Once removed from the build plate, the parts were assembled with bolts seaparately.
On the third image of the previous row, a variant created with the 4th axis chuck attached.
The arm will be mounted on a single motor (axis A) that will rotate around the vertical axis. The other two motors will respectively lower the arm and tilt the forearm.
With those 2 orange arms assembled we proceeded bolting the two together, making the B and C axis respectively.
The range of motion of this arm isn’t comparable with 4-5 axis robots but it’s enought to do some simple pick and place of objects.
