One thing we may need to look into is how we distinguish between our reflected signals from the barriers and the other robot. A sumo arena could have no sides but if we go for full combat we might need transparent or slopeing walls. Also we may well be detecting the signals from the other robot so that might actually make it easier. Maybe a ruling on stealth measures would be good but I wouldn't want to have to draft it.

I have the same worry about reflections from the enclosure walls. Perhaps we should start with sumo and no enclosure? Full combat could cause problems without resorting to a huge enclosure...

I think the minisumo rules prohibit deliberate jamming, but allow "passive" stealth methods. I think they also allow "confusion" tactics.

I now have an autonomous robot, will be programming it in the next few weeks. I will bring what i have to AWS19. It is basically a seven dwarf robot. It will also be tracked. I will be building it to the 4" cube but has any dicission been made about the weight. I plan to use a TX battery pack but this could easily be replaced with Lipos.

ATM the robot has 2 transmitting sonars and 1 reciever sonar, giving a left and right signal. I plan to add a sensor so that it can detect the edge in sumo, and currently have no intention of fighting in any sort of combat other than sumo.


Anyone else got any further?


EDIT

Pictures, as it is to the university specification, will modify the ali chassis with 4mm supports inside

Current weight 300g, the motors are 50g each, loads of places to save weight so if it needs to be 150g i can take alot out.

Cool!

I have built my PIC processor board and some IR sensors for edge and opponent detection.
I now need to program/debug the board and put everything together.

Drive is 2 standard servos, using the PIC to generate R/C-type control pulses.

I was aiming at the minisumo rules, 4" square footprint, and a whopping 500g weight limit. Most of the weight will have to be batteries and ballast, unless I use a lead chassis! :wink: I should be able to get the weight down to 250g with "normal" batteries, but I don't think I'll get to 150g.

Anyone else made any progress?

The problem i have found so far is that this is i have just built this robot, given a box of bits and said build this. Building can be fun but designing and driving are the best bits of ants, so am going to redesign this one for the 10cm footprint, 500g is easy. I will see about getting some copals for drive and replace the OTT ali chassis. Would quite like to design my own board sometime with more sensors. I belive that this could be used as a super ant at the next RRC, if i can an ant at the aws :)

Hib, Adam's planning to bring his auto to AWS19 too, (unless he's broke it or something recently). We could have an auto championship with the 2 competitors if you want.

progress report on my Autonomous thing: Got board sorted, have US tx working, and most of the reciever circuitry made (need a couple of chips before I can test it.) I should have the basic robot sensing done by AWS 19. Won't be armoured, and won't be able to detect lines, but it would be able to fight. hopefully, if I haven't stuffed anything major up.

Machining wheels on the lathe tomorrow, yay! :)

I have a single 3 hour session on thursday, i will put a basic drive away mode in as that is what the uni want for some strange reason, then will change the motors arround 8) .


Adam, do you want to have a little sumo fight? And Gary if yours is ready?

Sure, if my project runs... should be at the stage where I have to put a couple of chips in, and then program by the end of the day. God knows when I'll get those chips though :(

We've been programming robots at my school too, but with RCX 1 though (those big yellow lego things in Mindstorm boxes). Donno about the weight, but its really simple to program if you got Brixc commandcenter (I think).
