2. INTRODUCTION
• Trolley is built in a way to carry industrial raw materials, unfinished
goods, and other components which are large in size and heavy in weight.

3. Industrial Observation/Survey
 In the begining of work, we visited the two industry in Rajkot which
manufactures the mini tractors, in both the company we seen almost
same problem arise in their manufacturing unit.
 We observe that in manufacturing unit there are many difficulties are
arise like loading and unloading of the material, cleanliness,
maintenance, etc..
 The assembly line of both the companys are using the rail-track based
trolley while assembling their products. Following are the two companys
at where we visited and found the problem are:
1. Captain Tractors
2. ADICO Escorts Agri Equipments

6. EXISTING CONDITION
• According to plant layout there are many components are present for
assembling one product. So there is some limited amount of components
are present at each workbench.
• In this assembly unit some persons are only for supplying the material at
different places via manual trolley.
• If the person has to transfer a material from one workbench to other
workbench they have to cross the rail tracks by lifting the trolley which
is difficult.

7. LITERATURE SURVEY - 1
Research Paper : Oyejide, O.J. and Okwu, M.O. (2020) “Development of Sensor
Controlled Convertible Cart-Trolley,” Procedia CIRP, 91(2020), pp. 71–79
Purpose Design/Methodology Findings
To development a flexible
and intelligent sensor
controlled convertible cart-
trolley to support physical
distribution of goods.
The unique design consists
of three mechanisms,
designed such that: when
stretched, the system turns
to a cart; when tilted it turns
to incline cart with flat plate
attached to make payloads
stable and when folded it
turns to a trolley
Handling and transporting
of materials are usually
done using manually
operated trolleys. Such
practice could be time
consuming and laborious.

8. LITERATURE SURVEY - 2
Research Paper : Varghesea, B.B. (2020) “SARGoT:Smart Autonomous Robotic
Goods Transporter,” Materials Today: Proceedings 24, pp. 2030–2035.
Purpose Design/Methodology Findings
Robots are being developed
for various purposes to
accomplish many tasks which
seem to be too complex for
humans. Using robots, for
industrial purpose have been
excellent in terms of speed
and efficiency of doing
required tasks compared to
that of humans.
This robot has got mainly
three features and they are:
Path-Tracking, Avoiding
Collision, Loading and
Unloading heavy industrial
goods.
Building an industrial
robot with moderate
Speed, good efficiency in
loading and unloading
purpose within a short
time to ease human
suffering has been the
main objective of this
paper.

9. LITERATURE SURVEY - 3
Research Paper : Gunawana, A.S. (2019) “Development of Smart Trolley System
Based on Android Smartphone Sensors,” Procedia Computer Science 157 , pp. 629–
637.
Purpose Design/Methodology Findings
Our goal is to develop an
automatic moving trolley
with smart shopping devices
to solve the problem of
inconvenience and time
wasted for customers who
want to find the desired
product in the store by using
the traditional shopping
trolley.
This paper presents the
hardware and software design
of a smart trolley system.
Our smart trolley used
microcontroller and Android
smartphone as sensors and
controller. The trolley is
modeled as a two-wheeled
mobile robot.
Our smart trolley system
based on Navisens
framework can move and
show its location to the
user.

10. OBJECTIVES
To achieve the mobility & free working space in the plant for
workers
To reduce the man power
Obstacles on the track are efficiently identified.
To Increase the Flexibilty of plant in terms of material handling

11. INTRODUCTION TO SENSOR CONTROLLED
TROLLEY
• A sensor controlled trolley which follows a certain path with
the help of sensors.
• A basic sensor controlled trolley can consist of a base structure,
4 wheels, sensors, controller, drives & battery.
• As shown in layout, if we remove the rail-tracks from the
assembly line and implement the Path tracking trolley then lots
of difficulty will solve & it will lead to increase free working
space in plant.

12. • To reduce the human effort, by using the sensor controlled
trolley.
• Instead of railtracks, put the path (which is sense by the
sensors) so the brooming and cleaning is done easily.
• Operater of material handling device can easily transfer the
material no need to lift up the cart/wagon.
• Free working space is obtained, and heavy objects like Engines,
Engines heads, etc... can be transfer in bulk and even the
vehicle can easily work for transfering the heavy objects.

14. Sensors
• It is a device that detects or measures any physical parameter of
our environment and converts it into electric signals.
• We are using two different sensors i) IR sensor and ii)
Ultrasonic sensor

15. CONTROLLER
• Arduino Uno is a micro-controller.
It has 14 digital input/output pins, 6
analog inputs, a USB connection, a
power jack, and a reset button. It
contains everything needed to
support the micro-controller; simply
connect it to a computer with a USB
cable or power it with a AC-to-DC
adapter or battery to get started.

16. DRIVERS
• This Arduino compatible motor
Driver shield is a full-featured
products that it can be used to
drive 4 DC motor or two 4-wire
stepper and two 5v servo. It
drive the DC motor and stepper
with the L293D,and it drive the
servo with Arduino pin9 and
pin10.

17. BATTERY
• An electric battery is a source of electric power consisting of
one or more electrochemical cells with external connections for
powering electrical devices. When a battery is supplying power,
its positive terminal is the cathode and its negative terminal is
the anode.

18. GEAR MOTORS
• 200 RPM Single Shaft L- Shaped Motor
• Shaft length: 7 mm
• Motor Design: L-Shaped
• Shaft Diameter: 5.5 mm
• Size: 55 x 48 x 23 mm.
• Operating Voltage: 3 to 12V
• Current: 40-180mA
• RPM: 200 rpm
• Output Torque: 0.55 kg cm.

19. DESIGN CONSIDERATION OF TROLLEY
STRUCTURE
• As seen in the problem type of railtrack used is narrow gauge.
• The standard dimensions of narrow gauge is 0.762m or 762mm
in width
• For making the prototype we reduce the dimension by scale of
1:4 ( 762/4 = 190.5mm or 19cm width of trolley )
• Length of the trolley is design on basis of maximum length of
assembly.
• As from the product list the maximum dimensions of assembly
is 2884mm.

20. • To get the prototype length we reduce the dimension by scale of
1:9 ( 2884/9 = 300mm or 30cm length of trolley )
30 cm
19 cm
