A robot with computer vision could easily tell apart maize from soy from squash (different colors, react under polarized light differently, leaf size, plant structure, etc). The real problem is that 1. squash has limited commercial value. 2. corn grows to 8' tall while soy is only a couple feet. The corn would block all the sun from the soy. When you plan a field full of corn it all grows at a uniform rate so each stalk gets an even amount of sun, rain. If you want the advantage of both crops, you rotate every year or two. That way the soy can perform nitrogen fixation with various bacteria and produced essentially free nitrogen fertilizer for your corn.
