The robotic arm is of 4dof configuration. It can traverse cubic and trapezoidal trajectories forming both simple as well as complex patterns with relative ease. It can be used in the 3D printing industry.
I've used Simulink for the simulation of the robotic arm and Matlab to manipulate the DH parameters so as to create elaborate patters.
Recursive inverse kinematic algorithm has been employed as it's one of the least computationally complex ways.
Challenges we ran into
COVID pandemic was my biggest problem. Not having enough money to buy the necessary parts, I had to stick to simulations which is cool but not as fun as physical implementation.
Accomplishments that we're proud of
I've been using simulink for only a short while. This was my first projects in 3D model manipulation.
What we learned
Learned a lot about inverse kinematic algorithms
What's next for 4 DOF Robotic Arm 3D Printer
Figure out a way to program 2 arms to collaborate.
