Team Pushover: Build Log

[Retroman]

In all honesty that's how I got the one I have, it said in stock so I just bought one ha. Cheers for keeping an eye out too!

But yeah, that faceache thing is toxic...

[Retroman]

IT LIVES!!!!!! sort of...

Reversed the polarity and pit it back how it should be, and everything kind of works, the Vex29 is snappy and responsive, the grabber moves faster than I thought it ever would and it grabs with 750g or pressure at the tip, I'm delighted!

But now for the kind of, the NanoTwo didn't seem to survive so well, it's obviously receiving and processing the signals, but the motors will barely spin even with full stick movement, and I *think* it was beginning to get warm... damn...

[Bad Wolf]

Glad its kinda of working mate! Fingers crossed its saveable!

Im re-thinking my orignal idea of making an Ant weight version of Bronco, but this time Im going to have it printed out instead of making it the size and weight of a ugly tank haha

[Retroman]

Mmm... I think the NanoTwo is toast if I'm honest, I might try and get hold of Rory through the week for a professional opinion.

Just been checking out the CAD in your post, looks good, what internals you going to be using? Sticking with 4wd?

[Retroman]

So, no update for absolute age, sorry. Team Pushover has been at a standstill over the summer, this being a responsible adult keeps getting in the way.

Pullover is now on version 4, and I was hoping that at Botfest I could throw it in the arena with everything 100% working (previous 2 versions have all had some pretty serious weapon issues)… but even now it. wont. work. Having replaced the cooked NanoTwo with the latest version and a new receiver, my Devo 7e has decided to spit it's dummy out instead... great...

Wej the experimental front hinge monstrosity is hiding on a shelf as my building abilities and available materials can't get it below 212g whilst being stable enough to stay in one piece, so it's replacement entry for Botfest will be DerpWej, a hideously ugly and poorly build lump with a monster lifter.

As the 2 previous events the "Flagship" of the fleet is the better made of the 2, but suffering from electrical gremlins again. and the thrown together heap works beautifully. I'm spotting a pattern.

Pushover; The team mascot is now more than a box of parts, a 6mm aluminium base with aluminium angle armour supports sits proudly on the work bench, the flipper arm (paddle?) is also present, HDPE sides are cut but undrilled as yet, and the left hand drive motor has seized it's gearbox. So we have an immobile space frame of 6mm alu and 18mm HDPE that looks halfway decent, remember that pattern I was talking about? yeah...

Pics of Pushover soon once the sides are drilled on mounted.

[Scarrosaki]

If no luck on the Devo7e, I'll be bringing a second one with me. If you want to use that one, be my guest

[Retroman]

Awesome stuff Scarrosaki, really appreciate the offer, obviously i’d Like to get my own working because Pullover is as yet untested, I don’t even know if it works

Feels good to have a backup though, cheers my guy!

No worries dude, give me a shout at the event if you need it and we'll see if can get it running. If you've got a bind plug though bring it, as there's a good 70% chance I'll have lost all of mine

[Retroman]

Funny enough, the bind plug is currently plugged in...

If I have to wait until event day, I’ll have to manage, it *looks* like it will work, and it’s within size (same body shell as last time) and only about 130g minus 2 screws... so it passes every check except the figure-8 right now

[Retroman]

So after narrowly averting disaster with the Devo 7e (I wiggled the power switch ) we now have 2 fully functional ants again!

Pullover weighs in at a hefty 129g ready to fight, I'm thinking of adding a scalpel blade to the grabber for grip and some putty for ballast under the nose, but that's all we'll need I think. It currently can wheelie on command and rocks back right up onto the rear wedge section, without the undertray it actually flips itself up onto its rear .

specs: 2s 330mah LiPo, NanoTwo, Lemon RX, Vex29 weapon controller, 700g+ (part charged atm) force at grabbing tip, still too fast for my terrible driving.

DerpWej is slightly porkier at 143g and now its stopped tearing its lifter motor off is also 100% fighting fit... if ugly as sin...

Specs: 2s 330mah LiPo, eBay antweight dual ESC, flysky rx, can lift 750g

Both fit (just) in my 97mm build cube, so breathing room for tech check.

Not as neat as last time, but also not wired up backwards , 1st pic is Pullover on left, DerpWej on right. Pic 2 is the underside of Pullover showing the ridiculous 65x55x25mm space I wanted to cram everything into, because I'm silly.

[Scarrosaki]

Awesome, looking forwards to fighting them!

How's Pullovers weapon working now, iirc last time you were having problems with some horrific lag on it?

[Retroman]

Ah yes, that lag was... interesting...

i timed it when I got home, from pressing and releasing the stick it was 0.6 secs to move and almost 1.4 to change direction, but now it snappy and responsive, so much so that I want to add a dead band to make it less twitchy, good power now too.

I seriously question whether DerpWej is even remotely competitive, I think our front angle is a little steep, but it pushes like a tank.

anyway, bring it on! I’ve lost to you before, I’m sure I can lose to you again

[Retroman]

Botfest 3 today, and mixed results for Team Pushover...

Pullover performed very well, let down only by the nut that was holding the controls . On out 3rd attempt, we finally scored (lucky) win against Bodacious Fyraan-Gaaris, and went on a good run managing to beat a few others, although lost to both Voodette, and Janet Street Porter. Ended up out in the heats but finally seem to have the robot working as it should, except when it died randomly - never just works well does it? So I have a loose connection and a dodgy power switch on the Devo.

As for Wej… well... it's going in the bin. It. Was. Terrible. I managed to be embarrassingly and overwhelmingly beaten by almost everything, I did score 3 points after Psycopathy (I think) gave up. Turns out we have some serious design flaws, with the arm down it was too narrow to push, the arm itself had to be shortened for the box and ended up too steep, and with the arm up it wheelie'd everywhere and left enough room under the front for a small car to park up. Pants.

Also shout out to Kev with Spinnahhh, I fitted a bulldozer scoop to Wej for the rumble, which he proptly chewed off, followed closely by the wires to the weapon motor!

There are plans afoot however, find the loose connection on Pullover, fix the Devo, replace Wej (Spinner perhaps?) and crack on with Pushover and see if we can't have something to display next time.

Enjoyed my little self though!

Did you use CAD (compression aided design) there?

[Retroman]

Did you use CAD (compression aided design) there?

I wish there was some aid... it’s turned into a freak show where I need 3 thumbs, 6 fingers, the planets to align and to hold your tongue *just right*, ideally needs a rewire to fit the new shape, but I’m lazy...

On a side note, I think I’ve found the loose connection, it seems to be the plug onto the rx carrying the bec, this particular receiver is destined for PushOver, and is a bit too big, so once my pinless rx arrives I’ll do said rewire and need less interference from the gods to get the bottom on

Also, has anyone repurposed an electric axe mech to use as a flipper? It will give me a better layout for the PushOver regarding removable body panels for access (if my pencil tells the truth anyway). Thanks.
