Two FHS Teams going to Worlds 23!

On March 11 and 12, the Framingham High School Robotics Club hosted the Southern New England Regional High School Championship. Eighty of the best teams from Massachusetts and Connecticut attended the two-day competition at Walsh Middle School. These teams competed in the 22-23 and participated in 200 matches to determine the top 16 alliances that would go into the eliminations round.

Team 9421R – Roboty McRobotface – entered the elimination rounds in 4th place with 8 wins and 1 loss. They made it to the semifinals, and this qualified them for the World Championship. The team is made up of 12th graders CJ Crocker, Ryan McLoughlin, Brady Levensohn, Zach Dustin and Tyler Garofalo. These five students attended the Middle School World Championship in 2019 where they received the Inspire Award in their Division.

Team 9421H – Hot Sauce – was 6-3 and entered eliminations in 17th place. While they lost in the first round of eliminations, they were able to qualify for the World Championship based on their performance in the Robot Skills category. The team is made up of 10th graders: Hartej Anand, Liam Hebert, Liam Parker, Joshua Peace, Kanwardeep Randhawa, Nick Swan and Ben Zislin. This will be the first Worlds Championship for them all.

Teams from FHS Robotics have participated in the VEX Robotics World Championship in

2014, 2015, 2016, 2017, 2018, 2019 and 2020.

Framingham High School Robotics was started in 2013 by a group of six students who saw a flyer for the club and thought it might be fun. This was the same year the Walshbots started at Walsh Middle School. This year, Framingham Robotics (FHS Robotics and Walshbot)  hosted more than 300 robotics teams who participated in nine different robotics competitions, including the Middle and High School Regional Championships.

Inexpensive Graphics Tablet

 

Note: click on links will generate funds for the FHS Robotics Club. It will cost you nothing.

I have been using the Huion 2020 Kamvas 13 since we went remote and it has been great! I initially had some connection issues until I realized I need to plug it in, run the Huion Tablet driver then turn it on. In that order. Every time.

It does have this proprietary cable  (you can see it in the upper right) that plus into upper of the two USB-C ports on the tablet and then splits into two USB-A and one HDMI plug. One USB-A  plug (the red one) provides power.

Kamvas Cable

 

I found an HDMI to USB-C adapter (this one) that works well. It uses a lot of ports (and assumes you have them all).

If you look at the picture below in the lower left, it looks like you can just run a cable from the lower of the two USB-C ports to a USB-C port on your computer.  Maybe you can, but I haven’t been able to do that. The hole in the tablet for the USB-C plug is very deep and narrow and most regular plugs don’t fit in there.

Huion Cabling options

I found one USB-C extender that let me use a regular USB-C cable, but the power was flaky, it stuck out really far and it was a lot more awkward to use than the 3 in 1 cable. And, frankly, the 3-in-1 works fine, but I like the elegance of using a single USB-C cable.

I do have a document camera (the Ipevo VZ-R HDMI/USB Dual Mode 8MP Document Camera), but I rarely use it now that I have the tablet. I will use it once we are back in the building, but for remote teaching, the Huion 2020 Kamvas 13 is working great (and it’s half the price of the Ipevo VZ-R HDMI/USB Dual Mode 8MP Document Camera).

How to keep an axle from flexing

From: Jason Brett:

So with axle flex you’re usually dealing with some form of three-point beam bending. The deflection of the shaft is — as you’ve pointed out — affected by both length and thickness. The thickness comes into play as the “moment of inertia” of the beam… for a square shaft the formula is proportional to the fourth power of thickness. Doubling the thickness will result in a 2^4 increase in resistance to bending, and therefore deflection should be reduced by a factor of 16.

Length, however is a cubic factor. Reducing the unsupported length (from bearing to bearing) by a factor of two will result in an 8 fold reduction in deflection. It might actually be a bit higher than that because these formulas assume a point load and a uniform beam… your beam is thicker where the wheels are and the load is distributed across that width. But the general concept applies…. shorter is better, and cubic factors make a huge difference! Simply reducing your unsupported span from 7″ down to 5″ will give you (5/7)^3 of your current deflection… about 36%. Reduce it to 4″ and you’ll be down to 18%.

Do BOTH… reducing your unsupported shaft length to 4″ AND doubling the shaft thickness and you’ll be at 1-2% of your current deflection… assuming, of course that load remains constant. If you aren’t able to compress either the tread on the wheels, the balls, or move the support on the other side of the balls, then you’re still going to have the same amount of deflection… because something has to give somewhere! This brings up the third factor in deflection… the load. Perhaps a little less “squeeze” will be sufficient to reduce your shaft flex. Keep in mind, however, that load is only linearly proportional to deflection… you’d have to reduce the load by 50% to cut deflection in half.
