Hydraulic Actuated Arm Using Syringe with Motor


This project is a Prototype model of “Hydraulic Actuated Arm using Syringe with Motor”.  A robotic arm which is hydraulically operated and controlled by syringes filled with some fluid. It consists of various parts connected to each other in a pre-designed manner which are guided in a constrained way to obtain the required output. The basic concept used behind the operation is PASCAL’s LAW. This law states that when a pressure is applied at one point of a fluid contained in a constrained volume, then the pressure due to that force is equally transmitted to all the points of the fluid, which are acted upon by the same pressure.

As hydraulic pumps and pistons are too costly, complex in working and rarely available, we have put our idea in the real-life scenario using medical syringe as hydraulic piston and dc geared motor as a pump. As these are exact analogs to the actual hydraulic cylinder and a piston so we can use it as engineering prototype in this model.

Hydraulic fluid is transmitted throughout the model through syringes. Pressure is transmitted across the hydraulic arms to operate the load. In this model, syringes are used as actuators at the joints to move the parts and gripper. The popularity of hydraulic machinery is due to a large amount of power that can be transferred through small tubes and flexible hoses.

Key Words: industrial Arm, Arm, Hydraulic, Syringe, Dc Motor etc.
