Our robot hit 110 lbs on a very old bathroom scale today, which is almost exactly what our CAD said. We plan to acquire a better scale, but we had some people with known weights "calibrate" that one. Our structure is pretty simple but is mostly heavy 2x1x.125" tubing and we're using all 6 CIMs, 4 miniCIMs, and a pair of AM 9015s on the PG-71 gearboxes (no, we don't plan to pop the breaker every match
)
The tubing is mostly solid so we may try to make some sort of jig to swiss cheese our unbagged parts. Life would probably have been much easier if we used the thinner Vex tubing, but they were out of stock until the day we placed our order. We may also switch out the miniCIMs with banebots motors in versaplanetaries or CIMiles if we can afford it.
