Re: Bitza Mk2

Cheers. Seem to have gotten the gearbox working. Weighed the robot though, pretty fat, needs a diet.....

Re: Bitza Mk2

Know the feeling . Hannibalito was a tad heavy, so we started a rebuild with an ali frame.

Re: Bitza Mk2

Bit late for a rebuild now.........

Re: Bitza Mk2

Glad you've got the gearbox working. Any visible reason for the problem?
You had drill motor problems in the run up to the champs last year and finished joint 10th, so maybe it's another good omen :wink:

Re: Bitza Mk2

Haha, If it plays up again then I'm just going to off balance the drum and make a giant bristle bot, job done.

Re: Bitza Mk2

Just weighed Bitza Mk 2....

16kgs!!

:shock:

Re: Bitza Mk2

Ouch! Hope the drum doesn't conveniently weigh 2.4kg

Re: Bitza Mk2

Haha, no quite a bit more.....

Something else weighed 2.4kgs which we are sacrificing. I think it's crazy but Dan seems sure it's a good idea. All will be revealed on Saturday!

ditching the steel skeleton?

Re: Bitza Mk2

ditching the steel skeleton?

May as well. We all know duct tape is inherently stronger and lighter
Although my money is on the armour getting ditched. Works for the Beauty robots.

Re: Bitza Mk2

Trying to wire up this Relay, could do with a little advice:

http://www.electronicnetwork.ca/media/d ... u/sarl.pdf

It's unclear which side is the load side, I'm assuming 30 and 87 (for the motor) and 86 and 85 for the switch.
I'm also assuming it's polarity sensitive but which poles are which is also unclear.....

Thanks!

Re: Bitza Mk2

If its the same as my relay then you are right 85 and 86 are for the switch and 30 and 87 are for the motor. Mine isn't polarity sensitive but we may have just been lucky. Doesnt yours have a wiring diagram on the side?

[PJ-27]

Re: Bitza Mk2

Yes, but that's not massively clear either. I'll just press batteries to it until I hear it switching.

Re: Bitza Mk2

Word of warning it takes 12v to switch that relay (or mine at least) unlike the 100A one you had on Saturday which you may have been running off your bec

Re: Bitza Mk2

Thanks for the heads up.

Yeh the relay in Bitza can switch on as little as 3v, but the one in BitzaWood (Same as yours) requires 12v!

Also my switches require a common ground, so what ever I'm running the bot on will be the switching voltage. Means I can leave the BEC to just worry about the radio side.
