Here are the steps to solve this using the algebraic approach with homogeneous transformations:
1) Start with the identity matrix for the initial frame:
H0 = [[1, 0, 0, 0],
[0, 1, 0, 0],
[0, 0, 1, 0],
[0, 0, 0, 1]]
2) Apply the first rotation about Z by angle θ1:

Industrial robots can be programmed using various methods including manual, walk-through, lead-through, and offline programming. The manual and walk-through methods involve physically moving the robot arm to desired positions which are then recorded for playback. Lead-through uses a teaching pendant to power-drive the robot through points. Offline programming prepares textual programs entered later without production delays. Proper programming allows robots to perform tasks like welding, assembly, and material handling quickly and precisely.

EV Charging at Multifamily Properties by Kevin Donnelly
introduction to robotics and embedded systems
1. Introduction to Robotics
A common view : Robots as
Humanoids
We will be studying Industrial manipulator
type Robots.
2. Agenda
• Introduction to Robotics
• Classification of Robots
• Robot accessories
• Robot coordinates
• Work volumes and Reference Frames
• Robot Programming
• Robot Applications in Lean Mfg.
3. Robotics Timeline
• 1922 Czech author Karel Capek wrote a story called
Rossum’s Universal Robots and introduced the
word “Rabota”(meaning worker)
• 1954 George Devol developed the first
programmable Robot.
• 1955 Denavit and Hartenberg developed the
homogenous transformation matrices
• 1962 Unimation was formed, first industrial Robots
appeared.
• 1973 Cincinnati Milacron introduced the T3 model
robot, which became very popular in industry.
• 1990 Cincinnati Milacron was acquired by ABB
4. Robot Classification
The following is the classification of Robots according to the
Robotics Institute of America
• Variable-Sequence Robot : A device that performs the
successive stages of a task according to a predetermined
method easy to modify
• Playback Robot :A human operator performs the task
manually by leading the Robot
• Numerical Control Robot : The operator supplies the
movement program rather than teaching it the task
manually.
• Intelligent Robot : A robot with the means to understand its
environment and the ability to successfully complete a task
despite changes to the environment.
5. ROBOT
• Defined by Robotics Industry Association
(RIA) as
– a re-programmable, multifunctional manipulator
designed to move material, parts, tools or
specialized devices through variable programmed
motion for a variety of tasks
• possess certain anthropomorphic
characteristics
– mechanical arm
– sensors to respond to input
– Intelligence to make decisions
6. Robot Accessories
A Robot is a system, consists of the following elements, which
are integrated to form a whole:
• Manipulator / Rover : This is the main body of the Robot and
consists of links, joints and structural elements of the Robot.
• End Effector : This is the part that generally handles objects,
makes connection to other machines, or performs the
required tasks.
It can vary in size and complexity from a endeffector on the
space shuttle to a small gripper
7. Accessories
• Acutators : Actuators are the muscles of the
manipulators. Common types of actuators are
servomotors, stepper motors, pneumatic cylinders etc.
• Sensors : Sensors are used to collect information about
the internal state of the robot or to communicate with
the outside environment. Robots are often equipped
with external sensory devices such as a vision system,
touch and tactile sensors etc which help to
communicate with the environment
• Controller : The controller receives data from the
computer, controls the motions of the actuator and
coordinates these motions with the sensory feedback
information.
8. Robot Configurations
Some of the commonly used configurations in Robotics are
• Cartesian/Rectangular Gantry(3P) : These Robots are made of 3
Linear joints that orient the end effector, which are usually followed
by additional revolute joints.
14. Robot Configurations (cont’d)
• Articulated/anthropomorphic(3R) :An articulated robot’s joints are
all revolute, similar to a human’s arm.
15. Robot Configurations (cont’d)
• Selective Compliance Assembly Robot Arm (SCARA) (2R1P):
They have two revolute joints that are parallel and allow the Robot to
move in a horizontal plane, plus an additional prismatic joint that
moves vertically
17. Reference Frames
• World Reference Frame which is a universal coordinate frame, as
defined by the x-y-z axes. In this case the joints of the robot move
simultaneously so as to create motions along the three major axes.
• Joint Reference Frame which is used to specify movements of each
individual joint of the Robot. In this case each joint may be accessed
individually and thus only one joint moves at a time.
• Tool Reference Frame which specifies the movements of the Robots
hand relative to the frame attached to the hand. The x’,y’and z’ axes
attached to the hand define the motions of the hand relative to this
local frame. All joints of the Robot move simultaneously to create
coordinated motions about the Tool frame.
19. Work Envelope concept
• Depending on the configuration and size of the
links and wrist joints, robots can reach a
collection of points called a Workspace.
• Alternately Workspace may be found empirically,
by moving each joint through its range of
motions and combining all space it can reach
and subtracting what space it cannot reach
22. Exercise
Readiness Assessment Test A.K.A. RAT
AS A INDIVIDUAL, prepare a
detailed response for the following
Readiness Assessment test
What type of Robot Configuration does the
ABB 140 Robot have?
Can you find out its Work
Space?
23. WRIST
• typically has 3 degrees of freedom
– Roll involves rotating the wrist about the arm
axis
– Pitch up-down rotation of the wrist
– Yaw left-right rotation of the wrist
• End effector is mounted on the wrist
25. 25
CONTROL METHODS
• Non Servo Control
– implemented by setting limits or mechanical
stops for each joint and sequencing the
actuation of each joint to accomplish the cycle
– end point robot, limited sequence robot, bang-
bang robot
– No control over the motion at the intermediate
points, only end points are known
26. • Programming accomplished by
– setting desired sequence of moves
– adjusting end stops for each axis accordingly
– the sequence of moves is controlled by a
“squencer”, which uses feedback received from
the end stops to index to next step in the program
• Low cost and easy to maintain, reliable
• relatively high speed
• repeatability of up to 0.01 inch
• limited flexibility
• typically hydraulic, pneumatic drives
27. • Servo Control
– Point to point Control
– Continuous Path Control
• Closed Loop control used to monitor
position, velocity (other variables) of
each joint
28. Point-to-Point Control
• Only the end points are programmed, the
path used to connect the end points are
computed by the controller
• user can control velocity, and may permit
linear or piece wise linear motion
• Feedback control is used during motion to
ascertain that individual joints have
achieved desired location
29. • Often used hydraulic drives, recent trend
towards servomotors
• loads up to 500lb and large reach
• Applications
– pick and place type operations
– palletizing
– machine loading
30. Continuous Path Controlled
• in addition to the control over the
endpoints, the path taken by the end
effector can be controlled
• Path is controlled by manipulating the
joints throughout the entire motion, via
closed loop control
• Applications:
– spray painting, polishing, grinding, arc welding
31. ROBOT PROGRAMMING
• Typically performed using one of the
following
– On line
• teach pendant
• lead through programming
– Off line
• robot programming languages
• task level programming
32. Use of Teach Pendant
• hand held device with switches used to
control the robot motions
• End points are recorded in controller
memory
• sequentially played back to execute robot
actions
• trajectory determined by robot controller
• suited for point to point control applications
33. • Easy to use, no special programming skills
required
• Useful when programming robots for wide
range of repetitive tasks for long
production runs
• RAPID
34. Lead Through Programming
• lead the robot physically through the
required sequence of motions
• trajectory and endpoints are recorded,
using a sampling routine which records
points at 60-80 times a second
• when played back results in a smooth
continuous motion
• large memory requirements
35. Programming Languages
• Motivation
– need to interface robot control system to
external sensors, to provide “real time”
changes based on sensory equipment
– computing based on geometry of environment
