Tracked Vehicle

A vehicle which once participated in IEEE Open and now is used for exhibition purposes.

Beach pollution is a problem faced by many countries in the world and Brazil is not an exception to this list. This specific problem was the main theme of the 2013 OPEN challenge.The competition demanded the team to build a robot able to recognize and collect several objects from a beach like terrain , so we developed the robot, a robot made with MDF boards attached to a car’s motor “running machine”,that can provide the ability to cruise different types of ground . Windshield engine were used and its bearings were made of nylon and machining by the team.

The tracked vehicle participated in IEEE OPEN at LARC (Latin America Robotics Competition) in 2013. The aim of the competition was to develop a beach cleaner robot. It consisted on a sand arena in which were distributed soda cans, that should be collected by the robot and taken to the garbage depot. There were also other objects – a real size mannequin, a beach chair and a beach umbrella – inserted on the arena as obstacles.

We developed a robot made with MDF boards attached to a continuous track, that can provide the ability to cruise different types of ground. Windshield cleaner engines were used and its bearings were made of nylon and machined by the team. The motors are powered by a 12 V lead battery and driven by a pair of very robust power H-bridges manufactured by the team members. It’s also equipped with a radio control module in order to be used in tests and presentations.

As far as the navigation is concerned, a computer vision algorithm was created to detect the cans, the garbage depot and the obstacles by their color and size with a Kinect sensor. With their coordinates, the vehicle could move around the arena and find the cans, in order to collect and relocate them.

Nowadays, it is no longer used for competitions, and is usually exposed at events and presentations. In those situations, an algorithm to make the robot follow a small sphere is executed, for illustrative and explanatory purposes.
