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 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.

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?
