DESIGNING AND CONTROLLING INDUSTRIAL ROBOTS INVOLVES DETERMINING THE POSITION OF ITS KINEMATIC CHAINS IN RELATION TO A FIXED COORDINATE SYSTEM – THE ABSOLUTE POSITION OF THE ELEMENTS AND THE RELATIVE POSITION – REVEALED BY GENERALIZED COORDINATES. MOST OF THE WORK AVAILABLE REGARDING THIS ISSUE IS BASED ON DIRECT KINEMATICS USING THE DENAVIT -HARTE…
MODELING THE FORWARD KINEMATICS FOR ROBOTS THAT INCLUDE CLOSE KINEMATIC CHAIN STRUCTURES IS DIFFICULT. WHEN DENAVIT -HARTENBER (DH) FORMALISM IS APPLIED, USUALLY IT COMES TO A SIMPLER KINEMATIC MODEL THAT DOES NOT ALWAYS CORRESPOND WITH THE REALITY. IF MORE THAN SIMPLY KNOWING THE END EFFECTOR POSITION IS DESIRED, SUCH AS KNOWING THE POSITION OF TH…
THIS PAPER PRESENTS THE DESIGN AND FUNCTIONAL STUDY OF THE PROTOTYPE OF A MULTI - ROTOR (HEXAROTOR) DRONE AND SUBSEQUENTLY OF ITS ACTUAL PROTOTYPE REALIZATION.
