Abstract [sv]

Today Halmstad University is using six robots that are based on a digital signal processor (DSP) from Texas Instrument and an external I/O-card. These robots can today only be programmed by means of conventional programming, i.e. some kind of high level language as for example ANSI-C, which can be difficult for people with less programming skills. The idea of the robots is that they should be used to introduce and get high school students interested in this kind of technique, and that’s why it has to be easier and more intuitive to program them. This report explains how to construct a graphical programming tool, i.e. a tool that involves that the user can place a number of happenings on the screen that he/she wants the robot to perform. The user then links them together in what order he/she wants them to happen. After this the necessary code in ANSI-C is generated by the tool itself, i.e. the user can actually program the robot without really having any programming skill. The tool also automatically compiles, links the generated code, and creates a binary file, which later can be downloaded to the robot. The user can within the tool add, delete and move different objects (happenings), e.g. run engine 1 with a certain speed, read the value of digital and analog inputs etc. It is also possible to dynamically increase the functionality of the tool by simply adding new features, which is powerful if you for example want to use the tool on different robot platforms. The functionality is tested on a real robot equipped with two DC-engines and two digital sensors. The result shows that both the code generated by the program is correct as well as the generated binary file, i.e. the compiling, linking and downloading stages work correctly.
