Introduction

The UMA Robo Rescue Team is a group of students specialized in various sectors  that have joined with the objective of the conception and creation of a rescue robot capable of participating on the International Robocup Robot Rescue League.

The first competition took place in 1997 with the objective promoting the development and creation of new technologies using one of the most popular sports in the world, soccer, and and for this they set a goal that by the year 2050 they would have a team of humanoid robots capable of competing and winning against the last FIFA team champion.

Since then the competition has branched out in many different sectors like robots for domestic use, for industrial purposes and for rescue purposes.


Prototypes


We started our project developing two prototypes in parallel. Here are some renders of some basic CAD models of the initially proposed designs.

In the end we opted for a design based on a central chassis with an independent suspension system with six wheels. The first idea was using two motors (one for each three wheels) with a transmission mechanism but, eventually, we choose the option of using integrated motors in rims, also known as ‘hub motors’.

For the final design we have created a unibody chasis made of aluminium to which we are going to join suspension arms also fabricated from aluminium.

We are using an independent steering system for the front and back wheels controlled by four servomotors.

In order to participate in the ability test, we are going to implement a 6-axis robotic arm.

The control system of our rescue robot is based on ROS. A mini pc is responsible for coordinating all of the processes by connecting to arduinos DUE, Nano and MEGA, which control the sensors and actuators. We will communicate with the robot wirelessly.

To overcome any obstacle it has 6 motorized wheels and 4 Dymamixel servomotors to steer the 4 corner wheels, to be able to change the direction while moving or to turn on itself.

The installed sensors are:
– Three RGBD cameras to observe the environment of the robot and know its proximity.
– Light and color sensors with a measuring range of approximately 10mm.
CO2 detector compatible with arduino
– Microphone
– Speakers
– LED lighting
– High resolution thermal camera

These sensors are divided into different modules that are controlled separately to receive data like checking CO2 levels in the environment, noise levels or brightness.
