DESCRIPTION

ABU  Robocon

Launched in 2002, the ABU Asia-Pacific Robot Contest, or ABU  Robocon, has been providing an international stage for engineering students in the Asia-Pacific region to showcase their robot-building skills. Hosted by broadcasting units such as ABU (Asia-Pacific Broadcasting-Union) and Doordarshan, the event is televised across the region.

The winner at the national level representing the country at the international level.

Team Robocon IITR

Since the inception of our Team in 2008, we have worked on fusing the best technologies with the some of the most pragmatic and innovative ideas to come up with peerless robotic solutions to the yearly posed problem. Being pioneers of innovation and technology has been our precept and the passion for victory makes us strive for it.

We are a team of 25 robotics enthusiasts who annually participate in ABU Robocon, largest robotics competition of Asia- Pacific region. Representing IIT Roorkee, an elite engineering institute of India, we won the " Best Innovative Design " award in the country. We have already started working on the problem statement of ABU - Robocon 2019 and are very optimistic to prove our technical supremacy.

Team Robocon IIT Roorkee won the  Best Debut Team 2009.

Hardwork and our vision to achieve  something we carried on and we  achieved 9th position in year 2011

We grabbed the 5th place and "best Aesthetic award" again in 2016

Awarded with "BEST INNOVATIVE DESIGN AWARD" in ABU Robocon 2018.


TECHNICAL DETAILS

Manual robot

According to the problem statement, each team is given a few shuttlecocks and needs to

design two robots, one manual and one automatic robot. The manual robot needs to hand the

shuttlecocks to the automatic robot, which attempts to throw the shuttlecocks through the

rings (there are three rings at various heights in this game). The winner can be achieved by

points or by immediate KO if the robots successfully throw the shuttlecocks through three

rings, and for the highest ring, the shuttlecock lands on a golden cup on the opposite side.

Auto robot

The Robocon 2018 problem statement required the autonomous robot to perform a variety of

asks independently and efficiently. To achieve this, we used various sensors and control

algorithms for the accurate implementation and optimization of these tasks. The various tasks

and their implementations were:

1) Loading of normal shuttlecock from manual robot:

To load the normal shuttlecock onto the autonomous robot we used an arm-like

gripping mechanism. A high precision proximity sensor (IFM) was used to detect the

presence of the shuttlecock. The arm rotated with the help of a DC motor. The

position feedback for the arm was taken with the help of a rotary encoder (YUMO).

With the help of this feedback, a PID based control system was implemented. The end

effector was a 3-D printed gripper whose actuation was performed by a servo motor.

The rotation angle of the servo motor was hard coded. To preserve time and improve

accuracy, a limit switch was mounted onto the autonomous robot; when pressed the

autonomous robot could safely open the gripper and the loading of the shuttlecock

was complete.

2) Throwing the shuttlecock:


The shuttlecock was thrown with the help of a pneumatic based mechanism with pre-

specified pressure values for each throwing position. To control the pressure, a


pressure sensing module was used which regulated the output pressure depending on

the total input pressure and PWM signal provided. Initially, we had developed our

own pressure regulating module with the help of an analogue pressure sensor, a DC

motor and a gauge to measure the total pressure.

3) Loading of golden shuttlecock from manual robot:

A strategy to load all five golden shuttlecocks in a single transfer was employed to

save time and improve efficiency. The golden shuttlecocks were loaded onto a sliding

rail like mechanism which was controlled with the help of an encoder and DC motor.

Again, an IFM proximity sensor was used to detect that a golden shuttlecock was

ready to be thrown. To load the golden shuttlecock onto the throwing position we

used the same arm-like gripping mechanism. A high precision proximity sensor

(IFM) was used to detect the presence of the shuttlecock. The arm rotated with the

help of a DC motor. The position feedback for the arm was taken with the help of a

rotary encoder (YUMO). With the help of this feedback, a PID based control system

was implemented. The end effector was a 3-D printed gripper whose actuation was

performed by a servo motor. The rotation angle of the servo motor was hard coded.

To preserve time and improve accuracy, a limit switch was mounted onto the

autonomous robot; when pressed the autonomous robot could safely open the gripper

and the loading of the shuttlecock was complete.
