Maybe like this ?
The idea is to move a system composed by 2 masses m and 2m without external force. Use only one gyroscope. The gyroscope retrieve 0.5 m at 2m and add 0.5 at m, like that we have a system composed with 1.5 m at right and at left. We can Turn the system m/2m at the center CG with the CG exactly between m and 2m (it's symetrical because the system see only 1.5 m and 1.5 m not 2m and m).
Cycle :
1/ We apply forces red/pink
2/ We turn the system m/2m at CG = Cg2
3/ We stop forces red/pink
4/ We turn the system m/2m at CG = Cg1
5/ Repeat the cycle.
Think with mass of gyroscope = 0 like that it's easier to understand.
