Abstract
This study consisted of building two prototypes of an automated ambulance to assist injured astronauts to safety, and perform tasks deemed unsafe for humans. Prototype 1 tested methods of retrieving a test dummy and how drivers affect the overall success of the robot's ability to retrieve the dummy. Human driver tests consisted of measuring a designated learning time. Prototype 2, furthered the progress the EMSR by addressing the issues with Prototype 1.
1. Introduction
In 1989, President Bush permitted NASA to develop the International Space Station and attempt establishing a colony on Mars [1]. Increasing momentum and public interest in the push for Mars exploration gives relevance to the development of robots, such as developed in this study, to help assist future Mars astronauts.
2. Prototype 1
March 4, 2016 EMSR Terrain test: Prototype 1 traveled over rocks, grass and moderate bumps.
April 4, 2016 Human driver test 1 and 2 : learning and retrieval times of a human operators were recorded. The shortest retrieval times of both tests were female with the longest learning times.(As shown in Fig 1 and 2.)
MDRS testing: Operation “Meet the Neighbors: Carried payload through mud. (As shown in Fig 5.)
Human Driver Test at MDRS: Sole male operator’s learning and retrieval time broke the MCC tests’ pattern.
3. Prototype 2
Prototype 2 improved upon how the robot handles driving over difficult terrain. The motors on the arm were fully functional: the arm moved up and down and the claw opens and closed. On Eva the robot could pick up rocks soil samples, ranging in size, up to 12 centimeters in length.
