Hexapode

He,
I would like to buy Allbot, but I would like to create a 6-leg version with three degrees of freedom. If I buy the kit, I have 4 legs for 2 servo, so I have to buy 6-legs for 3 servo kits without using the previous ones. It’s right? And I would also like to know if the various software and scretch for Arduino allow me to move the exapode robot , without any programming.
Thanks
