Walk-Through Programming : (Previous)(Better)
The teacher physically moves the robot through the desired position within the robot's working envelope. During this time, the robot's controller may scan and store coordinate values on a fixed time interval basis. These values and other functional information are replayed in the automatic mode. This may be at a different speed than that used in the walk-trough.
This type of walk-through programming uses triggers on manual handles that move the robot. When the trigger is depressed the controller remembers the position. The controller would than generate the movement between these points when the program is played. The walk-trough method of programming require the teacher to be within the robot's working envelope with the robot's controller energized at least in the position sensors. This may also require that safeguarding devices be deactivated. (A.K. Gupta, S.K.Arora, Industrial automation and robotics, Laxmi Pub. 2007, p.324-325)

Walk-Through Programming : (New)(Robot Programming Method)
In this Method, the programmer manually moves the robot's arm and hand through the motion sequence of the work cycle. Each movement is recorded into memory for subsequent playback during production. The speed with which the movements are performed can be controlled independently so that the programmer does not have to worry about the cycle time during the walkthrough. The main concern is getting the position sequence correct. The walkthrough method would be appropriate for sprey painting and are welding robots.

Automatically Programmed Tool (APT) : (Previous)
APT uses English-like language statements to define part shape and tool motion as well as machine tool dependent data, such as feed rates and spindle speeds. This data is contained in an
APT part program. An APT processor program is used to read these statements, interpret the meaning, and perform all the necessary calculations in order to generate a series of cutter
location points that define the cutter path. The APT processors a computer program which
runs on a mainframe computer, possibly at a central site with time-sharing facilities. The
generalized APT output is converted to the particular format G-Code required by the CNC machineusing a postprocessor program.

Automatically Programmed Tool (APT) : (New) (Better) (Computer Language,Programme)
Like any other high-level language, APT allows arithmetic operations, subroutines, macros looping logic, etc. However, the main difference is that it allows parametric representations of geometric entities ranging from a sigle point in space to very complex three dimensional sculptured surfaces. The tool path is generated by commanding the given tool geometry to travel in a selected tool path on the defined part geometri. The computed tool path coordinates and cutting conditions are then stored in a computer file with a general standart format, wich is also automatically converted to the specific manual code of the selected CNC machine tool.
