Distance per Rotation incorrect for Rembot RVW
Hi, I was trying to formulate interesting problem statement for school kids based on Ratios and Proportions. The idea was to move the different virtual bots for exactly 1 rotation on the distance utility and derive PI from that
Now when I tried it on the metric Distance Utility table, Found this interesting output:

Rembot wheel radius = 2.25cm
Calculated Distance for Rembot = 2 * PI * r = 14.13cm...(approx)
Actual Rembot = 20cm
Buggybot wheel radius = 2.75cm
Distance for buggybot = 17.27cm...(approx)
Actual buggy bot = 18cm (approx) acceptable

Mammalbot wheel radius = 3.25cm
Distance for Mammalbot = 20.42...(approx)
Actual for Mamalbot = 22cm (approx) acceptable

Thanks for the feedback! I'll check it out and we'll make adjustments the next time we release an update.

Thanks jbflot
Also, see if the start points can be made to coincide with 0 (zero) for all the robots in Utility tables. Currently there are slight offsets.
