With it, simply use the "force" that exists within you to have the earbud in your hands.
Step 1: Operation
When approaching the ultrasonic sensor, it will take measurements and see if there's something close. Confirmed the presence of a nearby object, the Arduino sends a command to the servo move the rod and lift the earbud. Wait five seconds and then drops the rod.
Just train a bit to get the hang.
After all, any Jedi has gone through a training. Why would it be different with you?
Step 2: Materials:
- 1 Arduino ( programed )
- 1 USB cable for power circuit
- 1 standard servo
- 1 arm for servo
- 1 piece of wire for linking
- Wires for connections
- A piece of balsa wood, 2mm thick ( 10 x 10 cm)
- pieces of cardboard
- 6 screws, 12 washers and 6 nuts (I used what I had at home)
- a earbud and a player ( i used my ipod shuffle)
- Parts Schematic
- Awl, Glue, scissors, knife, ruler, ink, etc..
Step 4: Assembling
OBs.: I used a cardboard 0.4cm thick it was what I had at the time. Therefore, each piece was made with two pieces of cardboard, leaving them with 0.8cm thick.
In the main stem of the articulated arm, put a servo standard that makes the linking arm through a piece of metal. This shaft was reinforced with a piece of cardboard between them to sustain, as the figure.
Below is a video of the movement of the rod:
Step 5: Detachable stand
Obs: The rubber I got picked out of a reader's old CDs
