Articulate arm robot

Sometime called Anthropomorphic arms closely resembles the human arm

Technical terms (Cont.)

Number of axes – two axes are required to reach any point in a plane; three axes are required to reach any point in space. To fully control the orientation of the end of the arm (i.e. the wrist) three more axes (yaw, pitch, and roll) are required.

Degrees of freedom(DOF)- which is usually the same as the number of axes.

Working envelope – the region of space a robot can reach.

Repeatability - how well the robot will return to a programmed position. This is not the same as accuracy. It may be that when told to go to a certain X-Y-Z position that it gets only to within 1 mm of that position. This would be its accuracy which may be improved by calibration. But if that position is taught into controller memory and each time it is sent there it returns to within 0.1 mm of the taught position then the repeatability will be within 0.1 mm.

18

Motion control – for some applications, such as simple pick-and-place assembly, the robot need merely return repeatably to a limited number of pre-taught positions. For more sophisticated applications, such as welding and finishing (spray painting), motion must be continuously controlled to follow a path in space, with controlled orientation and velocity.

Power source – some robots use electric motors, others use hydraulic actuators. The former are faster, the latter are stronger and advantageous in applications such as spray painting, where a spark could set off an explosion; however, low internal air-pressurisation of the arm can prevent ingress of flammable vapours as well as other contaminants.

Drive – some robots connect electric motors to the joints via gears; others connect the motor to the joint directly (direct drive). Using gears results in measurable 'backlash' which is free movement in an axis. Smaller robot arms frequently employ high speed, low torque DC motors, which generally require high gearing ratios; this has the disadvantage of backlash. In such cases the harmonic drive is often used.

My first Step..

Description: PC-Controlled 5-DOF Robotic Arm.

User can easily operate this robot. Operator can able to controlits direction, pause the movement, record in step mode and can control different axis simultaneously.

Diver circuit gets control signals from PC’s parallel communication port. This circuit consists of Logical Gates, Current Driver circuit. This robot has two-finger tips which can pick and place small objects. It has a special slippery contact (Electrical) that gives complete 360 degree of freedom at base and wrist of the robotic arm. Special attention had been given during manufacturing of this ARM mechanism modular so that it is possible to detach different modules like gripper, elbow, shoulder which helps in further enhancement.

With more sophisticated technology we can target education, home as well as toy market of robotics.

In the requirement analyze (RA) phase we have to list out a “software & hardware skill set” that needs to be addressed or enhanced during the education process. My dream is to design and develop an Arm or kind of robot which encapsulates these features to enhance student learning performance.

Further improvements

My Vision

I like designing and developing robot from my child hood. My own robotics career started from my home made robotic arm and my dream is to make more aesthetic, sophisticated robotic arms and a new kind of service home robots.

To achieve this goal I am constantly in search of opportunity. If a team of dedicated people with the common vision and multi disciplinary skills is available then we can definitely achieve this goal.
