I was working on my class project called “Quadruped Spider robot” which was built in 3D printer and powered by Arduino. Many obstacles came across during the project which caused a delay. The main issue was 3D printing parts which were not working in special specifications as wanted. The exact moment and programming were complicated for 3 degrees of freedom robot. Due to those issues and new to Arduino programming, it caused problems using Reverse kinematics. Finally it worked but not as wanted using hard-code. It would have been easier if know how to implement reverse kinematics.
