are hydraulics or pneumatics more accurate?
from electricity to torque
how do electric dc motor convert energy?
V1=I1R1
how do you calculate voltage drop?
all of the junction should equal the total
how do you figure out how much current goes through each part of a junction?
add all the current parts
how do you find the total current of a battery?
from the base to the end effector
how do you number the 6 axis on a robot?
the amount of electrons flowing through something
what are amps?
name of a variable

once a variable is declared a constant, the number is a literal
what are literals?
its what the operators are affecting ie 3+4=7 3 and 4 are operands
what are operands?

---- --
what does a battery look like?
a squigly line
what does a resistor look like?
hand held device that can program for a robot.
what does a teach pendant do?
to keep humans out of harm's way
what does dangerous mean in why we use robots?
to do tasks that are hard
what does difficult mean in why we use robots?
to help keep humans healthy and to keep sanitary
what does dirty mean in why we use robots?
repetitive tasks that robots can do so humans can focus on human creativity
what does dull mean in why we use robots?
Process
what does this mean?
decision
what does this mean?
input/output
what does this mean?
start/end
what does this mean?
Around any complete loop the total voltage must add to zero. Ohms of resistance also equal total voltage
what is Kirchhoff's voltage law?
an industrial robot that moves well in the x and y coordinates but rigid in the z
what is a SCARA?
looks like a claw but stationary and make a kind of cone envelope i think
what is a delta work envelope?
1. Preparation 2. Shutdown 3. Isolation 4. Lockout/tagout 5. Stored energy check 6. Isolation verification
what is a lock out tag out procedure? (loto)
what performs the action ie for loops, while
what is a statement?
space a robot can move
what is a work envelope?
where code starts
what is an entry point?
when something becomes a value ie const x=5
what is an expression?
electricity flows from positive to negative but in reality electrons flow from negative to positive
what is conventional current?
visually displays the sequence of activities in a process and who is responsible for those activities.
what is the purpose of a flow chart?
a teach pendant
what is this?
parallel circuit
what is this?
series circuit
what is this?
a chemical reaction in a battery that pushes electrons through. voltage is always relative
what is voltage?
base

drive
what part is this?
power source (pneumatic)
what part is this?
work envelope
what part is this?
manipulator
what part is this? (end piece)
on the back of some teach pendants
where are dead man switches located?
industrial revolution lead the capacity to control electricity and eventually small motors were developed in the 20th century
List key events that lead to the invention of the modern robot
An industrial robot is a robot system used for manufacturing. ... Typical applications of robots include welding, painting, assembly, disassembly, pick and place for printed circuit boards, packaging and labeling, palletizing, product inspection, and testing; all accomplished with high endurance, speed, and precision.
What are industrial robots?
V=IR v=voltage I=current - Amps R=resistance - Ω
What is Ohm's Law?
