There seems to be no significant difference between the robot when whearing weels and when not - there is only a difference of 0.1 between the average readings in the two cases. We concluded that the difference is negligible.

We concluded that the difference is negligible.
It is interesting that the average reading this time (in both cases) was closer to 597 than to 598, as opposed to what we concluded from the preceding run. However, we were not necessarily wrong in our observation as 598 could simply result from that specific testing situation being an extreme with respect to the average.

In both cases the readings fluctuate around the average offset and there does not seem to be a clear drift towards neither upper nor lower values (see Figure 7). If testing for a longer duration of time we might expect to see a drift towards lower values as the average deviation in that direction is larger than towards higher values, in both cases.
