Bio cannon

The bio cannon was a gigantic droid, similar to a droideka and the Galactic Republic Ball Gun, that served essentially as a heavy weapon. It was employed by the Trade Federation. Similar to the droideka and Droideka Mark II, it could roll in an armored sphere form. The design also had four legs to stand on.
The design was similar in function to the SPHA-T, but had less protection.
