Comparison of motion between opposite points for (a) typical industrial arm, and (b) typical laboratory armReTiSoft is a software research and development enterprise based in Mississauga, Canada. The company is a provider of turnkey and custom automated systems for the pharmaceutical, biotechnology, and research industries. ReTiSoft software is used to control and schedule the movements of a robotic arm as it transports microplates and vials between pre-programmed stations (nests), in order to automate laboratory experiments.  A problem arose when attempting to integrate an industrial robotic arm, namely the Stäubli TX-40, as opposed to the typical laboratory arms with which ReTiSoft previously dealt. The Stäubli TX-40 robotic arm functions differently from the regular robotic arms designed for moving resources in a laboratory environment as shown in Figure 1. The industrial robotic arm had no firmware of its own and the programming environment supplied with the arm was very limited.

Maciej Makowski, a co-op student from the University of Waterloo, was asked to develop a device driver for this new industrial robotic arm.
