ROBOTIC PROGRAMMING

DEFINITION

Robot programming is defining of desired motions so that the robot may perform them without human intervention.

Types of programming method for robot

1. Manual method

2. Walk through method (manual lead through)

3. Lead through method (on-line)

4. Off-line programming

1. Manual method :-

· In this type of method we used for small robots and for simple applications.

· It is more like setting up a machine rather than programming

· By using limit switches, mechanical stops, cams, relays for control the robot motions.

· This method mainly used for lower technology robots for short work cycles

Ex – pick and place robots

2.Walk through method :-

· This type of method programmer manually moves the arms of the robot through a motion sequence .

· Each movement will be recorded in the memory for subsequent play back during production.

· This type of method is used to spray painting and arc welding application.

3. Lead through method :-

· This method is commonly used to program robots with point to point control.

· In this a teach pendent device is used to drive the robot through its motion sequence.

· A teach pendent is small hand held device which consist of various switches and dials to control various movement of the robot.

· Each movement is recorded in the robot.

4. Off line method:-

· This type of programming method is similar to CNC program.

· The program is prepared on computer and after, program is fed to the robot memory.

· The main advantage of this method is that, the production time of robot is not lost to delay in teaching the robot a new task.

RATCHET & PAWL MECHANISM

INTRODUCTION · This type of mechanism is used in producing intermittent rotary motion from an oscillating or reciprocating motion member. · The ratchet and pawl mechanism consists of a ratchet wheel and a pawl, as shown in figure. · The ratchet consists of a round gear or linear rack with teeth. · A pawl is a spring loaded member that engages the teeth of the ratchet the teeth of ratchet is uniform. Theory of operation A ratchet consists of a round gear or linear rack with teeth. A pawl is a spring-loaded member that engages the teeth of the ratchet. The teeth are uniform, with each tooth having a moderate slope on one edge and a much steeper slope on the other edge. When the teeth are moving in the unrestricted (i.e., forward) direction , the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing on it into the depression between the teeth as it passes the tip of each tooth. When the t

Battery ignition system

Most of SI engine used battery ignition system. In this system a 6 volt or 12 volt battery used to produce spark. Passenger cars, light truck, motorcycles and large stationary engines are fitted with this system. Main Parts of battery ignition system: Battery A battery is used to provide energy for ignition. It is work as storage of energy and charged by dynamo, which is driven by engine. It converts chemical energy to electric energy. Ignition switch It is used to turn on and off the ignition system. Battery is connected to the primary winding of ignition coil by ignition switch and ballast resistor. Ballast resistor It is connected in series with primary winding to regulate current in primary winding. It is used to prevent injury due to overheating of ignition coil. It controls the current passes through primary winding. It is made by iron. Iron has property of increase electrical resistance rapidly by increase in tempera

Block diagram energy conversion in hydropower plant

Explain with the help of block diagram energy conversion in hydropower plant? A power generating station which uses the kinetic or potential energy of water for generation of an electrical energy is called hydroelectric power plant. Potential energy : when water is stored at high level it has potential energy. The potential energy is function of difference of water level between two points The difference in level of water between two points is called water head. Kinetic energy: water ,when it is in motion is known is kinetic energy. Theory of operation The water comes from the dam or reservoir through the penstock is directed on the blades of turbine runner , creating a force on the blades .since the runner is spinning ,the force acts through a distance ,in this way energy is transferred from the water flow to the turbine . The turbine is coupled with generator hence
