Line following robots, fire fighting robots, and many other industrial robots are frequently used in many industrial applications such as for welding purpose, for changing the place or position of an object, for heating the product or material at very high temperatures, etc. Innovative robots can be used for home applications with robotic arm to switch on or off the loads, to feed physically disabled human beings, and so on. Exclusively, pick-and-place robotic arm kit is typically used for holding an object in several industrial applications. This pick-and-place robotic arm kit can be considered as a programmable robot arm. Here, in this article we discuss about how to build your own robotic arm.
How to Build Your Own Robot Kit?
The basic thing to do before proceeding to build your own robot kit is to find the application of robot for which it is intended to be used. Then, buy all the required electrical and electronics components to build robotic arm kit either offline or online. As the online marketing technology has improved a lot, even every discrete component is available online. So, we can use online shopping websites like www.edgefxkits.com to buy electrical and electronics components or project kits from our residence itself. Then, primarily download our free eBook to design electronics project on your own that will help to build your own robotic arm kit.
3 Steps to Build Robotic Arm Kit
There are three simple steps to know how to build your own robotic arm kit at home.
Step 1: Selection of Hardware Components based on the Software Design and Tested Circuit
Primarily, you need to choose the application for which the robotic arm kit is intended to be used. Thus, choose the components with appropriate ratings based on the application of robotic arm kit. After assembling the components, build an exact circuit using any available software such as Proteus or LabView to check the circuit operation in detail and to evaluate and compare the results of the robotics projects. The software designed robotic arm kit circuit experimental results can be checked to meet the intended application requirements. Furthermore, changes are made in the design of the circuit if necessary. Thus, in this way, you can analyze that the software-based design circuit, which can be realized in real time hardware or not. You can avoid the unnecessary expenses for direct practical circuit design without testing.
Step 2: Hardware Circuit Implementation based on Circuit Design using Software
The software-based designed circuit results are considered for the appropriate selection of hardware components. The PCB (Printed Circuit Board) is designed as similar to the connections of the software-based designed circuit. Then, the gathered hardware electrical and electronics components are soldered on the PCB layout obtained by following the best soldering techniques. After soldering all discrete components, the major parts like robotic arm, wheels of the robots (if any), arm grippers (soft grippers are used for robotics projects intended for diffusing explosion materials), and so on are connected to form robotic arm kit. After building the entire hardware robotics projects – here robotic arm kit project – the working of the robotic arm kit is checked and tested.
Step 3: Robotic Arm Kit’s Working and Controlling
Although, the robotic arm kit is built using the above steps, before using it in practical applications, a control system has to be developed.
Thus, you need to achieve controlling mechanism over the robotic arm kit which can be done using 8051 microcontroller along with a control circuitry.
You can easily understand the working of a robotic arm kit by considering the real-time practical project pick and place robotic arm kit.
Applications of Robotic Arm Kit
The basic robotic arm kits are frequently used for different applications such as for extinguishing fire, for soldering materials, for heating objects, for following a specific path, etc. This particular robotic arm kit finds its applications in military and defense services like diffusing bombs.
The above stated simple steps are followed to build a working pick and place robotic arm kit using all the required discrete electrical and electronics components and also major hardware components such as two DC motors, switches, battery, a piece of metal, etc. These steps of how to build robotic arm kit includes building wheels of the robot with strips, motors, and arm gripper. Soft gripper of robotic arm kit is used for some applications like diffusing bombs, etc.
This project is build to develop a pick n place robotic arm kit vehicle with a soft catching gripper. This soft catching gripper can be used to handle a bomb very safely and carefully such that it avoids dangerous explosions during the process of catching and diffusing. The pick and place robotic vehicle can be remotely controlled using RF remote control technology.
The robotic arm kit consists of servo motor that is used for angular rotations of the arm to catch items (to hold items, to release, to rotate, to place). This servomotor works on the principle of Fleming’s left hand rule and can be controlled using the microcontroller programming technique and the program used for controlling the robotic arm kit movement is shown below. Hence, it can be called as a programmable robotic arm.

The push buttons of transmitter end are used to send commands to the receiver end. These commands are used to control the movement of the robot in forward, backward, left or right directions. The four motors are interfaced to the microcontroller at receiver end. Amongst these four motors, for the movement of arm and gripper, the robotic arm kit utilizes two motors and for the robotic vehicle movement the other two motors are used.
The RF transmitter shown in the figure acts as RF remote control. If we provide proper antenna, then we can use this RF technology over a range of 200 meters (advantage of adequate range up to 200 meters). The receiver circuit of robotic arm kit decodes the encoded data that is received from the transmitter end (which is given by the robotic arm controlling person or controller). This decoded data is then fed to another microcontroller for driving DC motors through motor driver IC to perform the required task. The soft catching gripper arm is the key benefit of this robotic arm kit. This soft gripper arm can be used to avoid extra stress on the suspected object (explosive objects like bombs) for safety reasons.
In future, this robotic arm kit project can be enhanced by interfacing this kit with a wireless camera. This facilitates the robot-controlling person to view the operation of the programmable robot arm and gripper, remotely.
