13. Speed Control of an Autonomous Mobile Robot: Comparison between a PID Control and a Control Using Fuzzy Logic
An Autonomous Mobile Robot battery driven, with two traction wheels and a steering wheel is being developed. This Robot central control is regulated by an IPC, which controls every function of security, steering, positioning localization and driving. Each traction wheel is operated by a DC motor with independent control system. This system is made up of a ch

14. Oclusor ativo implantavel para colostomias : prototipo
: Aiming to improve the quality of life of colostomates, the prototype of na Active Implantable Colostomy Occluder was built. The fundamental idea is to reproduce the natural sphincter?s action by using a construction band placed around the stoma and pulled by a step motor. The active element of the prototype is a step motor and its torque is powered by thre

15. Analise do comportamento dinamico de um veiculo automotivo
The theoretical dynamical behaviour of a four wheel car model is analysed. The physical model with seven degrees of freedom is chosen and after some simplifications the corresponding mathematical model is established. First is studied the dynamical eigenbehaviour of the model for both unloaded and loaded conditions through the obtention of the eigenvalues an

16. Sudden Illness as a Cause of Motor-vehicle Accidents
Forty-one of the 44,255 road accidents reported to the police in one region of Sweden during 1959-63 were, or probably were, caused by sudden illness in the driver of a motor-vehicle. All 41 were males. The illness was most often due to epilepsy or myocardial infarction. Eight drivers died at the wheel from their disease. No other persons were killed in the
