Chassis weight

[wilsonmw04]

We did that, sort of. We used a 6-WD with two sets of chains on each side. Without the battery it weighted ~47 lbs. With just the parts in the KOP i bet it's closer to 40 lbs.

Our chassis (non-kitbot, fully custom) with no transmissions or anything is 17lbs. With transmissions and two CIMs total it feels much closer to 35lbs.

We weighed ours with a chassis, 4 wheels, 2 sprockets, 2 gearboxes, and no electronics and it came out around 26 lbs. No battery, only 2 cims. So factor in battery weight and whatever the weight of the electronics panel would be and it probably will run up to around 45 lbs.

If you're thinking about what your robot will weigh fully built, remember that the weight of the battery is not included in your total weight at inspection.

Ours is with battery, electronics board, 2 normal 2 small wheels, 2 gearboxes, I don't remember the sprockets. It is 46 Ibs.

We finished our frame yesterday at 11.5 lbs

Our completely finished uber beefy drivetrain with motors and electronics is right around 50lbs

[midway78224]

our drivetrain when we finish it was at 55 lbs that was with electronics, supershifters, six wheels, etc....

Our frame is 10.75 lbs.

The complete, operational drive train, save 12V battery, is 35 lbs.

How and why do some teams make the drivetrain so light? It would seem that it would hurt the CG a lot.

We make everything as light as possible. Adding weight later is much easier than taking it off. In the ten years that I've been with FIRST, I've had a robot tip over twice.

I'm not sure why zyik deleted her post; It was true. Our frame really is 12 pounds. We use extruded aluminum, not the kit frame.

[sdcantrell56]

Ok so I went back and looked at our frame and our frame without anything weighs 20.9lbs. It is made out of custom aluminum plate and standoffs. This is also without any lightening patterns so that the machine shop wouldn't hate us too much haha.

potatoarecool started this thread by asking how heavy a chassis made only from material from the Kit of Parts would be.
