Dreamcrusher has been put back together after finding a faulty wire Smile

We have set up a Facebook page (shameless promotion): https://www.facebook.com/oyesrobotics/?fref=nf

Also we have done a Vex/FRC style reveal, so we will have something to remember the bots by when they are inevitably smashed to pieces next weekend: https://www.youtube.com/watch?v=KK9pEeoG6m8

Wow, what a weekend!

First off we would like to thank Big Boys Toys for their support and Steve/Erika and the team for setting up such an amazing event - all your hours of hard work certainly paid off. It was awesome to meet you all, the atmosphere is great and you are all really helpful whenever we needed anything Smile

We were surprised with how well we did, the robots only took minor damage overall and outperformed my expectations of them greatly. Dreamcrusher dropped a chain a couple of times - we fixed this for day 2 by adding a chain guard to stop it popping off. The Undertaker was having ongoing electrical issues on day 1, which we found later (Sunday morning) was due to some melted wiring packed away inside - cheap speaker wire really shouldn’t have been powering the whole bot! After spending most of Sunday rewiring, it seemed to be back to its normal pace.



New builder things we learnt the hard way:

Have the right gauge wire, just because it works in testing doesn’t mean it will hold up in battle.

Make sure that your speed controllers have room to cool off, we zip tied them to the motors (with foam blocking the cooling holes!) and they didn’t turn out happy. Everything gets MUCH hotter in battle.

Check over the robot straight after a fight, don’t “leave it for a bit” before tightening the screws. You never know how long its going to take. We had to do some last minute repairs because we let ourselves have a rest after a fight.

Wedges should touch the floor, Dreamcrusher's wedges would have almost been as effective if they were just flat sides - gotta get under the opponent to do any damage.


Steve (our Steve) uploaded some of our fights on his YouTube channel, I'll bug him to upload the rest at some point: https://www.youtube.com/user/stevenbarksalot/videos

We will hopefully be back next year Laughing

Congrats guys, you absolutely smashed it! I would drop the chain and go with a belt like Nick uses (TPU style) as you want a bit of slip in the system to help protect the weapon motor. I noticed the scorpion was gone on the 2nd day, hope it didn't break! To be honest though, those cheap outrunners are amazing for the price as long as you re-epoxy the magnets to keep them in place.

Hope to see you again next year to defend the title. Also let me know if you need help with the printer. Wink

The scorpion is still good, the shaft just slipped a couple of mm out of the motor so it was out of line with the chain, was easy to loosen the grub screws and push it back.

We will definitely be looking at a belt, we just ran out of time this year to get it sorted Sad

The printer is up and running and producing beautiful prints, a real step up from what my old printer can produce! Thanks Very Happy
