Hi all Good to see Duncan kicking up some dust again! As Pete suggests, we are planning an event in late November. This will be an informal competition ... held in the TIC itself, not in thinktank theatre. I am currently sorting a date, and we are hoping to have one or two other events such as drag races and time trials, as well as the wall follower and maze solving competitions. We may have a seminar running at the same time, targeted at the much more general theme of pervasive/ubiquitous computing - that depends on whether the building work currently underway is completed on time, as one of our labs has been pulled apart over the summer. Whatever, we will hold the mouse competition - but we need a name for it! We have Micromouse, Minos, and ????? As it is the last time the mice will be seen until Easter, perhaps it should be a (hiber)national event? Some ground rules need to be set - some VERY SIMPLE ground rules - so that you good people out there can start preparing. We will be having our August meeting of the Midlands Micromouse club on Wednesday August 3rd, so suggestions please. I will ensure that we have a firm date before the end of that week. I have used the rectangle thing as a test track for student wall-followers. I think a known track such as this give us a benchmark figure for mice. I also thought of having the maze re-arranged to form 4 lanes by 32 cells for drag racing - no parachutes allowed.

These times are, of course heavily dependant upon the actual maze. I have found data for a couple of mice on the net (you may need to mess with your font settings to see this neatly) : Name Ning 2 Min2 Min3 MM3 owner Ng Beng Kiat Ng Beng Kiat Ng Beng Kiat Itani length mm 122 117 113 130 width mm 80 75 74 60 height mm 70 50 41 52 mass g 713 332 290 350 speed m/s 2.5 2 2.1 2.6 accn m/s/s 2.5 2.5 2.8 3.2 For what it is worth, Maximus (you remember - knocks down walls and crashed a lot) was set for an acceleration 2.8 m/s/s and a top speed of 2 m/s. It is clear from the table above that a mouse that can handle consistently at 3 and 3 would be in with a good chance against most competition. All the above mice can accelerate much harder and travel much faster. I believe these are the actual running settings used. If anyone else would like to share their performance data, I am sure we would all be interested. It is good to know what you have to achieve to be in with a chance. Now, controlling all that power.... The only common test I have come across on the Japanese sites is a full circuit around the outside of the maze. The simplest way to set this up would be to time the mouse between subsequent passes through the start gate, having removed the east wall from the start cell. Mice would then just need to be told to do a simple set of moves. I have asked Tony if we can have such an event at the proposed semi-formal autumn/winter event at TIC. We are looking at the end of November I think. More details from Tony if we can go ahead with this. I have a video somewhere of a stepper driven mouse doing this in under 10 seconds and I think 6 seconds would be a fair goal for a mouse accelerating at 3m/s/s. As for how useful it is, well the ability to steer at speed is fairly critical and it is a simple, easy to set up task. Any well-defined, repeatable task would be interesting as a year-on-year comparison of performance. I have been unable to find published data for this although I am sure it exists somewhere. It may also be a good crowd-pleaser at a competition. Pete Harrison
