Drilling a square hole (Cross section of the drill is Reuleaux triangle)
Reuleaux triangle is rotated around its center of gravity, and the center of gravity
moves around the center openings.

Drilling accurate (without rounding) square hole
The disc in the form of a modified Reuleaux triangle
moves inside a square frame . A drill (green dot in the center
of the yellow circle) makes an exact square hole.

2. All three wheels are passive and the part of the rocker-bogie mechanism body is pulled
up by the external force as in the case of shopping carts.

Animation spatial mechanisms
To calculate the position of the mechanism will use
techniques developed A.B.Ivanov.His work on 3d
animation mechanisms made in Mapl, publishes A.B.Ivanov
online
http://forum.exponenta.ru/viewtopic.php?t=12842
Of the examples from this site I suffered in a programming environment SMath Studio
1. Sarrus linkage 1

Nice job ber, as usual
BTW I can't download the first animation (Sarrus linkage 1)
Best regards,
Davide

If you like my plugins please consider to support the program buying a license; for personal contributions to me: paypal.me/dcprojects
Thank you,Davide,now you can download the file.
