Start a build thread to document the build and get feedback, practise driving.

^ Word..

THE #1 tip for winning. - *Finish your robot ASAP, and practice, practice, practice.

Dont aim to have it finished a week, or even a month before the competition. Aim to have it finished *as soon as you possibly can* (without compromising the build quality), and then work the hell out of it.

If you havent put at least 5 or 10 *full battery charges through it before you hit the area, then you are very likely to suffer an unexpected failure. If you do well, you will probably have to fight at least 5 or more matches at the event, and how can you know if you can do that if you've only run the bot for a few easy driving minutes beforehand ?

Expect to have to replace a worn out or failed motor or two, perhaps a battery. Maybe an ESC will smoke because your drivetrain jammed. Much better to discover the weak spots *now than in the arena.

Something *will go wrong (if you are practicing properly), and you need time to redsign and repair it, and then practice some *more to make sure your repairs are *stronger than the failed part.

Also, if something fails when practicing, you have plenty of time to strip down the bot (gaining valuable experience at taking it apart, repairing and reassembling it), which you will likely have to do *quickly at the event.. *and you will only have to replace the failed part...

If something fails in the arena, you will possibly have a *lot more repairs to do because of the damage your opponent may inflict on your ineffective machine. so in the long run, you are saving yourself work by eliminating weak spots first, even if it seems like more work than just building it once and then trying to compete.

Driving Skill is the secret sauce. A killer weapon is of no use to you if the opponent can dance around you and easily avoid it, and you need to be able to avoid whatever weapon the opponent has.

From dodging wedge-charges, to getting hits on the *back of a drum or vertical disc spinner, or spoofing a bar spinner into driving into the wall (hurting them without your getting hurt).

I used to practice driving my bot in precise figure-8s getting faster and faster each circuit and trying to maintain exactly the same track on the ground, first clockwise, then anticlockwise, back and forwards..

That way you get used to the constant stick reversals (right = left when coming towards you) as the robots orientation changes, and how its cornering changes as you speed up. (Guess who would usually win the Wacky Races ?) Smile

Then get a basketball, put it in an enclosed area with a kerb or net, cricket practice nets, empty swimming pool, whatever, and chase the basketball. gives you practice at keeping on something that is wildly zooming around the place and hones your chasing skill.

At the time, there were probably only 2 other drivers (You guys can guess who they were Smile ), that were at the same driving skill level, and I always could tell when I was in the arena with them.. (Obviously, but you know what I mean), sheerly from the intensity of the feeling that they were *on you.

As a benefit, the event organiser will love you, because you will be far more likely to actually show up at the event with a sorted well working bot that will make a good showing, rather than partly assembled bot with a "just a couple of little things left to do" that will really take hours, and no idea how well your batteries are going to hang in there, how long they will take to recharge and all the other things that come from *real driving practice.

Prior Preparation Prevents Piss Poor Performance.

That is the first thing you need to remember.

Sup newbie,

I say build a sportsman for nationals in October, hang off on normal feathers for now until you see what you may have to go up against so you can get a better understanding on how strong/methods and ways to do it

Sportsman class would be alot of fun for you though, no restrictions on how weird of a design and less chance of suffering heavy damage.

Is this your bots design? (image taken from dusKy's event registration)



I will leave it to more experienced builders to give you design feedback, I think you should start a build thread with your most up-to-date pictures, where the community can discuss your robot in more detail. There is a lot of knowledge here that will make you a much happier person come Nationals. Best to start a Builder's Report. Don't be disheartened, it is actually much cooler once you realise how destructive a featherweight bot can be. Smile

Which also illustrates my comment about driving skills.

If the wedge hadnt sat there and twitched back and forward helplessly, he might have been able to get behind him and wedge him into the wall.

Heres an example of *good driving. (And no, not just me. )

Andrew driving Sproing is very precise as well, which you need to be for a clamp/lifter bot. Notice Sproing deliberately driving backwards accurately to try and wedge IG. IG charges around at high speed, even inverted and watch the controlled turns and dodging of the lifter (he still got me a few times. A good bot was Sproing) Smile

Wow, was that really 9 years ago.. Whoa. no wonder the vid is such low quality

Just a note, it might not be a great idea to put the metal castor wheel bases across the tops of your battery cells. Smile
