Transcript of Copy of Exploratory Robots Ocean & Space

Exploratory Robots
Oceans and Space By Alexander Stavola, Franklin Speck, Max Triano What They Are Exploratory robots are robots that are designed to be able to access areas that are not possible for humans to access, like outer space, and the deepest parts of the ocean. Tasks They Perform THE END Oceanic Space -Carry scientific instruments for measuring different statistics about the deep sea
-Can withstand pressures and other conditions that humans can't
-Don't need an oxygen supply
-Collect specimens using robotic arms -Can go into space without pricy space suits
-Can stay in space for much longer periods of time than humans can
-Carry scientific instruments that measure different statistics about space
-Can take pictures of stars or planets
-Some are used as telescopes The first exploratory robot to take a dive into the sea was named
Alvin. In Spring 1964, Alvin dove almost 12 meters below the surface of the water. Alvin held three people- this made it a HOV (human-occupied vehicle). Now, ocean exploratory robots can travel 4,500 meters below the surface of water! History of Sea Exploration Robots http://scratch.mit.edu/projects/Assyriaproject123/2765603 Scratch Link: Work Envelope Space robots like satellites don't have any degrees of freedom because they have no moving parts
Robots like the Curiosity rover have a 2.1 meter arm with three flexible joints, and six degrees of freedom
Robots used for deep sea exploration have no degrees of freedom and no moving parts but carry a wide variety of sensors. This robot can be used in careers of space and ocean exploration. It opens jobs of programming the robot. Possible careers Video Link Exploratory Robots have several sensors on them, including light, sound, and touch. The touch sensor is activated if the robot hits something, so it knows where the object is and can turn away. Exploratory robots also carry digital cameras. Rovers like Curiosity have many different instruments that perform tasks such as measure radiation, temperatures, humidity, pressure, and wind speed. Sensors End effector -Is multifunctional
-Is used for:
Picking up rock/soil samples
Detecting obstacles and moving away from them. How the Robot Is Taught to Perform Its Task Exploratory robots do their tasks based on how they are programmed
Programmers must do lots of trial and error before they get their program exactly right The audience of space and sea exploratory robots is usually a group of scientists, astronauts, and deep sea divers. They obtain feedback from people who have actually performed the robots task, which could make it easier to program and, above all, use. The audience would either be impressed, or would have ideas for improvement. Audience Effects Advantages/DisAdvantages Advantages: No humans endangered, no need for breaks/food, robots can perform repetitive tasks that humans would get tired doing

Disadvantages: Robots cannot perform on their own; they need human guidance, most robots cannot perform complicated tasks, robots can be very costly (Curiosity cost $2.5 billion) The possibilities for future alterations are endless; some that might be recommended by astronauts would be smoother movement, better terrain capabilities, and a more compatible end effector. In the sea, the robot would be able to go even deeper than it currently can. Possible Alterations Works Cited
