BOB FW Series

[Ocracoke]

I guess that is the question, what does the wiring look like? Do you have a diagram you can post?

[Maxamuslead]

If Sean stayed with the 30a ESC then it would of be a factor. To be honest there are so many possibilities it possible they all contributed

[Ocracoke]

It would be a factor yes but the Barróg team had fairly similar ESCs to BOB I think - certainly as big as BOB as well and 4WD. Might be worth checking with them?

I let this thread get dusty, I must fix that.
A long overdue reason why BOB had trouble driving was due to one error, me. You know those small balls in the gearbox, well that gearbox came lose so I screwed it back up, only to do it the wrong way and the balls fell out. At the time found most of the balls and put them in a box to put them back in later, of course later on I forget to do that and I'm sure you all know how well that went back in Manchester.

Moving on now with the next robot BOB 2, this time it's going to be a thwackbot.
Redone the wiring a bit, made a new body for it.

Just need a bit more work to it and it should be done ready for Robodojo.

Most people would use grub screws in place of those pesky balls to lock the clutch, I ran my first event with the balls, and in the end the came loose. so Cheltenham i ended up grubbing them, and they lasted for all battles, no issues.

'Sigh' There's always something going wrong. A few days ago I tested the components to see if they still work, they did. But today when I put most of them in just to make sure it fits, it just jitters, the light on the feather two goes on and off when I move the joy stick, the same thing happens on the ranglebox, only they don't have the LED light.

Since it does on both of my ESC the problem might lie with the wires or the motors.

Yeah same, I grub screw my featherweight gearboxes. The way they come is alright, but completely inadequate for combat I've found

Is your battery charged? Sounds like voltage sag/low voltage.

[sean retro]

Problem solved, just make sure that the safety link has been pushed all the way in.

[Ocracoke]

I have this problem with the XT90-S link on my Middleweight. If I don't push it all the way in, it lights up but then fails to move at all. A good reminder to check it when diagnosing a problem :P

Well after taking it to Robodojo, it worked better than BOB 1 back in Manchester but it seemed to didn't want to drive straight in all of its 3 battles. Won't be able to check what went wrong because in its 3rd fight the receiver died on me so I'll have to get a new one.

Out of its 3 fights.
W 1 - 2 L
Go to 3:23

Update.
Ok so it turns out the receiver didn't die on me, it was the fuse. Good thing I didn't throw the old receiver away, just need to remember where I put the spare fuses now.

Well after taking BOB 3 to Robodojo, I can happily say for the first time I didn't have any drive problems like the other two.

When I got there BOB 3 was still not finished, still needed to make a hole for the safety link, a holder for the battery and the ESC, also some wires needed some soldering before its first fight. I only just finished the important things before it first fight, of course without its weapon.

First fight.

Went well nearly got Midas out a few times but he got me on the pit where my wheels wasn't on the ground. Other than that it was a good fight.

Secord fight.

Didn't need to do a thing.

Third fight.

Mad Henry is a quick little vacuum cleaner, driving around the place until he pulled a Onslaught and drove on BOB 3 and landing on his side.

Fourth fight.

While Mattock kept hitting me with his axe, I kept ramming him until BOB 3 stop driving.

Well I made the same mistake again with the receiver when really it was this.

Just need to make a few things to it and it'll be ready for next time.

Late Robodojo update.

After the first two fights I started to have some drive problem, from what has happened the grub screws for hub stay on the gearbox came lose so the wheel will just spin around, also the screw that keeps the hub from sliding off is doing the same. Those two problems have cost me the last two fights.


I was told there was some sort of glue that helps with this of course by the time I got home I forgot what it was called. Does anyone know what it was called?

[Coolspeedbot]

Sounds like thread-lock like Loctite blue (243)

[sean retro]

Yeah, that rings a bell, I might have to get one to keep those screws in place, when it comes lose its doing this to the shaft.
