What is the disadvantage in remotely operated underwater robot?
Water
An increasing number of hobbyists, institutions and companies are developing unmanned underwater vehicles. There are many obstacles yet to overcome to make underwater robots attractive to the wider robotic community though in recent years, several companies have commercialized pool cleaning "robots". Underwater vehicles can use ballast (compressed air and flooded compartments), thrusters, tail and fins or even wings to submerge. Other aquatic robots such as pool cleaners are useful commercial products.
Advantages- Most of our planet is water, so there is a lot to explore and discover
- Design is almost guaranteed to be unique
- Can be used and/or tested in a pool
- Robot can be lost many ways (sinking, leaking, entangled…)
- Most electronic parts do not like water (also consider water falling on electronics when accessing the robot after a dive)
- Surpassing depths of 10m or more can require significant research and investment
- Very limited robotic community to provide help
- Limited wireless communication options
What are the disadvantages of humanoid robot?
Fine motor control. Basically the use of hands and walking. Walking is way more difficult than it feels, especially in a big clunky machine. Robots at this point just don't move as fluidly as we do.
What is a scientist called that studies and develops robots?
I do not know if there is a name for it, but I know that most people who go into robotics are engineers.
What limitations do you think should be placed on the use of robots?
many limitations should be placed on robots because robots may fail when you can rely on humons to sit down and figure out the problem
Robots are still very basic machines and started in industry and factories. Robot type machines have been in use in building cars since the late 1970's. Japan has made several early prototype robots that do minor things, but has yet to produce one for that does more than move a bit and say one or two words. It will take time before we have a true human working type robot.
What are the materials needed to make a robot?
Generally:
- Some kind of controller (such as a computer, microcontroller or PLC)
- Servos and actuators (as needed for the tasks of the automated device)
- Assorted gears, cables, relays, sensors
- Some kind of power supply; typically a battery
- Other electronic devices as deemed necessary, such as IC chips, diodes, UARTS or other communication chips, RF controllers
- And anything else you can dream up that might be useful in the robot you're trying to build.
Good luck; robotics can be a fun and enjoyable hobby.The most fun is when you dig into the controller and figure out how to make your robot accomplish the tasks that you want it to perform. Programming your robot can be both challenging and rewarding.
What is the formula for diameter radius circumference?
Radius is the distance from the outside of the circle to the center.
Diameter is the distance ACROSS the circle, it's formula is:
D = 2R (Diameter is 2 times the Radius)
Circumference is the distance AROUND the circle.
C = Pi D, where Pi is the constant 3.1415.... (look it up))
What is the process of making a robot?
Generally robots r the tools for making things easier in our daily lifes. Generally concept of robots derived from computers. As computer robots has its own software which helps us to communicate, make them obtain human functionality.
How do you make a robot that does your homework?
First, you have to do your homework so that you can understand the important subjects, such as math, physics, metallurgy... then you should go on to computer science, and electronics where you can learn about micro-controllers, actuators, sensors, stepper motors, data communications and other related subjects.
THEN, once you have a good understanding of computers, AND physics, you might be able to build a robot that can do your homework... but it all seems a little pointless by then.
because million years ago there was many robot there so they made it with metals and alecticity and light
What are the positive effects using robots?
Robots (in terms of machines designed to carry out certain physical tasks) can provide a wide variety of benefits to society. The most prominent benefit of robots is that they allow physical tasks to be performed at a greater speed than humans could reasonably achieve, and that tasks can be performed by robots that are beyond the reasonable physical capabilities of humans.
For example, in manufacturing, mechanised processes allow production to take place at a great speed, with little human effort required. This allows for the low-cost mass-production of goods. These manufacturing processes allow for great precision, and can allow products of a very high quality to be produced. for instance a little girl age of 6 was in a car crash & lost her leg, but robotics was there & saved her lost leg
What are the positive and negative effects of using robots?
Positive : makes life easier negative : makes us lazy
What sensors does the robot have?
The sensors that an engineer puts on a robot are entirely dependent upon the functions that the engineer perceives that the the robot will be called upon to perform.
Some, but not all, of the sensors may be:
proximity sensors,
pressure sensors,
light sensors,
magnetic sensors,
a camera,
temperature sensors,
accelerometer,
speed sensor...
The question isn't, "what sensors does a robot have", but rather, "what sensors does the engineer think that the robot should have?"
Why is a robot a robot and a human a human?
The differences between robots and humans include:
- Humans have a biological form; robots do not.
- Humans have living tissue that makes up skin, muscles, tendons, ligaments, bones, joints, blood, and all organs including the brain; robots do not.
- Humans are born after 9 months of being carried and nourished in a female human's uterus; Robots are constructed (built).
- Human infants can see, hear, smell, taste, and touch within the womb and can use these senses from birth, even though eyesight is poor at birth; robots cannot.
- Humans have instinctual knowledge from birth; robots do not.
- Humans begin learning from the moment of birth; robots must wait until the last piece of hardware and last portion of software are active, and can only "learn" if that is part of their programming.
- Humans move in a variety of ways and because of the biological make up can twist, turn, sit, lay, walk, run, jump, climb, and -- scratch; robots do not easily move and do not have the neuro-muscular control that humans have so robots cannot perform all the movements that a human can do.
- Robots do not feel sensations (heat, cold, itching, etc.) so they will not respond to surface sensory stimuli; a human will scratch an itch, rub an area of skin that is cold, etc.
- Humans have sweat glands; robots don't.
- Humans have reproductive organs; robots don't, so they can never bear their own young.
- Humans have hormones and emotions that act together to make humans want to have sex; robots don't have any sexual urges.
- Humans need and seek love; Robots can exist without both.
- Robots may be able to preform mathematical calculations faster, but robots cannot discuss, explain, or defend their answers. These are higher functioning skills within the human brain.
- Robots will never know the "gray area" of decision-making, whereas humans must make decisions between "not so bad" and "not so good" every day.
- Robots can never experience loss-- whether of self or someone else. For example, a victim of a car accident may lose a leg and grieves that loss, but a robot wouldn't react if its leg was removed. A mother will grieve for years after the death of her child, but the death would not phase a robot.
- Robots cannot know the pressure and drive behind hopes and dreams. A human, though, can hold onto a hope or dream for decades, and repeatedly seek ways to make that hope or dream a reality.
- Robots can help humans do some tasks faster, but a robot can never fall in love or fall in love as fast as a human can.
There's likely more to add, but these points are key.
How is the robot taught to perform its task?
Programming of most current robots is performed using basic instructions such as:
- Raise control arm to index (find out where you are)
- Open manipulator fingers to index (find out where you are)
- Turn motor shaft clockwise to index point (find out where you are)
- Turn motor shaft counter-clockwise 35 pulses of the encoder. (correlates with a specific angle)
- Lower control arm until resistance is detected on manipulator 'down' pressure switch.
- close manipulator fingers until fingertip pressure detector detects resistance.
- Raise control arm to index.
- turn motor shaft clockwise an additional 70 pulses of the encoder...
These types of basic motions will vary from one robot to another, and can be grouped together into "routines", allowing the engineer to "call" a specific task rather than program the entire set every time.
Robots do not learn by watching someone perform the task.
Another way that a robot can "learn" a task would be for the engineer to physically move a robot through a specific task, using something like a "joy stick" and instructing the robot to store the moves for later repetition; but in that case, the robot would simply be storing instructions similar to what is described above.
