130 Make: Robotic Arms

STEP 3: ATTACHING THE ROTATING BASE

Next, we’ll continue by using five M3 bolts to connect

the base of our robotic arm onto servo 1. At this point,

it will be crucial to make sure the base component

of our robotic arm is oriented and as straight as

possible, as this will be the foundation of the entire

robotic arm, and being off by just a few degrees can

end up making a pretty significant difference to the

eventual position of our end effector.

STEP 4: MOUNTING MOTORS 2 AND 3

With our base established, we can begin building the

additional components we’ll need for the build. Next,

we need to grab two plates we’ll call the ...
