Project tutorial by Mako. Please log in or sign up to comment. This project is a practical robotic arm that is stable, consistent and easy to use without motor shield or sensor shield. It has a low cost. Make a simple and programmable servo arm out of readily available materials! Construction of a prototype that mimics the movements of the human arm. Project showcase by zezarandrade. Make a simple robotic arm which has master - slave control, and can record and play the moves.

Project tutorial by Harsh Dethe. A different view towards hydraulic system. This is a hydraulic system which is punched with electronics. Build and control a simple robot arm from anywhere in the world! Project tutorial by Hammad Iqbal. Robot arms are awesome! In this tutorial we explore how to control one of them using a Nunchuk and an Arduino Mega. Project tutorial by Igor Fonseca Albuquerque.

This is a low cost robotic arm with 6 axis that you can build with analog servo motors. Symbols used at two-letter coding Huang and Milenkovic have used sixteen unit of two-letter combination for robot organs. A useful organ must have an extensive sized activity skill in three dimension space; difference is that each organ is different from the other categories.

Imitation Imitation or simulation is an animation of physical activity by the help of programs which are necessary at computer atmosphere before acting a physical activity. There are advantages of testing the programs. If robot programmesare loaded to robot before testing by the help of imitation, robot can damage itself or environment. For this reason, testing robot programmes after software provides time and Money.

A good robot imitation programme could modelise the position of organs, inclinations and environment. Classification of robot imitation programs It is separated in two class as online or offline. Online programming Online programming is realized when the robot is at production position. It is used to reach the tip functionary of robot at determined point. Offline programming Programming is done before producing the robot in offline programming and robot is produced after programming.

This type of robotsare wed at repeating process. If we want to do other action with the robot, first we delete the old program and it is programmed again. Furthermore, the work has revealed the classifications of the industrial robotic arms according to unrestraint levels, power supply which is used by the robotic accelerators, control methods, sharpness grades and codification with double letters.

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. Using the same principle, we applied pressure to fluid in syringe which is transmitted to other end of tube which is connected to a syringe. This motion of the syringe is used to move the links or parts of the mechanism which are attached to respective syringes.

The slotted mechanism used in the design, increases its complexity but at the same time increases its efficiency, ability, area of coverage.

Rack and pinion mechanism used to provide rotatory motion does its work smoothly without any jerks or shocks and giving more degree of rotation and thereby increasing the area of effect. To increase overall stability and to avoid roll over or unbalancing due to torque or extra weight in the front part, suitable counter weight is used in the rear portion of the mechanism. Soap water having least compressibility and high efficiency is used as a fluid in syringes.

Syringes 10 ml — 8 Pcs. Wires Aluminium — 50 cm long 5. Wood sticks for joints and connections — 10 sticks 6. Tie — 16 7. Vinyl tubes cm 8. Paper tape 9. Glue gun with refills Fevi-quick Spray paint yellow Old battery Hydraulic Cylinder A Hydraulic cylinder also called a linear hydraulic motor is a mechanical actuator that issued to give a unidirectional force through a unidirectional stroke. It has many applications, notably in engineering vehicles.

Hydraulic Fluids Petroleum Based Synthetic fire resistant water based fire-resistant. Hydraulic cylinder as shown in fig 1. Syringe as shown in fig 2. Fluid lines are used to transfer the fluid, and fittings are used to connect the lines to the power source and the points of application. Sizes of pipe are listed by the nominal or approximate ID and the wall thickness. Sizes of tubing are listed by the actual OD and the wall thickness.

Since it determines how much fluid can pass through the line in a given time period rate of flow without loss of power due to excessive friction and heat.

The velocity of a given flow is less through a large opening than through a small opening. If the ID of the line is too small for the amount of flow, excessive turbulence and friction heat cause unnecessary power loss and overheated fluid. Vinyl tubing of different lengths. Vinyl tubing as shown in fig 3. Arms Arms is the vital part of this vehicle one is base arm in which the whole structure of the arms are steady and second is the vertical arm in which the gripper and all small arms are fixed.

Base arm as shown in fig 4. Vertical arm as shown in fig 5. Grippers Grippers are used to grasp and hold objects. The objects are generally work parts that are to be moved by the hydraulic arm. These part handling applications include machine loading and unloading, picking parts from a conveyor, and arranging parts into a pallet.

Depending on the mechanism used for the purpose of gripping they can be classified as: 1. Mechanical Grippers. Adhesive Grippers. Hooks, Scoops etc. Vacuum Cups. Magnetic Grippers. In industries, two fingers are enough for holding purposes. As most of the fingers are of replaceable type, it can be easily removed and replaced.

Mechanical gripper as shown in fig 6. Moreover, this type of grippers can be used in the part loading and unloading process in which the work parts hang from the overhead conveyors hook gripper as shown in fig 7. Chasis This is the base or a chassis for which the two arms and whole body are fixed in this base. The base is made of steel and the lower hole the motor are fixed and in the motor shaft the wheels are fixed for this reason the vehicle or the hydraulic arm are move in anywhere and the motor are operated by manually so in anywhere the we used this.

Powder coated Metal chassis for robots. Easy to mount the motors on place by using normal motor mount nut. The body contains perforated holes for easy mounting of various size circuit boards and other mechanical components. Chassis as shown in fig 8. Lever A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the location of fulcrum, load and effort, the lever is divided into three types.

It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage.

The ratio of the output force to the input force is the mechanical advantage of the lever. A lever works by reducing the amount of force needed to move an object or lift a load. A lever does this by increasing the distance through which the force acts. You will see that levers neither increase nor decrease the amount of total effort necessary.
