Summary Draft 2 of NASA's Perseverance rover navigation systems.

-


Team : Ruth and Heng Kiat:

In the article, "Mars 2020 Mission Perseverance Rover" (n.d), the National Aeronautics and Space Administration (NASA) documented respective systems of the Perseverance Rover such as the navigation system that encompasses multiple instruments, namely, the Inertial Measurement Unit (IMU), Navcam, and Hazcam.

The article states that the IMU is a system composed primarily of gyroscopes and accelerometers, which give the rover directional information on its location using three-axis data. As the rover advances, the data collected on its position is utilized to make accurate vertical, horizontal, and side-to-side motions as well as to ensure safe navigation on the terrain. 

NASA also mentions that their Navcams and Hazcams are cameras that produce stereo images displaying the immediate surroundings for detection and tracking of potential hazards in addition to supporting a safe path to navigate. In conclusion, these features constitute a fraction of NASA's navigational system which aims to ensure safe navigation of the rover on Mars.

 "Developing excellent communication skills is absolutely essential to effective leadership. The leader must be able to share knowledge and ideas to transmit a sense of urgency and enthusiasm to others. If a leader can't get a message across clearly and motivate others to act on it, then having a message doesn't even matter." Gilbert Amelio, former President and CEO of National Semiconductor Corp. If a leader do not communicate well with people, people would not able to understand him and will not be able of doing the correct things on time. It will the same as the leader not passing down the message. so the leaders must need to know about their team member, and how to communicate with them easily. And know how to motivate his people while sending the message across. Also setting a deadline to suit the members ability and project deadline.

 Subject: Self-Introduction Letter Dear Professor Blackstone, I am writing with an intent of introducing myself to you. My name is Lim Heng Kiat, I am currently an (RSE) Robotics systems engineering student studying in (SIT) Singapore Institute of Technology. As compared to people of the same age group educations, I had come by a long way route. I did not successfully pass the o levels examinations, so I had to go through institute of technical education for my Higher Nitec study as a mechatronics engineer, afterwards I went to have my diploma educations in Singapore polytechnic as a mechatronics robotics engineer. When I was young, I had watched a few movies and series which story about how AI robots interact with humans which pique my curiosity on actually building my own AI robots. Therefore, it inspires me to join mechatronics and robotics courses to move closer building my own AI human size robots. The weakness of my communications skills is that I lack of confidence in speaking,

The article “NASA’s Self-Driving Perseverance Mars Rover ‘Takes the Wheel’” (2021) highlights the capability of the Perseverance rover's navigation system which is used to traverse on the Martian surface for signs of ancient life along with locating and transporting sample collections of rock back to Earth for analysis. The navigation system consists of Auto navigation system, where it can build 3D mapping of the terrain, identifying the hazards and planning a route around obstacles automatically, Inertial Measurement Unit, which provides 3-axis information on its position like the vertical, horizontal, and side-to-side (yaw) movements, Navcam, two colour stereo Navigation Cameras which typically take wide angle photographs that are used to plan the next moves of the vehicle or object tracking, Hazard Camera, which is mounted on the rover body four on the front and two on the rear, the cameras which it is able to capture 3D views of the surrounding is used for detecting hazards to
