17. 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.

19. My first Step..
Description: PC-Controlled 5-DOF Robotic Arm.
User can easily operate this robot. Operator can able to control
its 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.

22. Modular Design
We can dismantle this arm in 50 different individual
parts.

shoulder, all these parts can be reassembled within 3
minute.

26. Further improvements
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.

27. 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.
