Abstract
This paper focuses on using the Bees Algorithm for optimising the parameters of the swing-up control for a robot gymnast (Robogymnast) attached to a freely rotating high bar mounted on ball bearings. Robogymnast, which mimics a human acrobat, consists of three links and three joints. Its motion is manipulated by two DC motors mounted at the shoulders and hip joints. The freely rotating high bar represents the third joint to which link 1 (hands and arms as a single rigid part) is firmly attached. Although, this triple pendulum-like structure is difficult to balance at upright posture, its unpowered joint is advantageous during the swing-up phase. The ultimate challenge was to smoothly swing up Robogymnast from the downward (stable) position to the upright (unstable) configuration by finding optimum values of the parameters that regulate the amplitudes and frequencies of the sinusoidal signals applied to the two DC motors. The Bees Algorithm was used as an optimization technique to achieve this. From the randomly obtained set of parameter values, three were selected to simulate the behavior of Robogymnast during the swing-up phase. The results showed successful swing-up of Robogymnast.
