The summer has a been a little quiet for Oryx 2.0 but this last week we were in Chicago at ASME’s IDETC Conference, because we were selected as a finalist for their Student Mechanism and Robot Design Competition. After giving a presentation and poster session about Oryx 2.0, we were announced to be the winner of the 2012 undergraduate robot design division! During this conference we realized how much great student mechanism and robot design going on around the world!
Even though we still have tasks to complete and the competition itself, today marks the end of the academic year at WPI, which also marks the completion of undergraduate degrees for Joe, Jon, Tom, and Mike. To celebrate our teams accomplishments we all took the night off to go to Buffalo Wild Wings. It was a great chance to reminisce about the work we have completed as a team, so i felt this quote was appropriate.
Today was project presentation day here at WPI. This is the day that all the seniors present their projects that they have been working on the the last year. We presented Oryx 2.0 to both the Robotics Engineering program and Mechanical Engineering department here. Oryx 2.0 was received very well by everyone it was presented to. We were awarded the Mechanical Engineering Provost’s Award, which is the highest award given by the department, which we are very excited about. We will keep you posted as we hear about the Robotics Engineering awards.
Below is a video that summarizes the project that was shown during the presentations today.
A few weeks back we were able to take the rover to Hologic (where I work) to use their FLIR Thermal IR Camera to do some thermal testing. For tests the we ran the Ubuntu stress test on the computer and ran all the drive motors at full speed for slightly more than 1 hour. In addition to recording the thermal IR video we also logged the temperature from our internal temperature sensors. The hottest components revealed by the thermal IR imaging are on the Mini-ITX motherboard and are rated to temperatures higher than what they reached during testing. Based of the data collected in extreme conditions we determined that the system will operate as desired under normal conditions without any temperature related problems.
We have spent the last several days getting the Pan-Tilt camera mast payload assembled for the rover. The camera is an Axis IP camera that was donated to the team by Axis Communications. We are currently working on the software portions of this payload and hope to be able to do some field testing with it later this week.
One feature of the rover’s rocker differencing suspension system is an 12-bit absolute encoder for position feed back. The US Digital MA3 encoder is read directly into ROS using a US Digtal QSB. The encoder is mounted in the end of the shaft with a small adapter and the cable goes through the hollow shaft.
The next phase of assembly is installing electronics and related wiring/connectors. The picture below shows the chassis with the motherboard, SSD, Wifi, dongle terminator, temperature sensor board, and liquid cooling pump. Remaining to be installing are the 4 EPOS motor controls, the 5V and 12V DC regulators, battery, contactor, and a lot of connectors.
