STE 58762 － － 1-3 1.2 ROBOT LANGUAGE Robots do assembly work and other tasks in place of people. However , someone still has to teach the robot what to do. Robots will only do what you tell them to do, and it's important to tell them exactly what you want it to do. T elling a robot what to do is called "teaching." Making a robot [...]

STE 58762 － － 1-4 If we were to write a program in SCOL for the previous example (in which we attach a part from a parts feeder to a workpiece on a co nveyor), it would look like this: PROGRAM ASSEMBL Y MOVE B Move to Point B.

STE 58762 － － 2-5 2.4 V ARIABLES AND CONST ANTS Not all data takes the same form, and these different forms of data are called data types. S calar type (integer type, r eal number type and characte r string) and vector type (po sition type, coordinate type and load type) can be used in the SCOL language. V ariables ar e divided into global vari[...]

STE 58762 － － 2-6 (b) V ariables V ariable s are distinguished by identifiers and can be in the range of - 2147483648 to + ~147483647, just as above. Th e data type of a variable is determined by th e data type of the first number you assign to that variable. For example, if the first thing you assign to a var iable is an integer , all other nu[...]

Th e data are not created in the file. The vector type variable can b e used only in the declared program. Thus , even if the same variable is used in another progr[...]

STE 58762 － － 2-9 What we did above was take an original coo rdinate system (centere d about 0), applied a coordinate vector (x, y , z , c) to it, and came up with a new coor dinate system (centered about 0' ). In short, coordinate vectors allow us to conver t between different coordinate systems. Fig. 2.1 Coordinate transformation (3) Loa[...]

STE 58762 － － 2-10 2.4.3 System V ariables The SCOL language provides special variables that are used in the programs to specify and referent robot operating conditions. These variables are called system variables. Just like other variables, you can re fer to these variables in the pro gram, change their value, etc. However , you have to be car[...]
