Make: Robotic Arms

N

ow that we have a ton of great examples

for controlling two-DOF 2D robotic arms,

it’s time to take things to the next level and

assemble our first 3D robotic arm. Though this

next arm might look more complicated, most

of our code and even our inverse-kinematics

calculations will look very similar to our previous

examples. The biggest difference in our new

design is the addition of three new motors, which

will allow us to add a degree of freedom, and

control of a gripper for our end effector. Now that

we’re dealing with 3D robots, we now have three

degrees of freedom within our robotic arm.
