amazing robot😃

I thought on first image of the video, that was an example or bar coding; similar to the Edison robot or Lego 8479 truck model. Maybe in next videos you can use these models as inspiration for new spike prime lessons.

Niceeeee

[@melindajennis2258]

Already seen them on youTube without having to pay for it. Nothing much more on the area I am paying for. Thought there would be a benefit of seeing much more and in more in depth for tutorials on Level 3 if I paid the subscription fee. Have not found that to be true.

I cannot find on my youtube how to stop my subscription please send me information as I want to stop it now before I am charged again.@@CreatorAcademyAustralia

Good explanation. Do you have the map drawing available to be printed?

[@pathwaysforexceptionalchil5167]

Yes I would like to stop payments to your account - how can I do that?

I could not find the wait_until function in Spike Prime 3.x and had to resort to using the while loop. I used the same concept that was presented but had to resort to using the 'while' command. Also, using -5 after finding the color was not sufficient when the angle to the colored line grew sharper. I ended up putting the wheel (associated to the sensor that found the color first) in full reverse.
#define local variables
left_wheel_status = True
right_wheel_status = True
#Check the sensors for the target color if either wheel is still moving
while left_wheel_status == True or right_wheel_status == True:
#Stop the robot if both sensors have detected the color, otherwise reverse the wheel direction while the other sensor and wheel continues to find the target color
if color_sensor.color(left_sensor) == search_color and left_wheel_status == True:
if right_wheel_status == True:
motor_pair.move_tank(motor_pair.PAIR_1, -110, 100)
else:
motor_pair.move_tank(motor_pair.PAIR_1, 0, 0)
left_wheel_status = False
if color_sensor.color(right_sensor) == search_color and right_wheel_status == True:
if left_wheel_status == True:
motor_pair.move_tank(motor_pair.PAIR_1, 100, -110)
else:
motor_pair.move_tank(motor_pair.PAIR_1, 0, 0)
right_wheel_status = False

Great work! Thanks for sharing. Garry

Um you din't conct the hub

[@melindajennis2258]

I just subscribed and think I will get out, This is old and does not work on the present coding for python. Very disappointed.

Hi! This is a tutorial for the Legacy version of SPIKE that many schools still use. You will need to follow the 3.x tutorials for the latest version of SPIKE. Check out: ruclips.net/video/s_xYXmYRBBg/видео.html Let me know if you need any help! Garry
