Published Online: September 11, 2019
Fig. 5 Determinant and orientation of total impedance ( Z ), stiffness ( K ), and damping ( B ) ellipses at the frequency of the movement ( f = 0.125 Hz). The orientation of the ellipses is calculated considering the major axis at 0 deg when aligned in the x direction as illustrated in Fig. 1 ... More

Fig. 6 Ellipses representation for the different components of arm mechanics. M represents the average ellipse of inertia (dashed). The dotted ellipses represent those obtained with the two methods that tend to overestimate (HV) or underestimate (PI) the bulk of inertial properties [ 53 ]. Inertia... More

Published Online: September 11, 2019
Fig. 9 Stiffness features of the experimental apparatus. Each coefficient estimation presents a small drift, which is never bigger than ±2.7%. Estimations of the stiffness metrics also present some drift, but do not have a preferential direction. More
