Hello, sorry for my poor english
Your article is really inspiring
I have learnt pid controller few years before and your article still teaches me a lot.
I am working a tough project about ev3 and i have couple of troublesome questions to ask:
First, the project require my light sensors place in a high position (i think is about above ground) and as you know, light sensor doesnt work well in this height, it only give me about 25 degree range(from white to black). Eventhough i am using two light sensors pid follower(e=s1-s2+sensorDiff), it still cannot work well(swing). I have tuned the pid constant for long time and it still doesnt work. So i want to ask do you think it ia possible to make pid controller work well under a small range of light value? If yes, what method you would suggest me to tune the pid constane?=)
Moreover, for this strange problem, i have some idea but i am not sure about the answer.
1. How does the distance between sensor and wheel(i am using the most commom big wheel) affect the performaoine of the robot?
the integral part, instead of multplying the integral error by . i reset it to zero when the error is in the range of -1 to 1. What is the difference between this two methods and, which method do you think it is more suitable to my case?
Sorry for a long comment with poor english =p hope you can reply me soon thankyou!
If you end up finding Vault 112 before visiting Three Dog at GNR building plaza , this entire quest will be marked as completed. If you make it to the building, you'll still encounter all the super mutants (including the behemoth) with no Brotherhood of Steel soldiers in sight. (This will also happen if you speak to Li or retrieve the Journals first). The door to GNR will be locked but if you use the intercom after the mutants have all been killed, the Brotherhood of Steel soldiers stationed inside will let you in. You can then speak to Three Dog and get the achievement for Following in His Footsteps. Additionally, he'll offer you the Galaxy News Radio quest in exchange for the key and coordinates to Hamilton's Hideaway .
