Spike Prime Proportional Programs Part 1: Gyro Straight
Vložit
- čas přidán 5. 08. 2024
- This is part 1 of a 3 part series in creating proportional programs for the LEGO Spike Prime and Robot Inventor sets. This lesson will introduce you to proportional programs and show you how to create a program where the robot will run in a straight line on a gyro heading of 0.
Very informative! I made mine go straight by using the "start moving at ___" block and then multiplied the yaw by -1 and put it in a forever loop
Thank you so much you my savior, I am new to spike and coaching a team.
Super helpful. Thanks Dude!
Thank You!
amazing job Thanks a lot
Thank you
very good
Thanks! New follower
This works perfectly, however I'm trying to find out how to do this with Python instead of word blocks. I've not come across a solution that works.
How do you add a stop block or piece of code so the robot will stop after a certain amount of rotations or degrees?
You will need to go into more motors, then you can have it exit on a certain number of rotations of one of the motors.
Is there a way you can measure it by distance instead of time?
At the time of the video, I didn't have an answer, but under more motors, you can set the relative position to 0, then set your exit at a specific number of degrees on that motor using a greater than operation and that motor relative position oval.
This video is very helpful to move the robot straight. We tried this program using spike prime but ran into the issues with the timer. When our spike prime is fully charged this program works perfectly with given number of seconds for a given distance, but as it starts loosing battery power, robot starts loosing its performance and we have to tweak the timer by increasing the seconds to go for same distance or length. Could you please let us know if you see this issue with your robot and guide us in fixing the problem.
That makes sense, I have never thought about it. In classroom, it isn't much of an issue, but in competition I can see that would be a problem. You can set it to go on rotations but you need to add the extra motors and a couple of steps.
Is it possible to determine the distance by relative position?
Yes, you can set the motors to measure degrees and then set the exit on a certain number of degrees on one of the motors
I love it! But how can I measure distance instead of time? I need my robot to drive for 45 cm og I can calculate rotations. But how?

@@gibfordsrobotlab Thank you so much :)
I think you can use a relative motor position to track the distance
@@frankhe2278 You absolutely can, I figured it out a recently but haven't gotten around to that video yet.
The video looks great. Have you encountered that the robot go off on a different straight line after being disturbed? We encounter that problem a lot. Are there any ideas for fixing such a problem?
I have not had that issue with the spike prime robots yet?
We followed this exactly and our spike won't move at all! Help please, what are we missing. the motor power is at 0, when it pops up to the side and it won't allow us to change it.
without more information about what's happening, first guess is to make sure your movement motors are assigned to the correct port.
Hi Mr Gibford,
Great job. Its hard to admit it, but am an absolute beginner in FLL, I'd love to learn from you guys; especially robot programming. Please how can i contact you guys? Thanks for your kindness.
Sorry to get to you so late, I do have an email attached to this channel, Mr.Gibford@GMail.com. I don't check it a lot, but I do check on occasion. I would be happy to help however I can.
hey is there a way to make it so it goes backward
You, can set the motor power to -40 instead of 40.
@@watermelon-f6w not for spike prime im pretty sure
I have never tried, but Ethan Zhang is right, you can set the motor power to a negative value.
I have a question how do i create left turn
Cuz problem ist that if i set -30 30 it turn left after right turn but it does 180 not the 90°
@@sak0rax158 When the robot is turning left the numbers get smaller, so you need to use less than instead of greater than, and if you go past 0, then you need to use negative numbers like -90 for example.
There are also a number of videos around on the topic of a gyroscopic turn. This is a gyroscopic straight example, so you would need to use this program from driving straight, and then use gyro turns as needed for any intentional changes in direction.
I don't have the move 50% 50% block could anybody help me ?
You need to go down and add "more movement"
Didn’t work for my spike!
I think a recent update has thrown the color sensor proportional program off. I have had to go back to the basic line follower. It is still working perfectly with the gyro for me though.
