Line 13:

Go to Jig1

is an instruction to the robot to go to positional data named Jig1. Of course, programs can also contain implicit data for example

Tell axis 1 move 30 degrees.

Due to the highly [[Proprietary software|proprietary]] nature of robot [[software]], most manufacturers of robot hardware also provide their own software. While this is not unusual in other automated [[control systems]], the lack of standardization of programming methods for robots does pose certain challenges. For example, there are over 30 different manufacturers of [[industrial robots]], so there are also 30 different robot programming languages required. There are enough similarities between the different robots that it is possible to gain a broad-based understanding of robot programming without having to learn each manufacturer's proprietary language.<ref>{{Cite news|url=http://coro.etsmtl.ca/blog/?p=529|title=The future of robot off-line programming|date=2015-10-25|newspaper=CoRo Blog|access-date=2017-01-03}}</ref>

One method of controlling robots from multiple manufacturers is to use a [[Post processor]] and [[Off-line programming (robotics)]] software. With this method, it is possible to handle brand-specific robot programming language from a universal programming language, such as [[Python (programming language)]].<ref>{{Cite web|url=https://www.robodk.com/offline-programming|title=Offline programming - RoboDK|last=RoboDK|website=www.robodk.com|access-date=2017-01-03}}</ref> however, compiling and uploading fixed off-line code to a robot controller doesn't allow the robotic system to be state aware, so it cannot adapt it'sits motion and recover as the environment changes. Unified real-time adaptive control for any robot is currently possible with a few different third-party tools.

Some examples of published robot programming languages are shown below.

Line 94:

(With Roboforth you can specify approach positions for places so you do not need P2 and P4.)

Clearly, the robot should not continue the next move until the gripper is completely closed. Confirmation or allowed time is implicit in the above examples of CLOSEI and GRIP whereas the On vacuum command requires a time delay to ensure satisfactory suction.

===Visual programming language===

The [[LEGO Mindstorms EV3]] programming language is a simple language for its users to interact with. It is a graphical user interface (GUI) written with [[LabVIEW]]. The approach is to start with the program rather than the data. The program is constructed by dragging icons into the program area and adding or inserting into the sequence. For each icon, you then specify the parameters (data). For example, for the motor drive icon you specify which motors and by how much they move. When the program is written it is downloaded into the Lego NXT 'brick' (microcontroller) for test.
