It is 24 hrs until our first sumo competition and I'm thinking about reversing nearly all of the changes I made to the sumovore my wife and I want to compete...
... Well not *all* the torque, it's also highly dependant on what type of PWM mode you use. ... The basic stamp will do PWM but it chews up lots of clock...
... Good luck?! ... You have my sympathy! Ori Barbut posted a dual power supply that cured many of my problems; you should be able to find it. It uses the kit...
... Well, I didn't get it all nailed, but I got it good enough that I didn't embarrass myself. I realized on Friday when I helped set up the venue that the...
Way to go! I'd say that was a pretty dang good record for a first competition! ... You beat him...and he's in first place? No shame there! At the NAIT...
... Heh, it's been a while for this email, but it's on my to-do list. Later, Dave ... "Um, no - that's H,R,Y,N,K,I,W. No, not K,I,U,U, K,I,_W_. Yes, that's...
I now see that this other mod was discussed last May and will eventually be part of the Sumovore Kit and be available to existing owners as an upgrade. So...
Hi: We finished assemblying our Sumvore and the left motor does not turn. I checked the continuity between the solder pads under the left motor terminal block...
Sounds like you've done a good bit of diagnosis so far. One common problem is a poor solder joint, or even one that got missed entirely. Take each board,...
... Hi Lawrence. I recently had a troublesome Sumovore with a similar problem as well, and I traced it back to a cold solder joint on the brainboard. What it ...
... And since I may be owner of the sumovore to which Dave refers, I'll mention the need to use a magnifying glass. I had already carefully examined and ...
I have been having trouble with my BS2 Sumovore (with high speed motors) over-running the shikiri and off the ring. Thinking the BS2 was simply too slow, I...
Hey Tom I'm not the best at programing the BS2 so don't laugh. Can you set the line detection to responce to speed up the wheel on the side that detects the...
Hi Tom, I noticed this with my Sumovore (even just using the built-in analog brain). The problem is that there is a gap behind the scoop, and when the scoop...
Hi I am very new to all this, and have built my robort and it works. I have also built another board to allow me to put a chip on. I have an OOPic chip, but...
Hi Barney, ... I don't have any code, but from the brief look I've had with the OOPic, you really need a book or manual. Dennis Clark has a book on the OOPic....
I'm not laughing, Gord. I've been trying to get this @#$!# to work for two years so I'm nothing if not persistent. Yes, I've tried that strategy and it worked...
MessageI had noticed this too, Dave, and soldered heavy brass rails to the scoop (it adds weight and helps keep the scoop down). I also extended the angle of...
Hi I was also woundering weather I have to use OOPic lanuage. I do have an OOPic chip, and this is why I seem to think I have to. What other software is there...
Hi Tom, OK - the next trick I would try is the one I used on Stinger (and Phantom) I went to Lee Valley and bought some friction pads. They have a couple of ...
Hey Tom what are you using for tires? Steve Jones retro fits the rubber band with sticky silicone tires that really grip the ring. Maybe the sumo is reacting...
Hi Gord, ... My opinion is that wheelie bars on the back are a bad thing. If any other bot gets their scoop under yours, then the wheelie bars become a pivot...
Hey Dave I See your point. Seeing how well your bots do I take your work as gospel. :) Gord ... Stay tuned for 2005 ECRG updates. www.robotgames.ca ...
Whilst I agree that the larger wheel sized sumobots seem to be more tippy than some, part of that problem is in their design in that many have the bulk of the ...
MessageSneaky! I only have those two rails, but could easily solder a flat angle on to them. Worth a try. Thanks again. Tom ... From: Dave Hylands To:...
The rubber band tires, for now. Things happen fast, but I can see that the motors are not reversing until after the point of no return. That's why I ...
Good suggestions, which I have already incorporated. My SV has a galvanized metal chassis, battery pack screwed to it, wood block screwed in center between...
I've spent the past hour or so with the scoop of my sumovore propped up on a tiny wedge of foam, passing bits of white paper under the sensors and watching...
Hi Tom, Hmmm. It sounds like you're trying to use the sensor in an analog fashion. I wouldn't bother doing that for the line sensors. This will probably...
