FORWARD WALKING TEST - ANALYSIS
The charts below graphically display the results of the straight line walking test for the Robonova-1 and the I-Sobot.
If the robots wandered to their right, the amount is shown as a positive amount, and wandering to their left is a
negative amount. The fact that there is not a clear pattern indicates that our test platform is close to level, and our
home position on the robots are reasonable. In a shocking coincidence, for Test 15 on the Robonova-1 and Test 4
on the I-Sobot the robots landed exactly on the center line. If you watch the videos for these tests, you will see that
it is a random event. Remember, we did not make any course corrections during the tests.

It was not a surprise to see there is a strong correlation between the number of steps the robot took, and the time necessary to complete the
test, as shown below. The bigger surprise is that the variance from center is not strongly correlated to the time necessary to complete the test.
test, as shown below. The bigger surprise is that the variance from center is not strongly correlated to the time necessary to complete the test.
What we learned from this is that each robot took roughly the same number of steps to complete the test, but the I-Sobot was twice as
fast. This means that each robot has roughly the same length of each step (relative to its body height), but the I-Sobot was able to
perform so much better because it has a continuous walking motion.
180 DEGREE TURN - ANALYSIS
The charts below show the variance side-to-side against the variance front-to-back for our Human subject, the Robonova-1 and the
I-Sobot. The chart on the left shows the raw results measured in inches. Since the Robonova-1 is so much smaller than the Human, you
would expect the variance to be smaller, and the I-Sobot is even smaller. Therefore we have also included the variance as measured by
the % of Body Height in the chart on the right. So when the Human attempted to turn 180 degrees, it took about 23% of its Body Height,
but the Robonova-1 required a whopping 72.8% of its Body Height to make the same move, or roughly 3 times worse. The I-Sobot gave
similar results requiring 73.3% of its Body Height to turn 180 Degrees. The chart on the right graphically displays the performance
difference based on the lack of rotation at the hip or waist for the Robonova-1 and the I-Sobot. We plan to test other robots in the future
which have hip rotation so that we can measure how much better the performance really is.
