What is Robotic Arm?

A Robotic Arm is a type of mechanical arm, usually programmable, with similar functions to a human arm.

The arm can be independent device or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. The links of the manipulator may form a kinematic chain. The term "kinematic chain of the manipulator" is called the end effector and it is similar to the human hand.

However, the term "robotic hand" is a synonym of the "robotic arm" .

Robotic arms can be used to automate the process of placing goods or products onto pallets. By automating the process, palletizing becomes more accurate, cost-effective, and predictable. The use of robotic arms also frees human workers from performing tasks that present a risk of body injury.

Why Robotic Arm Car?

Within the scope of the Erasmus + project, the idea of making a robot arm car using 3D printer technology was formed. In this regard, our students at our school had a practical training opportunity about the current industrial design robotic arm.

Robotic arm car is now used for many purposes and is used in industry for various purposes such as painting, welding, assembly etc. In addition, it is used in risky areas such as search and rescue, bomb defusing and radiation areas.

Our students working on this project had the opportunity to practice the make connections of electrical and electronic mechanical circuit elements they had learned in the industrial automation course in a real environment. Thus, they both learn by doing the subjects in the curriculum and had practice as the future technicians and engineers .

This robotic arm car plastic elements were made using 3d printer technology during our project. Other parts were made of aluminum and wood. ASB and PLA filaments were used in 3D printing.

The robot arm we built within the scope of Erasmus + project can move back and forth, right, left, up and down.

Workflow

1. Part models of Solidworks model is drawn in three dimensional program.

2. After editing the parts, the assembly section of the Solidworks version puts together all the parts.

3. The assembly of parts is carried out using mounting joints.

4. Ready-made parts can be downloaded from parts library in the Solidworks program.

5. The working system of the assembled mechanism is checked.

6. The assembly creates files with .stl extension for all the data it provides.

7. The parts formed by the G codes are created with the use of a three-dimensional printer.

8. Necessary ready-made parts (motor and fasteners) are supplied for the assembly of the parts.

9. The group assembly is mounted with fasteners with a three-dimensional printer.

10. The working system of the mechanism is checked.

Robotic hand frame

Sigma aluminum in appropriate dimensions (60x50 cm) was used in the frame of the robot arm car. These aluminum profiles were cut and made ready for assembly. Aluminum frames were combined with appropriate bolts and the frame was formed. The carrier poles of the aluminum sigma profiles were mounted and DC motor and cable connections were made. The lower connection wedges of the carrier poles were printed using a 3D Printer. 4 carrier wheels and DC Motor connections were made under the aluminum frame.
