Hey again, so for my drive I been thinking how many motors and what the gear ratio. Been debating on chains and gears but never got successful with chains so it’s drawing me back. Thanks in advance.
4 motor 1 to 1 high speed
Personally, I chain 1:1 with 6 motor turbo or 4 motor high speed. I’m not really a fan of gearing my base because it just feels like a hassle to me and takes up space I’d use for other things.
So far I’ve seen most people using 1:1 HS with 4 motors
Can you use 4 motors and chain it or would it be to weak
Right now, my 4 motor drive is chained and it works very well.
@Harsha Jagarlamudi Any photos?
@Juster This an old robot we built earlier in the season but its a simple chained 1:1 high speed base. You can sort of see the sprockets but we just didn’t put the chain on yet.
Try to use 1:1 direct drive or gears to transfer power because chains causes a lot of loss of power during transfer from motor to whatever you are driving.
I have seen people use 4 motor high speed or 6 motor turbo. All are on a 1:1 ratio. My team prefers to have a 4 motor high speed and we will most likely use any additional motors for the lift
6 motor HS for that little bump every here and there.
How necessary is a HS motor for drive. We went to a competition today with 6 torque motor drive - and it worked perfectly fine - it was quite fast already and I’m worried HS would mean that it is harder to control. What do you guys think?
Naw. HS is the best for a drive. It is really fast for a mogo robot, but for any regular stacking one, the weight will keep it civilized.
6 torque… that probably is a little much. I think changing to 6 HS is definitely worth, with a little driver practice it makes a difference between scoring the last mogo in the last 10 seconds and still parking, and not being able to do one of those.
Yh - we had about 30 minutes of driver practice before our first match - we’ll change it soon - thanks for the advice @Easton , Atlantis
Although if your robot is 100% steel, do the 6 torque drive.
True, but for most robots, you won’t need that much torque
That kind of pushing power would be crazy for defense, however.
True. But what I’ve noticed so far is that pushbots with like a 10 motor turbo do better than ones with a 6 or 8 motor torque. Though the torque ones can push more, they can’t ram into the other robots and cause them to drop cones as well. The fast ones can also push 4 motor tank drives (with Omni wheels) a lot further away from their zone during the 5 second defense allotment before backing off.
The robot I’m building now is going to have 6 or 8 turbo motor (no,it’s not a push bot or mogo only bot).
