Robotics Competition, 1/25/2018

On Thursday night, January 25th, we had a great turnout for the first Robotics competition of the 2017-18 school year. Twenty-five students competed in four competitions, entering robots that were the product of imagination, innovation, and plenty of hard work.

The four competitions were "Slope Climbing Robot," "Speed Robot," "Delivery Robot," and "Table Clearing Robot." 

For the first time ever, we had two robots complete the delivery course! Iris Hennin, an 8th grader at WCS completed the course on her first try (an amazing accomplishment) with a time of 20.16 seconds. Riley Dunn and Dalton Johnstone, both 7th graders at BMS had the winning time, completing the course in 17.46 seconds. It took them five tries to finally succeed!

Three robots completed in the speed competition. Josiah Keller and Chris Swinburne, 6th and 7th graders respectively at BMS, took third place with a time of 14.55 seconds to complete the 18 foot course. Second place was Tyler McCarren, an 8th grader from WCS with a time of 7.17 seconds. The winners were Sam Taft and Alex O'Camb, both 8th graders at BMS with an extraordinarily fast time of 2.86 seconds. 

Just one robot was entered in the Slope Climbing Competition. Tyler McCarren and Eban Keach, 8th graders at WCS, built a robot that managed to climb a 55˚ slope with ease.

Finally, in the Table Clearing competition, four robots successfully completed the challenge. Riley Gale, 6th grader at WCS in 31.65 seconds, Seamus Philbrick and Sonya Viselli, 6th graders at BMS in 29.5 seconds, Lucas Martin and Nathan Goodman, 8th and 7th graders respectively at BMS in 20.96 seconds, and Cody Stewart and Severen Denyer, both 7th graders at BMS in 19.86 seconds.

Lucas Martin made two robots for the table clearing event, one that met the criterion of fitting inside a cubic foot of space, and one that fit a square foot but extended up three vertical feet. Below is a video of the "legal" robot and the "illegal" robot. We allowed Lucas to run the "illegal" 'bot as a fun demonstration. It cleared the table in just 9.8 seconds!

Congratulations to every single contestant. The spirit of friendly competition, good sportsmanship and dogged determination in the context of math, science and engineering was wonderful to see. We will be hosting the annual SUMO challenge in early May, and we hope to see you there!

Preparing to Compete!

All the pieces are in place for another great competition tonight. Students have been working tirelessly to perfect their robots, often making big differences in performance with small tweaks to both designs and programs. An 8th grader at Woolwich made sure her delivery robot was successful in its mission fifteen times in a row before packing it up for travel to Bath Middle School.

I transported all the WCS robots over to the BMS computer lab last night where they are being charged in anticipation of the competition. Mr. Seymour and I cordoned off the area with caution tape to dissuade the curious from handling the merchandise.

Tonight promises to be a lot of fun, and we hope you can make out to support the work of our robotics students. Look for a full report on the competition coming up soon!

Desktop Programming vs. Chromebook Programming

I was so excited to learn that LEGO had created a cloud-based programming environment for EV3 Mindstorms Robots. Every student in our district has a ChromeBook assigned to them in grades 3-12, so I imagined a lot of opportunity for kids to experiment with programming, even when we weren't meeting for robotics.

But not so fast...

Some of the exciting functionality of the desktop programming environment doesn't seem to exist in the ChromeBook version. Data wires, sensor blocks and math blocks are not part of the suite. What this means is the inability for students to experience concepts like amplitude, randomization and exponential changes in motor speed. It will also be difficult (impossible?) for students to conduct experiments since there are no sensor blocks.

So, while it's convenient to have the ability to program on the ChromeBooks in a pinch, we will be sticking to the desktop version for now.

Welcome to Robotics for the 2017-18 School Year!

The "brain" and "heart" of the LEGO Mindstorms Robot is the EV3 Programmable Brick. It's a combination of a small computer, control center, data manager and power output. The EV3 runs in the Linux programming environment, and has some amazing functions.

One of the first steps at the beginning of the year is to guide students as they explore the landscape of the EV3. There are four main tabs, and under each of these categories is a variety of functions. 

By navigating through the tabs it is possible to view, log and graph data input (like distance, light intensity, changes in position, etc.), control motors manually, save and organize files, connect to computers via bluetooth, and even write simple programs.

The import and output ports on the EV3 brick are differentiated by letters and numbers. Numbered ports are inputs for data from sensors. Lettered ports are outputs for energizing motors. 

You can learn a great deal about the EV3 Programmable Brick from the EV3 Manual. 

As we progress through the year, and the challenges get more complex, it will be important to have a firm understanding of the way this brick works.

The Results Are In!

This was the first year for the maze and line follower competitions, and they were both challenging, engaging, and exciting. The kids dug deep into their creativity and perseverance when presented with these tough tasks. I'm impressed by each and every one of them --those that solved the challenges as well as those who did not.  The final results for each of the competitions are below:


  3. HI BYE 67.52 SECONDS
  5. BOB 70.92 SECONDS
  7. MEH 89.73 SECONDS
  8. TEST 96.98 SECONDS
  9. ATLAS 183.58 SECONDS
  10. BRICKY 188.89 SECONDS


  4. DR. DAB-RAH 55.21 SECONDS
  5. CORNY 61.15 SECONDS

2017 RSU 1 Robotics Olympiad, June 1st

For the first time ever, RSU 1 is hosting its own Robotics Olympiad event on Thursday, June 1st in the BMS cafeteria from 6:30 to 8:30. The competition categories* are:

  • Speed Robot
  • Can Clearer
  • Walker
  • Robot Courier
All robots must fit in a 1 foot by 1 foot square. They may not grow in size by unfolding or deploying extensions during their event.


Robots are electronically timed through a straight course, 18 feet long. The robots must stay on the course to be timed. The fastest time is the winner!


Robots navigate an elevated table to clear 8 empty cans from the surface. The robot to clear all the cans in the least amount of time is the winner. All cans must be cleared and the robot must not fall off the table in order to be scored.


A robot that walks with two or more legs must move forward for three feet through a four foot wide course. The robot that walks the three feet in the shortest amount of time is the winner.


A robot must carry a small object from the course start to a target at the course end. The robot must not leave the playing field, and after depositing the object in the target, must exit the target boundary. The robot that completes the challenge in the shortest time is the winner.

Mark your calendars for what promises to be another great night of robot competition!

*The events and rules are inspired by Maine Robotics, and the work of Tom Bickford and his staff.
