When I took a featherweight to Robogames as checked luggage, there was no customs problem at all. If you freight it separately, there should be even less of a problem. I found that some of the cheapest rates are from freight companies specialising in excess baggage; just Google "excess baggage shipping" and you will find plenty of leads. From Australia, air freight was cheaper than sea freight and took 5 to 10 days.

I have never freighted a 100 kg heavyweight to San Francisco so I can't say.

I have gone with 2 bags, one containing a 60 pound lightweight robot and the other containing a total of 7 one pound and three pound robots, tools, spares and batteries and have had no problems with American customs. The bags always get opened for inspection (this is done out of my sight, I know because they put a card inside saying the bag has been opened for inspection) and I always include a large notice, right on the top, which says that the suitcase contains robots for competition at Robogames, the date and place of the event, and the fact that there are no wet cell or lithium batteries and that all batteries have been disconnected and terminals taped over. I don't say combat robots. I run my Robogames robots on NiMH batteries to avoid lithium batteries - the airlines all forbid them in luggage.

The notice works well, I do the same. Most airlines do allow Lipo packs, you just have to read the (very) fine print and each airline is a bit different. I flew four packs to the UK on Etihad this year and they didn't have a problem. Their rules state the maximum number of watt-hours for the packs and that they have to be in checked luggage. I took a print-out off their web site when I checked the bags in and they just put a fragile sticker on the case.

We sent 10 heavyweights and 6 feathers over to Singapore and back the other month without an issue. Its cheaper if you can carry anything they consider as dangerous goods (ie batteries of any kind) in your baggage and not ship it. You can take Lipos on a plane with you, there are just limits, but in most cases each person should be able to carry a heavyweights worth.

KLM/Air France have a 160Wh Lithium limit on checked baggage

Each category of robot at Robogames has a 30 machine limit. The 3 pound RC and 220 pound categories are now full. The remaining combat categories as of today are:

Category Current number of entries

150g 4
1 lb 18
1 lb autonomous 0
3 lb autonomous 4
60 lb 16
120 lb 15

[john_frizell]

As of today the 1 lb RC category is also full. There are 19 each entered in the 60 and 120 lb categories. Lots of space left in the autonomous categories although the Brazilians are signing up some very powerful machines. Am looking for ways to get more armor onto my 1 pounder.

A trip to Robogames is unlikely to disappoint.

Unmakerbot just signed up in the lightweight category - I'm screwed

[john_frizell]

You think? Just another drum spinner in a field that is over half spinners. Or do you know something about it that I don't?

To be fair it is a very very nice drum spinner. Packs hella punch too.

I found some videos on Youtube - it totally raped Touro light and I didn't see it lose a match or break down. It didn't win the event (didn't see why) but the amount of damage it did makes me nervous.

Here are some Unmakerbot matches:

VS Federal MT: https://www.youtube.com/watch?v=OhcQB4PwhDQ

VS Aquiles: https://www.youtube.com/watch?v=ZkGxZiIFXck

VS Blue: https://www.youtube.com/watch?v=Xn5TaOQ8u1Y

Its not clear what happened to Unmakerbot in that clip; it might have been hung up on the arena. One encouraging observation is that the bot can barely move when inverted.

Bottom line - I am REALLY glad my design has a rear wedge!

[Max]

From the videos I watched he doesn't seem to be very actively offensive, he tends to just stay still keeping the drum facing at the opponent so when they eventually try to attack him they get destroyed. Seems to suffer from major gyro issues as well, I think going be beaten if you had good, quick but controllable drive so you can out manoeuvre him and hold back a but more forcing him to make a move. Or else have a well armoured reliable bot that can afford to be more attacking as it knows it can take the hits and maybe win on aggressive style. But does look like a seriously scary machine!

[john_frizell]

As I may have mentioned above, wood is very good armor against spinners. They chew it up but in shredding it carries the energy away and greatly reduces the impact on your bot and stops you from being thrown. You may need to replace it after every fight but 2x4 is cheap. You might want to bolt a chunk on over your rear wedge.

The wedge is already 14mm thick titanium - no need for a 2 x 4!
