The chassis of this robot consists of 3D-printed pieces, which is what makes it a PrintBot. You can get hold of these pieces when you purchase a Evolution PrintBot Kit [available soon from the BQ Store] which comes with all the components included, or if you have access to a 3D printer, you can print them off yourself:
Here you can access the native project in FreeCAD. Feel free to adapt it to your taste!
Got it? Let´s get it set up then!
Although only 2 K screws are required to attach the brain board, we have used 4 distance bolts. We will now continue with the servomotors:
WARNING! The next step is crucial! It´s about calibrating the position of the mini servo, which means putting the eyes of the robot correctly in place. First attach the ultrasound sensor and the mini servo to the support pieces F and H:
Take the elongated head of the mini servo and fit it any position:
Now carefully turn the head clockwise by hand until it reaches the top!
The head can be stopped in any position. Now carefully remove the head…
…and then we fit it again to make it as aligned as possible, as you can see in the image.
Now we can join the two supports with a mini-screw and continue with assembling it.
Now it´s time to make the connections! Connect the electronic vitamins as shown in the diagram.
