1. The document describes two prototypes of a remote controlled vehicle for payload towing. 2. The first prototype used 3D printed gears that could not handle stress and plastic tires that lacked sufficient traction. 3. The second and final design improved on structural integrity with an aluminum chassis, acrylic base, and tougher PLA 3D printed gears while adding features like double wishbone suspension and remote control via an ESP 32 module.

2. PTRCV - Payload Towing
Remote Controlled Vehicle

3. 1st Prototype
From our 1st
prototype we tried to
understand the
pulling capacity of
the motor and
feasibility of using
3d-printed gears

4. 3-D Printed gears could
not handle the stress
Sufficient traction
wasn't available to the
tyres.
Steel Shaft of 4mm was
not durable and bended
significantly
Shortcomings:-

5. 2nd Prototype-
FINAL DESIGN

6. PARTS USED:-
For Chassis - We used aluminium Brackets
For Base - 3mm Acrylic sheet
Gears - 3-D Printed Spur Gears (Tough PLA)
Front Wishbone - 6mm Aluminium Rod
(HandCrafted)
Front steering Mechanism- 3D Printed Servo
Mount
Tyres coupling - 3D Printed coupling

Structure - made
on a 6mm
aluminium Rod
Servo

11. POWER DISTRIBUTION

12. We have used an ESP 32
to remotely control our
vehicle.
REMOTE
CONTROL
ESP 32 has a WiFi
module thus,
anyone can control
the car with their
mobile phones or
laptops
