My tactics;
Panic! I didn't plan on coming across a cluster! I will have to take each one in one at a time, hopefully I will be able to grab each part of the cluster when it comes to attack or pull in one of the other robots not currently attacking me using my kyoketsu-shoge. Once grabbed I will give them a quick couple of hits with my hammer to hopefully break them as they should be quite weak and I could snap the gimson axles. If that doesn't work dump them in the pit using my more powerful drive, all I need to do is destroy half of the clusters.
