Trossen Robotics Contest #9 Winners!

Thursday, January 10th, 2013

2012 has come and gone, and its finally time to announce the winners for the Ninth Trossen Robotics Community Contest! There were a lot of amazing entries, but six of them battled to the top to win our contest. Check out the end of this post for videos of all of our winners in action.

Sixth Place – OARC Rover by Yosheli

The Obstacle Avoiding & Remote Controlled Rover (or the OARC Rover) is a great little project by Yosheli. It has everything you need for a roving robot – a drive system (4 DC motors with encoders controlling 2 treads), a distance sensor (an ultrasonic range sensor), wireless communication(XBees) and a main processing unit (an Arduino Mega).

This robot has a two modes of operation – the first is direct remote control via a custom wireless controller. The second mode is a purely autonomous one. The OARC Rover will go forward until it detects an obstacle – at which point it will move to avoid the obstacle. To help overcome the limits of the ultrasonic sensor, Yosheli mounted the sensor on a pan servo, enabling the robot to get better readings on curved surfaces. This panning motion also gives this little robot a lot of character.

The idea of an obstacle avoiding robot certainly isn’t anything new, but its a great example of how many problems you need to solve when building a basic robot. Yosheli gets points for overcoming these obstacles on his first fully fledged Arduino Project

Yosheli will be receiving one of our RoboTurret Vision Tracking Starter Kits.

Fifth Place – Maxwell by Lnxfergy

Maxwell is lnxfergy’s Mobile Manipulator Robot. This robot can map a room and traverse the room based on that map. Then it can use its custom arm and manipulator to pick up objects and interact with the room. The latest version of Maxwell even has a linear actuator to move the arm up and down, allowing it to pick up things from the floor as well as table-height objects.

Maxwell’s arm is comprised of 2 EX-106s, 2 RX-64s and 3 AX-12s. Lnxfergy’s did a lot of work in ROS to get his custom manipulator running properly, which is a great thing for the robot community. Lnxfergy’s is commited to open source projects and his work in open source robotics has been the basis for robot after robot in the comunity. We absolutely love that Lnxfergy has made all of Maxwell’s code available. Check out this thread post for mor information about Maxwell.

Lnxfergy will also be receiving one of our RoboTurret Vision Tracking Starter Kits.
