Variable Assembly Language

Variable Algorithmic Language (VAL) is a <a href="/facts/Computer/SQe1aK05">computer</a>-based <a href="/facts/Control_system/8CEjIDlS">control system</a> and language designed specifically for use with <a href="/facts/Unimation/8CHoN0hh">Unimation Inc.</a> industrial robots.
The VAL <a href="/facts/Robot/S5mDzWYk">robot</a> language is permanently stored as a part of the VAL system. This includes the programming language used to direct the system for individual applications. The VAL language has an easy to understand syntax. It uses a clear, concise, and generally self-explanatory <a href="/facts/Instruction_set/8p8vwUeE">instruction set</a>. All commands and communications with the robot consist of easy to understand word and number sequences. Control programs are written on the same computer that controls the robot. As a <a href="/facts/Real-time_computing/p9HxgL4L">real-time</a> system, VAL's continuous <a href="/facts/Trajectory/STNN33FK">trajectory</a> computation permits complex motions to be executed quickly, with efficient use of system memory and reduction in overall system complexity. The VAL system continuously generates robot control commands, and can simultaneously interact with a human operator, permitting on-line program generation and modification.
A convenient feature or VAL is the ability to use libraries or manipulation routines. Thus, complex operations may be easily and quickly programmed by combining predefined subtasks.
The VAL language consists of monitor commands and program instructions.
The monitor commands are used to prepare the system for execution of user-written programs. Program instructions provide the repertoire necessary to create VAL programs for controlling robot actions.
