavated and extracted veins of coal. These mammoth vehicles first carried the Apollo Saturn V rockets, and later the space shuttles, before they were launched into space. How would you transport an 18-million-pound rocket and mobile launch pad three miles and deliver it upright for launch? What kind of grapple, end effector or robotic hand would be best suited for holding and moving such a massive object?įor more than 40 years, the twin crawler-transporters at NASA's Kennedy Space Center slowly traveled the gravel track between the massive Vehicle Assembly Building and the two launch pads at Launch Complex 39. 29, 1980, a crawler-transporter moves the space shuttle Columbia to the launch pad before the first shuttle flight, STS-1. Students without physical access to a robot can use a virtual coding environment, such as VEXcode VR or a virtual EV3 coding environment to develop block- or text-based code that can be executed on a virtual robot.Students should be encouraged to draw upon their personal and cultural experiences throughout the design process.The arm end effector design and delivery method are entirely up to the designer(s) as long as they are within the design constraints and meet the criteria for the challenge. The speed of the crawler may play a role in transporting the rocket safely to the launch pad, and the speed of the arm or end effector motion may affect the delivery of the rocket to the target in an upright position.The students will be applying their knowledge of ratios and rate reasoning to determine the appropriate number of rotations for the distance required in the challenge. The students need to have completed enough practice programs with their assigned robots to understand how to make their robots move straight for a distance using wheel rotations.This lesson can be completed individually or within a group, although groups of two to three students of varied skill levels are recommended. ![]() (Optional) VEXcode VR or other virtual programming environment (for use with no access to robot) Management Payload for the robot to transport (e.g., empty soda bottle or can) Defining and Delimiting Engineering Problems.Create an engineered model, limited by criteria and constraints, designed to achieve the task of solving a complex problem.Understand ratio concepts and use rate reasoning to solve real-world problems.Students will use the engineering design process to guide them in completing the challenge. Students design, build and program a robotic “super crawler” to transport a payload from a starting position to a target launch pad, use a robotic arm with an end effector to deliver the payload in an upright position and return the robot to the starting point.
