Figure 11.27, the blue line shows the velocity calculated<br />

with the Jacobian matrix, and the red line shows the<br />

reference velocity from EPAS.<br />

Figure 11.28, shows deviation between calculated and<br />

reference velocity. Where the calculated is computed with<br />

the Jacobian.<br />

Figure 11.27 shows the three different arm joint velocities in the unit degree/s over the time in<br />

seconds. To make it easier to see how big the deviation is between the EPAS reference value of<br />

the velocity and with Jacobian matrix calculated velocity Figure 11.28 shows the percentage<br />

deviation between EPAS reference value and with the Jacobian calculated value.<br />

Figure 11.29, the blue line shows the calculated acceleration and the red<br />

line shows the reference acceleration from EPAS.<br />

In Figure 11.29 the blue line represents the calculated joint acceleration for arm 1 of the Delta-<br />

3 robot and the red line describes the reference acceleration in EPAS. If one looks at the joint<br />

velocity of joint 1 there is a smaller percentage deviation (Figure 11.28) between the calculated<br />
