- On statistical analysis of biological armsPublication . Galhano, Alexandra; Carvalho, J. L. Martins de; Tenreiro Machado, J. A.The statistical analysis of robot manipulators reveals the limitations of joint-actuated machines. Steming from the results, in this paper we apply the statistical concepts on the study of biological arms. The superior performances of muscle-actuated arms over standard joint-actuated manipulators are demonstrated.
- On statistical analysis of mechanical manipulatorsPublication . Galhano, Alexandra; Carvalho, J. L. Martins de; Tenreiro Machado, J. A.A novel approach to the modelling of manipulators is presented. Usually, system descriptions are based on differential equations which lead to very precise results but need laborious computations. The statistical modelling overcomes these problems and gives clear guidelines towards performance optimization.
