Robots with telescoping arms are sometimes used to perform tasks (e. g., welding or placing screws) where access may be difficult for other robotic types. during a test run, a robot arm is programmed to extend according to the relationship r = 3 + 0.5cos(4θ) and the arm rotates according to the relationship θ=−π4t2+πt , where r is in feet, θ is in radians, and t is in seconds. use a computer program to plot the path of tip a in x and y coordinates for 0 ≤ t ≤ 4s.

All of the following are characteristics that must be contained in any knowledge representation scheme except

What statement best describes operating systems? it’s possible for modern computers to function without operating systems. most operating systems are free or very inexpensive. operating systems are managed by the computer’s microprocessor (cpu). operating systems manage the computer’s random access memory (ram).
