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.

Techfest is IIT Bombay’s annual science and technology festival to promote technology, scientific thinking, and innovation and has surpassed 22 golden years of creating an unmatched aura year after year. It is well established as Asia’s Largest Science and Technology Festival patronized by UNESCO, UNICEF , STARTUP INDIA, DIGITAL INDIA, SAYEN and CEE with a footfall more than 175,000 people comprising mainly of the youth from across the nation and an outreach of over 2500 colleges across India and over 500 colleges overseas . Techfest has proved to be a great success in attracting International countries like Australia, Singapore, Indonesia, Sweden, France, Brazil, Spain, Thailand, Sri Lanka, Nepal, Pakistan, Bangladesh as well as from Denmark, Egypt, Ethiopia, Russia, Syria, South Africa , and UAE in previous editions. We are organizing International Micromouse Competition which will be held during 3rd-5th January, 2020. The total prize money of International Round is INR 175,000 . Below are some of the resources of Techfest, IIT Bombay which shall give you a clear picture of the festival.

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 moves The 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. Diagonals For 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 .

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. UK Micromouse 2019 – final maze. 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 only 3.9 m/s. The first speed run took about 8.2 seconds – I don’t have the detailed timing data yet. The last ...
