While working on a Python application to do real time plotting of data, I needed a way to update the data. The data arrives over the serial line and can be received at quite a high rate. easily a few thousand elements per second. The basic idea was to have the data stored in a list. When a new item arrives, the list must be shifted down one place and the new item placed at the end. Clearly, this should happen as quickly as possible.

When a micromouse robot is trying to determine the best path from start to goal, it is helpful to be able to calculate the amount of time it will take to run along the straight path that connects two turns. This is not an obviously simple calculation because there is the question of how fast the robot is travelling at the start and end of the straight, the available acceleration and the maximum speed limit.
Some simplifying assumptions will help a lot. First, assume that the start and end speed for the straight is the same That is, all turns are made at the same speed. Second, assume that the robot is always either accelerating or decelerating. That is, there is no top speed limit. For many actual straight section in the maze, that is likely to be the case. Finally, assume that the acceleration and deceleration is the same so that the straight run is symmetrical.
Orthogonal movesThe classical equations of motion give an expression for the time taken to move by a distance, , if the acceleration, , and start speed, , are known (suvat-rearranged)
(1)
Considering orthogonal moves first, the distance, , can be expressed as some multiple, , of the length of one cell, .
(2)
Substitute into (1) to get:
(3)
It is now convenient to specify the start speed, , as some constant, , times the distance through one cell.
and the acceleration, , as
For example, for , a classic micromouse might be able to turn at 1800mm/s and accelerate at 18,000 mm/s/s.
Substituting into (2):
(4)
)
(6)
Equation 6 describes the time taken to accelerate to some top speed over cells. The micromouse robot will accelerate for half that number of cells and then brake for the remaining half. Split the motion into two parts:
(7)
This result is easily pre-calculated in a table of for suitable values of and so it will be easy to determine the time needed to run any straight or arbitrary length with a simple multiply. Note that this only works because of the common factor, , in the speed and acceleration.
DiagonalsFor diagonal movements, each cell traversed is mm long and so the time is calculated from:
(8)
Note that you cannot simply multiply the result from equation (7) by .
TwitterFacebookLinkedInRedditEmailPinterestWhatsAppThe UK Micromouse contest took place on Jun 1st at the Techfest 2019 event. I am happy to report that, from a personal perspective, it was almost entirely without drama.
[update: full results are here: https://ukmars.org/index.php/TechFest_2019 ]
There was a worrisome moment when the program would not build on the new laptop but that was just unfamiliarity with the process having done it differently for a good few years.
The maze had quite a long path I took the magenta route which was a little over 14m long.
And my final time was 6.37 seconds an average of about 2.2m/s. It felt like it should have been quicker but there were no long straights. The top speed reached was only3.9 m/s.
The first speed run took about 8.2 seconds I dont have the detailed timing data yet. The last run was performed at the maximum available speed setting and there were no visible errors. The penultimate run clipped a post. I heard it but saw no sign of disturbance.
There were 33 turns and 17 straights in the path. The search took a while and the battery voltage was down to 7.5 Volts at the start of the first fast run and just 7.14 Volts at the start of the last fast run. That will have limited the top speed a little.
We did not have a huge entry list this year but here are the fastest times:
OnSaturday 1st June the 2019 National Schools and Colleges MicromouseCompetition was held by the UKMARS organisation and hosted by Birmingham CityUniversity as part of the annual City Centre Campus TechFest event.
Asusual three events were run: The Drag Race – a 6 metre sprint following a whiteline; the Line Follower – a circuit of straights and curves of varying radii,again following a white line and the Wall Follower – finding a route from thestart cell to a target cell in a maze by following the left-hand wall.
Atotal of 20 mice were entered. Many ofthem were capable of, with a change of sensors and wheels, competing in allthree events. There were kit mice and scratch built mice on show. The lightest weighed 97 grams and theheaviest 330 grams.
Newto the competition this year were Kesgrave High School, Ipswich who had beenworking on their designs since October 2018.They are an after-school club formed by retired teachers Simon Clapsonand John Fisher, both stalwarts of Micromouse who previously enjoyed greatsuccess in this competition with their former school. Schools are desperately keen to get STEMambassadors to run robotics clubs but are generally very inflexible regardingusing school computers to run suitable programming software. John and Simonwere very limited in the choice of microprocessor for their students’ robots andhad to abandon their tried and tested Picaxe programs, eventually settling forCrumble, an icon based software system similar to Scratch.
Severalclubs and schools from Buckinghamshire were again represented and there was oneentry from a primary school pupil, Maxwell Bayliss from Pershore Junior. Unusually there were four entrants who wereveterans of the 2018 competition making a return appearance: KaviyashreeDamodaran, Nathesa Sivakumaran, Lahari Ballina and Bethan Edwards.
BethanEdwards was the stand-out performer on the day.Her mouse “Jerry” came first in the Line Follower (beating her brotherOwain into second place by 0.05 seconds), second in the Wall Follower and thirdin the Drag Race.
Medalswere on offer for any competitor who completed a successful timed run in eachof the three events. There were alsotrophies for 1st, 2nd and 3rd placed mice in eachevent. Grateful thanks are due to DuncanLouttit of Swallow Systems who donated all the Schools awards and was ChiefJudge on the day. Thanks are also due toChris Evans and the BCU team and Ian Butterworth, Chairman of UKMARS forproviding us with excellent facilities.Last, but by no means least, we would like to thank the parents andteachers who supported the competitors and saw their charges fully focused andhighly competitive perhaps for the first time.
LightestMouse: 97.12g “Jerry”, Bethan Edwards,Wycombe Warriors.
BestRecorded Mouse: “Thanos”, Lekha Ballina, Wycombe High School.

Kylewrote the program for his mouse in just three after school sessions. His entry completed the wall follower eventsuccessfully – an outstanding achievement.

TwitterFacebookLinkedInRedditEmailPinterestWhatsAppTechfest 2019, held on Saturday June 1st at Millennium Point, Birmingham is the UKMARS main event of the year and includes the UK micromouse contest as well as a host of other contests.
Registrations now open at: http://registration.ukmars.org
At the 2019 Minos conference in April, the UK Micromouse and Robotics Society (UKMARS) agreed revisions to the rules governing its contests. Many of these changes were minor, to reflect the common practice that has been observed for several years. Some were more significant and are intended to bring the event up to date.
The most significant changes are for the UK Micromouse contest. This affects both the full size (classic) contest and the half-size contest. For these, UKMARS have decided to adopt a translation of the current Japanese rules for these events. There are minor changes to some details but, for practical purposes, the scoring for both contests is the same. There will no longer be a search penalty and the scoring is based only on the fastest run of each robot.
You can see all the current rule sets here:
