Low Cost Machine Tending Robot for Automating Indian Machine Tool

Building Industries

Scope/ Objective:

1. To establish a framework to design and develop an articulated
type industrial robot for machine tending applications suitable for
the manufacturing industries.

2. To develop two different variants of machine tending robots
with different payload capacities so as to demonstrate the The Need
potency of the methodology developed.
3. To minimize the cost of the robots so that it is affordable for The need for automation in
the Indian machine tool builders. industrial sectors is continuously
increasing, resulting in induction of

Next, the choice of drive system is initiated by estimating the drive
torques required at each link of the robot. Depending on the
estimated torque, motors and torque multipliers / gear boxes
have been finalized. A frugal approach has been adopted in the
selection of drive systems to maintain a low cost of the system,
without compromising the safety factor of design.
