Spring Rebirth

On February 17, 2014 By

It’s been a while since our last blog post … but we’re back! The team worked last semester to plan and develop our strategy for Microtransat and Sailbot 2014. Over the last couple of months we became an officially recognized club at Tufts, celebrated Tufts Community Day, and made a retractable wing sail. Now we [...]

Sailbot Finale

On June 14, 2013 By

This Thursday was the last day of Sailbot with one last race–the box course. The box course is a demonstration event aimed at showing off each boat’s autonomous ability. Officially called “Station Keeping,” the course is a 40 m x 40 m box. Each boat is allowed two timed runs and must stay within the [...]

Races for day two of Sailbot 2013 were cancelled because of inclement weather so TRST delivered their presentation to the Sailbot judges. Duncan Swain, Dominic Guri, and Joshua Prince explained our philosophy and approach to Sailbot: Because of our time constraints, we choose more conservative and reliable strategies. Rather than trying to reinvent the wheel, [...]

Sailbot Day 1

On June 11, 2013 By

Today was the first day of Sailbot 2013, and Tufts Robotic Sail Team (TRST) competed in a Navigation Test and a Fleet Race. The Navigation Test tested our boats ability to autonomously sail a windward-leeward course. The most challenging feature of the course is tacking upwind. F-dash failed to tack, and continued to sail in circles. [...]

On Sunday, Dominic Guri, Andrew Schneer, Duncan Swain, and Joshua Prince represented Tufts Robotic Sail Team during the welcome and preliminary testing day for Sailbot 2013. From morning till late afternoon, Andrew and Dominic worked on completing Arduino code to be used for sailing our boat in autonomous mode.

Manual control [...]

Maiden Voyage

On May 28, 2013 By

This Memorial Day weekend, Tufts Robotic Sail Team (TRST) started the summer right with the maiden voyage of our first robotic sail boat. This first sail tested the work we put in over the past couple weeks to build the CR-914 model. A critical milestone before we attempt autonomous sailing, Monday’s under-way in the Charles [...]

Sailbot

On May 19, 2013 By

Welcome to the TRST blog for Sailbot. Sailbot 2013 is an international robotic competition that challenges Universities, High Schools, and hobbyists to race robotic sailboats. This year, Olin College of Engineering is hosting the competition in Gloucester, MA. With a timeline of 6 weeks, we are hacking a CR-914 one [...]

GPS Testing

On May 16, 2013 By

Currently, our biggest engineering challenge is getting our GPS sensor to work. Last night Dominic and Joshua tried to read some GPS data to no avail.

We are pretty sure our problem is signal strength–we need to attach an antennae.  We are working on reviewing our code this weekend to rule out other [...]

Coding Update

On May 16, 2013 By

Our coding for the sailbot boat is underway. We are using LabView 2012 to program the Arudino that controls the boat. Dominic Guru, a sophomore majoring in Mechanical Engineering, is testing our servos using some simple code:

 

Dominic successfully controlled the servo with a potentiometer and could read both the desired angle, and [...]

The Microtransat Challenge is an international competition dedicated to the development of autonomous sailboats. The first competition started in 2006 and in 2010, Aberystwyth University and team ENSIETA competed in the first transatlantic race. Ever since, only a handful of teams have actually attempted the challenge.

Sailing across the Atlantic has never been a trivial matter, [...]
