Peter Harrison with Decimus5a the full run. Fastest UK Micromouse in 2022

The fastest run this year came at the end of a troubled session for Decimus, after several unsuccessful runs and on the final run it put in a time of 3.139, other faster runs were successfully completed but did not count as you only get 5 attempts.

Very good! A lot of work on that robot. Congrats!

[@jakatorussom5532]

Very nice

[@sUASNews]

An explainer for dummies (me) as a commentary would be good. For instance is that a tape measure on the chaps belt? What is the magic wand being waved that sits on the table???

[@MicroMouse]

Yes it is, never be without your trusty Stanley tape measure. The magic wand is some packing tape or that one may be a lint roller, it's used to clean the tyres between runs as the speed is ultimately limited by the grip from the tyres, you very often see competitors cleaning the maze while it's being assembled.

[@MicroMouse]

Adding commentary is something we should do and may do in the future this is not an amazingly popular channel outside the Micromouse world, its difficult to find time to edit the videos as well as we would like. Thanks for the engorgement. Nice channel you have there!

That is a very impressive micro mouse. I am building my first micro mouse this year for a university project!. I would love to know what type of sensors you used (IR or ToF) and if you used DC or stepper motors. Thank you!

[@MicroMouse]

Decimus uses reflective IR sensors(phototransistor and LED) to sense the walls and Coreless DC motors, it also has a fan to suck it to the ground to increase increase grip.

[@lachlancarboon7236]

@@MicroMouse Thank you for your response. Ive had a quick look at Coreless DC motors and they look very good. Do you know of any cheap ones that come with a gearbox? Through research, I also determined that ToF sensors could be a better option than IR sensors, Yet I can't seem to find any other MicroMouse that uses ToF and was curious why everyone uses IR?. Thank you!

[@MicroMouse]

The motors in Decimus are indeed expansive(getting on for £200 each i think) you don't need motors like that but it helps. another reason for the cost are the built in encoders for feedback from the wheels, this is usually one of the hardest parts to sort out. The problem with TOF sensors is speed, the IR sensors can be run at 1 kHz or faster while the tof ones only go up to about 100 Hz(unless you know otherwise) and you don't need the range they offer, 20cm is plenty.

[@Rankai22]

im prob gonna build one for a uni project aswell. How much can I expect to pay for its parts?

[@horsefeathersmcclipclopert5659]

I wish I could build things like this. This is so cool

Just start then!

You can? Go for it and don't give up.

NICE, IS THE SURFACE OF THE MAZE MADE FROM SOME SPECIAL MATERIAL TO ALLOW GOOD GRIP FOR THE CAR SO IT DOESNT SLIP?

[@MicroMouse]

NO its just blackboard paint on MDF wood, the grip is created by using a fan to suck the mouse to the floor.

[@user-pi5qj8nu7c]

Its marvelous Which hardware material are used to make this mouse

[@MicroMouse]

This mouse uses an STM32F4 processor and Faulhaber motors with a vacuum fan to increase downforce.

[@bensabraham4863]

That's so fast ....Nice job man ..floodfill?

[@MicroMouse]

Yes it uses a form of flood fill but its optimised for diagonal routes and the dynamic performance of the mouse.

[@lounes.]

was it an arduino based micromouse ?

[@MicroMouse]

This mouse uses an STM32F4 and is not programed using the Arduino framework, the processor is supported using arduino so it possible could be. Here are a couple of mice that use the Arduino nano kzbin.info/www/bejne/o6mwmIVoa9VkgsU

@@MicroMouse is there any documentation about the two robots presented in the video ? i.e hal900 and Phobos

Both are based on the UKMARSBOT here ukmars.org/projects/ukmarsbot/ and mazerunner software available here github.com/ukmars
