This section can be divided down into individual member projects and group projects. Here is where group members (like YOU!) can contribute stories of your projects. We can also write about our RoboMagellan build and any other future group projects.

Josh Jacob’s Meccatana Project – G15B

Josh is working on a humanoid type of robot.  He has a lot going into this creation of his.  He is merging Meccano’s Meccanoid G15 Robot with Microsoft’s Cortana AI and Intel RealSense.  Here is a link his web page for this project.

Wheel-E Meeting Will Happen

The start of the new year has been a challenge for Wheel-E.   We have run into a stretch of people’s schedules not aligning properly, which has postponed the first meeting of the year to continue work on our venerable RoboMagellan robot.  The meeting will happen one of these weeks.  The plan now is to meet on Wednesday, February 1, 2017 at AutonomouStuff starting at 5:00 PM.  (We schedule these meetings week to week as people are able and willing to attend.)

Work on Wheel-E is continuing!

For the past 6 months we have been working on an update to Wheel-E based on the Polysync framework, and programmed in C/C++.  The components are similar to Wheel-E 2.1 (as described in the 2012 RoboMagellan Update on the CIRC website), with the following changes:

  • Replaced the Netbook running Windows 7 with two Raspberry Pi 3 boards running Linux/Polysync (one RPi3 is the main controller, and the other does vision processing)
  • Replaced the Maxbotix ultrasonic sensors with a LeddarTech multi-element sensor module for obstacle detection

We are in the process of re-writing the software.  Currently the remote control functionality is working, but all of the vision and autonomous control still needs done.  Build sessions will resume January 25.

2012 RoboMagellan Update

Wheel-E V2.1 competed at the 2012 Chibots SRS RoboMagellan Competition on August 4th and won 2nd place! Several updates were made since the 2011 year including replacing the Mini ITX computer with a Dell Netbook, replacing the GPS and Compass with an ArduPilot board, and upgrading from Nimh batteries to 4S LiPoly packs. A huge thanks again to SolidWorks and MaxBotix Ultrasonic Rangefinders for their continued support of this project! While Wheel-E was able to successfully complete the course once, our other 2 runs did not go as well due to compass accuracy problems and the lack of functional object detection. We’ll return next year with these problems hopefully remedied.

RoboMagellan Update 2

Wheel-E V2.0 competed at the 2011 Chibots SRS RoboMagellan Competition on August 6th. He was well equipped with numerous upgrades including a brand-new custom chassis designed using SolidWorksMaxBotix ultrasonic rangefinders for object detection, and a new GPS unit. Wheel-E v2.0 was ultimately unable to complete the course but the CIRC team learned a great deal and is anxious to return again next year after more testing and troubleshooting. (more…)

RoboMagellan Update 1

Wheel-E v1.5 competed at the Chibots Summer RoboMagellan competition today. He put forth a valiant effort but ultimately was unable to complete the course due to GPS inaccuracies, limited obstacle detection abilities, and a nasty fall during one run which damaged the GPS receiver. Wheel-E v2.0 is already in development and will be ready for next year’s competition! (more…)

RoboMagellan Overview

The RoboMagellan competition was created by the Seattle Robotics Society in part as a low-cost alternative to the DARPA grand challenge. Intrigued by the idea of vehicles that can autonomously navigate outdoor environments, the group devised a competition in which robots navigate between GPS waypoints through a college park type environment. During their run (more…)
