Abstract

In this position paper we concentrate on one aspect of the robot tasks, its ability to pick up and move heavy loads, far beyond the manufacturer instructions. Such expansions may apply to other tasks, as well. Three approaches to improve manipulators weightlifting ability are suggested: mimicking the Olympic weightlifter’s strategy; weightlifting along the minimal energy trajectory and overloading manipulator's motors. The analytical analysis has been worked out on a simple pendulum. Three optimization methods were compared: calculus of variation, Genetic algorithm, Line-search. Then, the results were demonstrated on a model of the Mitsubishi RV-M2 manipulator. Combination of motor overloading with minimal energy trajectory yielded increase of weightlifting capability 10 times higher than the manufacturer specs.
