WRO 2022 Senior Full Points
Переглядів 2,7 тис.9 місяців тому
The Spike Prime Robot first picks up two water containers then visits each hospital ward in turn. Either the water is placed in the ward or the ball game is played as specified by the marker blocks. Any laundry is picked up and the laundry colour saved in a list so that it can later be deposited in the right place.

Hi, you asked if I am located in Australia. I am a long way from there, in Switzerland! How about you?
Excellence explanation and great video as always. Can you make a video about pros and cons of using distance sensor and touch/force sensor? I don't see people use those sensor much during competition.
Hi, thanks for your comments! It's true, you don't see much use of force sensors in competitions, you could use one to tell when you have reached the side of the table for example. Is this what you have in mind? Have you tried using one yourself?
@@why-not-bot yeah, without the touch/force sensor, you have to measure the distance to reach a object or destination point (because there's no line lead to that object). Is this the technique you usually use in the competition? This requires multiple tries and fine tune, doesn't it?
@@why-not-bot do you have a video about motor simulation? e.g one motor for many actions likes grab, lift ...
Hi again I have sometimes used one motor to do two things like lift, grab etc. It is not easy to do more than two things because both operate at the same time and both will have to have about the same number of motor rotations. It is something I have often thought about, if I have any new ideas I will definitely make a video!
@@why-not-bot thanks in advance. may I ask if you're located in Australia?
Thanks for your encouragement!
Великолепная работа!!! Спасибо)
Amazing!! Btw yes using 2 wheels is better as the surface area is more and provides friction. But think u should have added a frame around those wheels to reduce variability in movement for competition bots.
Thanks for your comment! I also think now that the double wheels are better, the robot has to move fairly heavy boats around and the grip will be better. There will be less slip and uncertainty in the movements. I am not sure about a frame around the wheels, do you have experience of this?
can you make a video for build instruction please. thank you and looking forward to your amazing videos in the future.
Thanks for your kind words! I was hoping the video shows enough information to build the robot, a large part of the enjoyment is making your own design - it doesn't have to be identical!
I want to write to turn right. and how to tag extension lines?
I am sorry but I don't understand what you mean! The video is about optimising a line follower.
Thanks, glad you found it cool!
Очень круто!! Спасибо!!
Why my robot can't rotate?
@@kwingdragon5218 Hi KD I need more Information to help you! Send a video or program to my email pablocutler@gmail.com
Can you give me some more information on the problem?
@@why-not-bot Like the robot can't rotate in a curve line if it detects and it can't also do sharp turns
Tkwingdragon5218 To do sharp turns you probably need a turn my word where you specify the angle you want to turn. Send me a video or program and maybe I can help!
Sended already @@why-not-bot
Nice video !! Can we see the blocks programming ??
It is just a conventional proportional line follower! Is this what you want to see?
@@why-not-bot yesss pleaseee 🙏🏾
what's the height of 2 units?
what I mean by a unit is the distance between 2 lego studs which is 8mm. So 2 studs is 16mm. You could mount a sensor at for example 1.5 studs height, but you would have to make some kind of adjustable sliding mechanism rather than just fitting the sensor normally.
@@why-not-bot can you make a video on how to create an array
I am looking into this!
Thank you so much! I've learned a lot from you and also I improved your program by using a PD controller
I would be interested to see what improvement you achieved! Did you have a delay time in your PD algorithm to define how many times per second you execute it?
@@why-not-bot I didn't put a delay time
could I look at your PD algorithm? my email is pablocutler@gmail.com
Great video, thanks for the in-depth analysis! Just to clarify, at 2:35 just one of the sensors is following the line?
Thanks for watching, yes just one sensor is used there.
can you make tutorial for the robot design?thanks
It is a really simple robot, just the hub mounted on a blue frame with a motor on each side and a castor ball back and front!
Great . Can you provide lessons on arrays (list) and how to use them in the challenge
Which challenge do you mean? WRO?
@@why-not-bot Yes
@@why-not-bot yes
@@why-not-bot Yes, is it possible?
I did use some list features in the WRO2022 senior (hospital wards) to memorise the laundry, is this the kind of thing you are interested in?
This is an incredible design Pablo. I have sent you and email, I hope you read it. Thank you
Hi Gretchen, I hope to be more active on the channel now and will soon make some new videos! Thanks for your interest.
Great design. are you using Python here?
Hi Gretchen I am not using python, just the scratch blocks. You can do quite a lot with them especially if you develop some good My Blocks! Best regards Paul
Awesome! Can you share with design in details ? 🔥
I will do a new video soon with more information on the robot and the programming.
can you do a video on how you program? your metodology please
I hope to be more active on the channel and will do a new video soon.
@@why-not-bot keep up the good work
Thanks for the encouragement, I will do my best!
Thanks for the encouragement!
i really liked it. Do you have any building instructions for it
Hi! Unfortunately there are no building instructions, I just made it up as I tried to carry out the tasks! I have quite a few photos which I will make into a video .Best regards!
Hocam merhaba projeleriniz için yapim aşamaları dokümanı var mıdır? Emeğine sağlık
Hi Omer I do not have any building instructions as I just built the robot piece by piece to carry out the tasks required. I have quite a few photos which I could make into a video and put on UA-cam. Best regards
It seems that you are using just one color sensor to follow the lines and detect the intersections. Am I right?
You are correct it would be nice to have two sensors, but as we know, spike only has 6 ports. I used the line follower for a defined distance so that I could stop using it just before a junction and switch to yaw control over the junction and avoid a bump. If I want to stop at a junction, I stop using the line follower just before the junction and switch to yaw control. I then use the color sensor to detect the junction and stop. This is better than using line follow up to the junction as the junction will disturb the line follower.
Can you upload details of design ?
I only have photos from various angles, I could put them in a video and upload it!
Thank you for Video! Can you show me the robot build?
Hi, I don't have details on how to build the robot I just developed it and modified it as I tried to carry out the tasks. I have taken photos and will make a video with them soon!
Can I have the program for this robot
I intend to be more active on the channel now, thanky for your interest!
Great work man I hope you can share the tutorial of building the robot instruction
I intend to be more active on the channel now, thanks for your interest!
How does the robot detect if it hast to stop at a line crossing the one folowed? Or it doesn't?If I understand it right it's not possible only using 1 color sensor facing down.
Hi, if I want the robot to stop at a line crossing the one it is following I use a MyBlock which does line following inside a repeat until command. As I only have one light sensor for line following, I repeat until the color sensor is black. If I don't want the robot to stop I use a different MyBlock which line follows for a defined time or a defined distance. This will give a wobble when the line is crossed which is not a problem if the robot is fast enough. Alternatively I just drive straight without line following for a few cm over the line. I hope this answers your question!
Can you please make a build guide for the arm?
Sorry for late reply, I do not have a build guide for the arm, just a few photos and a short video. I will add the video soon.
good idea
Thank you! Cheers!
Do u have Instagram?
I intend to be more active on the channel now, thanks for your interest!
i have the question this is python?
Sorry for late reply! I have been looking at Python, but so far I have only used the Lego Scratch programming.
Great work man, I hope you will share the instructions after the competition.
I will be making a new video soon!
I sended you email
