1712 Chassis Tests
 

Hey everyone-

Here are some links to tests we've done on the Regolith with our 70 pound chassis so far. Turns out that putting all the extra weight (approx. 50 lbs) in back makes turning great but you kinda can't drive at all, and putting all the weight in the front makes drive great but you kinda can't turn at all.

video of all weight in back:

Putting about 1/4 of the extra weight in the back and 3/4 in the front gives a nice balance...

We are also planning on experimenting with moving the front wheels as far back as we can to see how that impacts turning.

Enjoy! :)

Thanks for sharing. Just wondering - is your trailer hitch pivoting properly? It seems like it's restricted relative to other videos I've seen.

Yeah we realized that after our tests today, we think there is some kind of issue with the hitch, we're reviewing it now. thanks :D

Nice Vid and thanks for posting. Just wanted to ask, it looked like your wheels were slipping in the second video. How are you guys dealing with it, might want to look into traction control? Need help on it, pm me.

cool video but it seems like your trailer is being restricted from moving?? :confused:

Yes we know, see a few posts up

Thanks for the offer. There are our initial tests. What the video doesn't show is that, with practice, our driver was able to do pretty well and we're nowhere near done positioning wheels and distributing weight. If we get to a point in the next week where we're unhappy with our optimization through testing, then we'll consider adding the layer of complexity and we'll be in touch. :)
