  Perseverance’s Robotic Arm Summary The webpage “Robotic Arm” (NASA, n.d.) introduces Mars' Perseverance’s robotic arm. The robotic arm collects rock samples and stores them for analysis. The Perseverance’s robotic arm consists of scientific cameras, a drill, Gaseous Dust Rem oval Tool (GDRT), five degrees of freedom rotary actuators and a ground contact sensor.  There are three scientific cameras, WATSON, SHERLOC and PIXL. As mentioned in the webpage “Watson” (NASA, n.d.), WATSON is a color camera used to take zoomed in pictures of targets of interest that contain signs of microbial life searched by SHERLOC. PIXL functions similarly to SHERLOC. However, it is able to identify chemical elements at a miniscule level. The rover's drill penetrates into the Martian surface to collect and store rock samples according to “Robotic Arm” (NASA, n.d.). The GDRT  then uses nitrogen gas to reveal the inner layer of the rock for analysis (Brockie, 2021).The five degrees of freedom ro...

  The Perseverance’s robotic arm consists of scientific cameras, a drill and a ground contact sensor. There are three scientific cameras. WATSON is a color camera used to take zoomed in pictures of targets of interest (WATSON, n.d.) that contain signs of microbial life searched by SHERLOC (SHERLOC, n.d.). PIXL functions similarly to SHERLOC. However, it is able to identify chemical elements at a miniscule level (PIXL, n.d.). The rover's drill penetrates into the Martian surface to collect rock samples. The drill is equipped with three different kinds of bits that help collect samples. The coring and regolith bits contain sample collection tubes to store samples when drilling. The abrader bit is used to remove the eroded surface layer of rocks, to reveal the inner layer of the rock for analysis (Robotic Arm, n.d.). The ground contact sensor sends a signal to the robotic arm to stop its movement to prevent it from touching the ground (Robotic Arm, n.d.). References: WATSON  (n.d...

Subject: Self-introduction letter  Dear Professor Blackstone, My name is Dillon Chew and I am writing this letter to introduce myself. I am currently a year one student from the Robotics Systems Engineering programme in Singapore Institute of Technology. I previously graduated with a Diploma in Mechatronics and Robotics from Singapore Polytechnic.  Even though I had decided to specialize in the field of robotics before entering polytechnic, it was not something I particularly had an interest in. It was only much later in my final year my interest in robotics sparked. I used to think that all the math and physics I was learning was pointless and had no real world applications. However, that all changed as I started my final year project.  For my final year project in polytechnic, I was tasked to create an autonomous vehicle, the purpose of which was to transport people from one place to another within the airport's premises while concurrently avoiding other people and obst...

 How do I see communication and critical thinking impacting my role as a leader in my future workplace?  Great communication skills would allow me to be able to pass down information or ideas clearly and concisely to my team members and critical thinking would allow me to find logical solutions to problems faced based on data and research.   As someone who has worked in the government sector before, I have witnessed firsthand what implications poor communication can have especially when it involves people from different ministries working together. A breakdown in communication causes confusion which leads to more problems and more time spent trying to solve them. It could also lead to unhappiness and distrust among all parties involved which could lead to further communication breakdowns. Therefore, a great leader must be able to communicate effectively with their team members to eliminate any ambiguities that could lead to further problems.  Communication and c...

  “Employers identify communication as one of the basic competencies every  graduate should have, asserting that the ability to communicate is valuable for  obtaining employment and maintaining successful job performance.”  Sherwyn Morreale, Michael Osborn & Judy Pearson,   -Professors of Communication (2000) Without proficient communication skills, there can be miscommunications as well as misunderstandings not only among colleagues but also with one's superior. With big projects where many professionals from different fields of study work together, a lapse in communication may cause unforeseen mishaps that could be disastrous if commercially distributed.
