Mini Servo Grippers and Robotic ARM using Arduino

In the current technological scenario, application of robots is certainly not exclusive to one industry. On one hand, we find a plethora of house companion robots that aid in cleaning, dusting and other chores and on other hand, we have fully robotized vehicle assembling units. Precision, high speed and long life are a few reasons explaining there has been substantial increase in use of these electro-mechanical machines.
Out of several robotic applications, using a robotic arm is one of the most popular one. From aiding in critical surgeries to easing out heavy weight lifting, robotic arms are quite a handy apparatus. Wouldn’t it be fun to have one such robotic arm to be your assistant? If you are habitual to drilling and DIYin’, this won’t take you more than a couple of hours.

Yes, the DIY we explore today, unravels an Arduino and servo motor robotic arm which has claws that provide firm grip to hold objects. Contrary to what we usually see, the arm isn’t carved from any alloy or high quality plastic, but instead, is made out of a wooden plank. All the gears, shafts etc. that are made from wood are assembled through screws, thus creating an assembly which connects to a servo motor and an Arduino. It is the use of these easily available parts that makes this arm an easy garage project that you can make over the weekend. Furthermore, using an Arduino gives ample space to make the arm smart by the use of sensors.

If you are following this DIY and face difficulty in arranging the parts, then the internet solves the problem for you right away. The robotic arm and the gripper’s 3D printable files have been shared by the innovator along with the circuit diagram and videos that show detailed working of the arm. Enough lucrative to go ahead and give a shot, can you DIY it in just one go?
