% This Animation code is for QuadCopter. Written by Jitendra Singh
%% Define design parameters
D2R = pi/180;
R2D = 180/pi;
b = 0.6; % the length of total square cover by whole body of quadcopter in meter
a = b/3; % the legth of small square base of quadcopter(b/4)
H = 0.06; % hight of drone in Z direction (4cm)
H_m = H+H/2; % hight of motor in z direction (5 cm)
r_p = b/4; % radius of propeller
%% Conversions
ro = 45*D2R; % angle by which rotate the base of quadcopter
Ri = [cos(ro) -sin(ro) 0;
sin(ro) cos(ro) 0;
0 0 1]; % rotation matrix to rotate the coordinates of base
base_co = [-a/2 a/2 a/2 -a/2; % Coordinates of Base
-a/2 -a/2 a/2 a/2;
0 0 0 0];
base = Ri*base_co; % rotate base Coordinates by 45 degree
to = linspace(0, 2*pi);
xp = r_p*cos(to);
yp = r_p*sin(to);
zp = zeros(1,length(to));
%% Define Figure plot

🏆博主优势：🌞🌞🌞博客内容尽量做到思维缜密，逻辑清晰，为了方便读者，博主专门做了一个专栏目录，整个专栏只放了一篇文章，做到极度细致，方便大家进行学习！亲民！！！还有我开了一个专栏给女朋友的，很浪漫的喔，代码学累的时候去瞧一瞧，看一看：女朋友的浪漫邂逅。有问题可以私密博主，博主看到会在第一时间回复。
👨🎓博主课外兴趣：中西方哲学，送予读者：
👨💻做科研，涉及到一个深在的思想系统，需要科研者逻辑缜密，踏实认真，但是不能只是努力，很多时候借力比努力更重要，然后还要有仰望星空的创新点和启发点。当哲学课上老师问你什么是科学，什么是电的时候，不要觉得这些问题搞笑，哲学就是追究终极问题，寻找那些不言自明只有小孩子会问的但是你却回答不出来的问题。建议读者按目录次序逐一浏览，免得骤然跌入幽暗的迷宫找不到来时的路，它不足为你揭示全部问题的答案，但若能让人胸中升起一朵朵疑云，也未尝不会酿成晚霞斑斓的别一番景致，万一它居然给你带来了一场精神世界的苦雨，那就借机洗刷一下原来存放在那儿的“真理”上的尘埃吧。
或许，雨过云收，神驰的天地更清朗.......🔎🔎🔎
