Firefighting Robot Competition

Fall Semester Wrap-up

Posted on

Fall semester has been a busy one for the robotics club! We kicked off our two projects for the year in September: the Firefighting Robot Competition, and the Intel Cornell Cup. For the Firefighting Robot Competition, club members are building self-driving robots that can navigate a maze using intelligent sensor systems in order to find […]

Custom Servo library

Posted on

Last night I wrote up a wrapper for I2C communication with our 2 RMCS-2203 servos. We also set up a github repository which will host and version-control all of our code. I also put our electronics schematics in there. Here’s a link to the repository so you can peek at what I’ve written: https://github.com/wincelet/tuftsrobotics_icc2015 My library […]

Final Iteration of Shield

Posted on

So I continued work on the shield and changed quite a few things from the last design. First, I decided to move the relays off board and connect them to the power supply with low gauge wire instead of routing power through the board, as I was scared of overheating the board with high current draw […]

The gripper in action!

Posted on

Take a look at our gripper doing its thing: Some notes from testing: Water is much more effective at creating negative pressure than air, since it’s non compressible. We get much better grip while also moving the syringe less distance, meaning that the linear actuator won’t have to expend very much energy to get the […]

Designing the Electronics

Posted on

Lately I’ve been busy designing a shield for the Intel Galileo which will interface all of our actuators. This includes the linear actuator and three servos. They are all controlled in different ways, all of which is handled by my board. The 2 larger servos, the RMCS-2203’s, are powered from a 12V source (not routed […]
