Arduino UNO in Bangladesh The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller.
This is a 3DPrinted robotic arm.
The design intent was to make something "easy" to make robotics arm
It uses Mini servos for driving the kinematics linkage and you can use Arduino and a decent power supply (2A) to program and drive it.
All the pieces are 3DPrinted in PLA.

This is a 3DPrinted robotic arm.
The design intent was to make something "easy" to build, and quite cheap.
It uses MG90S small servos for driving the kinematics linkage and a Pololu Mini Maestro 12 board to control the servos
All the pieces are 3DPrinted in ABS but any other material like PLA can be used
3D models in stl format can be downloaded for free from my account at Thinghiverse.

HARDWARE :
I used metric hardware and all joints rotate on M4 screws. (in alternative of M4 an #8-32 can be used)
Holes of the joints are designed quite tight. This to allow a fine adjust of their diameter using an exact drill bit.
On screws are to be used selflocking nuts. They are to be tightened till the locking of the joint, then consequently you have to loose them until you obtain a smooth movement with a low clearance between components.
On the two axis of the main arm I use a 4mm dia brass pipe, but this is not mandatory, also a threaded rod, works in the same way
SOFTWARE / FIRMWARE :
The purpose of the robot is to provide an educational tool wich allow making experiment with different control methods. I found very easy to use a Mini Maestro 12 Controller from Pololu, it is not very cheap but solve a lot of problems. You have to install drivers, a software and when connected to usb you're are immediately able to drive the servos choosing their speed and acceleration also. You can store the servo position to a sequence and when ready it can be played once or in a loop. Can also be stored in the internal script memory and it can be automatically played without computer connected.

Connect two link arms (003) to the Triangular link (006). Keep the M4 round heads screws to the inner side like shown on image and selflocking nuts to the outer side.
Connect link (003) to the rear joint of the horizontal arm (005). The lower part of the link (003) is to be connected with the vertical drive arm (002) as shown. Between the two links interpose three M4 washer, this to better align them with the vertical arm Keep the M4 round heads screws to the inner side and self locking nuts outside.
Connect now the two preassembled links to the forward drive arm (004). Punt in position horizontal arm (005) and triangular link (006) aligned with the upper connection of the forward drive arm (004). Insert the dia 4 mm brass pipe crossing all the parts and fix it with the M3x30 screw, locked by the nut on the other side. Verify the freedom of movement and If everything is ok, proceed to the next step. .
Be sure that the servo is in the neutral position than install the double arm horn on the splined shaft keeping the arms parallel to the servo body Insert the horn inside the housing below the round plate and fix the servo to the plate using one of the two long screw supplied with the servo (the small one in too short due to the thickness of round plate) .
Put in position the base between the two shoulder on the plate and attach together using the two M3 screws and nuts. There two hexagonal housing below, so nuts will be kept in position during tightening
Align the servo and introduce the wiring in the central part of the basement. Gently pull the wire to make it straight while continue to push in it housing the servo The wire is then kept in position making it pass through a frontal hole .
Attach the servo to the claw support using the two self tapping screws supplied with the servo. Keep the output shaft forward.
Insert the horn in the driving gear, then attach the horn at the splined servo shaft using the supplied screw The horn has to be aligned forward with the servo in neutral position. Cut the exceeding part of the horn from gear using a cutter.
Insert an M3 screw in the central hole connect it to the claw support then tight the self locking nut checking the freedom of movement.
Insert the two pin of the driven gear into the dedicated holes on the left finger The driven gear has also a shoulder that has to be aligned with the lateral side of the finger. If you find difficulties coupling them, reduce interference using a file. Once coupled insert an M3 screw in the central hole and attach the finger to the claw support Now the gripper is ready to be installed on the horizontal arm of the EEzybot Verify freedom of movement of the gripper manually or using a servo tester
Video on YouTube. .
Now we have the three main sub assembly ready to be connected each other. Next step we will join the base with the main arms
To join the base with the main arms align the axis of the parts and insert from one side the brass pipe 24mm long. Also the short arm of the servo that drive the vertical movement has to be supported by the brass pipe as shown on the pictures. Check the freedom of movement .
Is time now to install the servo that drive the vertical movement of the arm. Put in the dedicate receptacles two M3x10 hex screw. The servo has to be in the neutral position with the horn at 90 degrees on the right side with the press plate (009) installed (Make the wiring pass through the dedicated enlargment). Introduce the servo angled in the square seat on the base plate and slide the horn in the shaped housing of the arm that drives the vertical movement. Fixt the press plate against the servo using two M3 nuts .
Sequence for the forward&backward driving servo is similar to the previous. In this case the servo horn has to be installed with the servo in neutral condition aligned vertically..
attach the latest link to the fixed arm on the rear side of the base using a M4x20 a washer and a selflocking nut
The last assembly step is to join the gripper to the horizontal arm as shown on the picture..

This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances!
