Figure 5. Robot's biological vs. non-biological kinematics.

Figure 5

A) robot's biological (BIO, continuous line) and non-biological (NBIO, dashed line) velocity profiles are represented for the three movement velocities. While in BIO the deceleration phase started when the maximum of velocity was reached, in NBIO, after the initial acceleration phase, the velocity profile reached a maximum that was kept approximately constant for a minimum of 1 s, followed by a deceleration phase. B) Participants' mean velocity (VP, y-axis) as function of the robot's velocities (VR, x-axis) (mean±SE). Full and empty triangles refer to BIO and NBIO robot movement kinematics, respectively. Continuous and dashed traces are the regression lines which model VP and VR relationships in BIO and NBIO, respectively.
