Re: Can the toughbox and axles support the entire robot

AndyMark has a long output shaft available as an upgrade option to the KoP toughbox unit that extends the output shaft by 3" or so.

We use that and support the outboard end of the shaft. It works great.

I don't know how the toughbox would do on a direct drive with the cantilevered load... it's not just the weight of the robot that you have to worry about, but also the tension in the chain... which, depending on the diameter of your sprockets, can become fairly significant. Add that to a bit of shock loading from a bit of looseness in the chain and... well... the toughbox can probably handle it, if your wheel and sprocket are mounted fairly close in, but I've never wanted to be the one to test that theory.
