Hello, could you please tell me what 2.86 is. If I use medium angular motor this number changes? Thanks
@why-not-bot14 күн бұрын
Hi, the value 2.86 depends on the diameter of the robot wheels and the distance between the two driving wheels. My robot has wheels of 5.6 cm diameter and distance between the wheels of 16 cm. The ratio 16/5.6 is 2.86. To turn the robot through 360 degrees the wheels will have to move by 16π cm. If you turn the motor through 360 degrees the wheels only move by 5.6π cm so you have to multiply by the ratio. I hope this explains it!

@@why-not-bot Excuse me for the second question, Sir. At minute 6:27, we can see how the robot slightly veers to the left when the junction is of that type. How could this be corrected? Perhaps by having it follow the line on the right and then, after completing the turn, making it follow the line on the left? Thank you.
@why-not-bot9 күн бұрын
@@davidezeppa384 Hi, thanks for your question. I have looked closely at the video and see what you mean. I should have followed the right side of the line here, you are correct. The kick to the left happens after the move 5.5 cm block, this block is not a line following function, just a basic movement block so I do not see a reason for the kick to the left. I still have the robot so I can look into this although it will be a few days as I am away from home at the moment. It might just be the first part of the spin turn to the left which is the next block executed! Thanks for your feedback

@why-not-bot15 күн бұрын
@leongkiungwah2653 Both models use two motors for moving the robot, one sensor for line following and one sensor to read the colours of objects. The WRO2022 robot has one motor to pick up the laundry and one to drop the laundry. The other robot has one motor to grab the blocks and one to raise/lower them. It would be great if Spike Prime had 2 more ports for sensors/motors!

Hi there I really appreciate the time you’ve put in making this video, I have one question, in the “S” ramp, when we scale the function, you have a hard-coded value of “8” could you please tell me what this number signifies. Thank you for your help.
@why-not-botАй бұрын
Hi There I will do my best to explain the value of 8. We calculate the distance travelled as Adegrees/Degrees. This varies from 0 to 1 over the distance we want to travel. The S-curve equation I have used has an input of minus infinity to plus infinity for an output of zero to one. If we use an input of minus 4 to plus 4 we use about 99% of the curve which is good enough for our ramp. So before we can use the S-ramp curve we have to convert the signal which varies from 0 to 1 into -4 to plus 4. To do this I multiply by 8 and then subtract 4. I hope I have managed to explain it! Best regards Paul

I am looking at this code as my students have found this video for an example to build code based off of this ramp up style of gyro coding. They had a question about the "20" on the set Degrees variable block (2:38) . What does the 20 signify? Size of the tire?
@why-not-botАй бұрын
Hi Timothy 20 is the factor you need to convert cm to degrees. I measured the wheel diameter as 5.6 cm, this gives a circumference of 17.59 cm. One wheel rotation is therefore 360 degrees and 17.59 cm. The factor I need is in theory 360 divided by 17.59 which is 20.46. I then programmed the robot to drive 50cm with this factor and measured the distance travelled. I had to slightly modify the factor to give me the correct result. Theory and practice are usually slightly different! The sources of error are perhaps my measurement of the wheel diameter, some wheel slip and some overshoot at the end of the 50cm run which would be speed dependent. Factor 20 gave good results and is a nice round number. I hope this answers your question, thanks for your interest!

It seems that you are using just one color sensor to follow the lines and detect the intersections. Am I right?
@why-not-bot11 ай бұрын
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.

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.
@why-not-bot Жыл бұрын
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!
