Photographing the minibots was quite a challenge. They're fast and tiny, sometimes not much wider than the pole. Autofocus is the only thing fast enough to keep up, but it's often confused with what to focus on; the pole, the light at the top, or that barely noticeable blob racing up the pole. My "hit" ratio with minibots was much lower than with all other subjects. I did pick a spot on the pole and prefocus a few times, which worked out better sometimes, but I was often disappointed when the minibot I chose to cover didn't even make it up the pole, and another one next to it did, but I wasn't set up for it.
My suggestion is to shoot a little wider scene, focusing on the top of the pole, and shoot many frames. Also, if you have any leeway in shutter speed, you'll want to overexpose a bit as the meter usually picks up the overhead lights and underexposes the subject.
As for shutter speed, I usually shoot in aperture mode, wide open, and iso as high as I'm comfortable with (1600 ~ 2000), which usually yields an adequate shutter speed. But it's always a compromise. Depending on your lens, you may have to push iso higher and put up with some noise, or even underexpose. But that's just my personal preference. I'd rather see a slightly underexposed, noisy image with no blur, than a correctly exposed blurry one.
