Skirt Update



I mounted my skirt to see if the screws in the center ankle would show and only the bottom 2 can be seen if you look from the bottom.
I haven't seen the painted skirt mounted until now and it looks funny to me.
I guess I'm use to the flat bottom.

I still have alot of work to get done before MegaCon and I hope I get it finished.
The skirts on the feet, Finishing the battery boxes, Painting the rear door
and alot of small details here and there must be completed.

We ordered the Sabertooth motor controller for the foot motors and I have the Cheap PS2 controller, So it will be wiring time soon.
For MegaCon, I'm going to wire the basics. Feet, Dome and lighting.

Looking so great! I am sure you will have him done and working in no time!!!

Looks good Calvin!! From this angle, it looks like you got the motor mounts level.

Is that a VEX controller I see in the back?

nice going Calvin... you'll love the Sabertooth when its installed. I couldnt have managed mine without it and the wiring is pretty much straight forward :)

WOW!!!!
Thanks Guys, :o)
Jason,
I'm working on your problem with the motors. We'll figure it out and solve it.

Jon,
Yeah I got luck and the mounts turned out nice.
That's 1 of my Vex remotes.
I plan to use them in my other droids and Scrubber droid.

Thomas,
Have you had any problems at all with your Sabertooth and the Vex?
Jason has a Scorpion and Vex setup and we are having a hard time trying to figure out why his foot motors are sluggish.

Well..I discovered a few things about the sabertooth..first you'll have to have a battery to power the wheels at at least 18amps...I'm using a single 12v 25 amp battery. It lasts 2 entire days with moderate running. I have tried to have the 24v 4.5 amp setup but have realized that its not the volts but the amps thats the important part. Another important thing is the signal from the radio control. Any signal interference can also disrupt the power to the wheels. I'm not sure if its the vex radio or RC's in general but there are signal disruption everywhere and because the sabertooth distributes the power this could be an answer as well...

...not sure if any of this helps but its what i have discovered this past month. When the signal was best I could run my artoo from a 150 yard distance without any problems making people think it was running on its own ;)

Thanks Thomas,
This may help explain why Jason is having so many problems.
He's having a signal problem and it seems the Vex is being affected by the Scorpions signal.
He's ordered another controller to replace the Vex and this should solve the interference.

On your batts,
The Sabertooth should have worked fine with the smaller batts at 24v.
What did it do when you were running them?

When I used the 24v battery with a 4.5 amp effect. It would work for about 2 minutes then it was too low so it would stall the motors. The LED reading on the sabertooth would read "low power" even though it was at 23v.

when i changed to the 12v 25 amp battery it never became an issue again. The reason why i don't install 2 of these batteries is because they are twice the size and twice the weight.

Another thing you could check is that if you reverse the "+" and "-" cables that go from your wheels to your saber, then reverse your control settings on your vex radio control. I did this and found that artoo worked so much smoother. Because my motors are mounted in the feet backward making the motors "pull" rather than push".... keep in mind to never reverse the power cables that go to the saber.

I bet this is Jason's biggest problem.
I'm pretty sure he's running small batteries and he say's his motors are very sluggish.
I'll email him to read this :o)
Thanks Thomas

Hey thanks for the ideas guys!

I did get larger batteries than the scooter ones...so now I have 2 12v 7ah batteries. Hmm..I did try a single 12v battery (meant for lawn and garden tractors or mowers) but it wouldnt budge the R2....not sure what is amperage was tho..

Thomas..how big is your battery?

I'd hate to invest in getting another battery and being stuck with it..thats what happened last time. They wont take them back at the store.

The life of thomas said...

its all in the amps Jason..my batteries that came with the scooters i use for my sound system and for turning the dome. My 25 amp battery is approx 8 inches square

Thomas

R2D2 Fett said...

Hmmm...well I am really tempted...wish there was a way to try first. Where did you get the battery? Automotive store?

Jason

The life of thomas said...

Yeah, I got lucky thee too. The automotive story was selling out their hi amp 12v batteries. Not sure if this is the type of battery one uses for motorcycles or outboards.
