What ANSI safety color is used for "Danger" signs that warn of hazards likely to cause death or serious injury?
What is Red
What is a robotic manipulator more commonly called?
Robot arm (robotic arm or manipulator)
What does OSHA stand for?
Occupational Safety and Health Administration
What are the four colored sections of the NFPA hazard diamond?
Blue (health), Red (flammability), Yellow (reactivity/instability), White (special/specific hazards)
Name a robot type that moves along x, y, and z axes in straight lines.
Cartesian (also called rectangular or gantry)
Which ANSI color identifies dangerous machines or equipment that may crush, cut, or shock workers (used on "Warning" signs)?
What is Orange
Name two common actions industrial robots perform in manufacturing (two short answers).
Examples: Welding, painting, assembly, pick-and-place, packaging, palletizing, inspection, material handling, testing. (Any two)
Is OSHA a law-making agency or an agency that enforces workplace safety standards? (Answer briefly)
OSHA enforces workplace safety standards (it is a regulatory/enforcement agency)
Which colored diamond indicates flammability?
What is Red?
Which robot type has at least three rotary joints and can move like a human arm?
Articulated robot
Which ANSI color is used to point out first aid kits, emergency eye wash fountains, and other medical equipment?
What is Green?
List three types of robot arms (give any three from the unit)
Examples: Cartesian, SCARA, Articulated, Polar (Spherical), Cylindrical, Parallel (any three)
Name one required element of an Emergency Action Plan (EAP)
Examples: Means of reporting fires/emergencies; evacuation procedures and escape routes; procedures to account for all employees after evacuation; rescue and medical duties; names or job titles of persons to contact for information. (Any one is acceptable.)
What does a '4' in the blue (health) diamond mean?
A '4' in blue means the substance can be fatal or cause severe injury on very short exposure.
Which robot type often uses multiple limbs to support a single end effector and is used for very fast pick-and-place?
Parallel robot (often seen as Delta robots)
Which ANSI safety color communicates information unrelated to personal injuries and is commonly used for maintenance notices?
What is Blue?
What is inertia and why must engineers consider it when designing robot motion? (Short explanation)
Inertia is the tendency of an object to keep doing what it is doing (stay still or keep moving). Engineers must consider it because heavy parts resist changes in motion; without proper motors, brakes, and programming a robot could overshoot, swing dangerously, or cause accidents.
True or False: OSHA standards are suggestions only and not legally enforceable.
False — OSHA standards are legally enforceable
What type of information is shown in the white (bottom) diamond (give two examples of symbols or codes found there)?
The white diamond shows special hazards using symbols or letters, for example: "OX" for oxidizer, "W" with a line through it meaning "use no water", and symbols for flammable or compressed gas.
Give one industry and one application well suited to SCARA robots.
Industry: Electronics or packaging; Application: High-speed pick-and-place or assembly of small parts (SCARA are fast and precise horizontally).
What two colors are most commonly used for guiding traffic and housekeeping information in a facility?
What is Black and White?
Describe the difference between Cartesian (rectangular) and polar (spherical) robot work envelopes in one or two sentences.
Cartesian robots move in straight lines along x, y, and z axes producing a rectangular work envelope; polar robots rotate about joints and move in/out producing a spherical (or polar) work envelope that reaches widely but with different motion paths.
OSHA was established under an act signed into law in which year? (Provide the year.)
1970
Explain why emergency responders look at the NFPA diamond on a vehicle or building before they act.
Because the diamond quickly tells responders the health, fire, and reactivity risks plus special hazards, so they can choose safe procedures, protective gear, and firefighting methods before entering the scene.
Compare cylindrical and polar robots: give one key motion difference and one application unique to each.
Cylindrical robots rotate about a base and move linearly in/out and up/down (good for simple assembly or spot welding of cylindrical parts). Polar robots rotate about head and base and move in/out to create a spherical reach (good for handling large or bulky objects like diecasting parts).
