I agree. This design looks like it would (a) require significant time for an inexperienced team to build, and (b) not adapt to many Minibots. I much prefer the designs in the
Minibot Standardization thread that have only a few points of contact with the Hostbot. Most of them allow the Minibot to be of any allowable size or shape. (I don’t believe it’s biased that I include my own idea in this, as this was something I considered.)
