Walker

Thank every one for coming in the cold weather.  This week we buld the walker which is powered by a battery motor; and it is the first time they work on their own to finish the project.  The whole class went really well.  The building, socializing, and learning.  The part that gets most students messed up was when they try to connect the legs to the body.  At this age, students don’t really have a good understanding of geometry.  They need to put the legs between the gaps not twisting the other way.  It would result in breaking down.  But overall, kids did a good jod on their own.

Communication ECA Phase 2 Class 1: Insect Wheel Walker 20200108

Last week we started our Phase 2 class. Everyone did really well! This was a very complicated build with lots of detail. The build used a rotating rod in the middle of the body to spin a small arm on either side around. This arm was connected to one front and back leg. With every rotation the legs would get pulled pushed allowing the build to walk forwards on its own. Lower down by the feet (which were wheels), we used gravity controlled locks to only allow the wheel to turn in one direction allowing for maximum grip and efficiency while walking. Like I said before, VERY complicated! Everyone did awesome! Looking forward to seeing you all next class for more fun!!!!

  More partner works and tougher object to be done today.  We built a walker with a motor.  Since it is a hard one, they are working in pairs.  They show different ways of working as a group.  Some decides to work together at the same page and solve the same problems. Meanwhile some decides to work on different booklets to finish the project as quickly as possible. Once they know there would be a prize for the first one to finish, the competitiveness has risen. “It was lit” said by Roy.  The most common mistake they have made is the use of lock.  Either they forget to put one or the locks are on the wrong side of the leg. After a few pointers, they have managed to solved the problem and have fun.  They start racing and robot battling. 

Once again, IT WAS LIT

PBP Phase 1 Combined: Class 7: Walker

Today we built the walker and used the material that we learned in the past two classes about screws, worms, gears, and levers in order to make the walker walk. The kind loved playing around with their walkers almost as much as they did building them. I apologise for posting these classminutes late as my PC ran into a hardware issue and could not be booted until recently.

Communication ECA Phase II Class 2: The Walker 20180314

The model building of today is the Walker. The students built a big cricket (a legged robot) to learn the basic knowledge of mechanical balance and friction. The legged robot is comprised of four legs with a wheel at each end, it can walk with different leg lengths. The walk motions are power by one electrical motor. The motor axis kinetics are transferred by a worm gear, and then to the legs. The STEM information behind this section is the basic mechanical mechanism and concepts including a worm gear, static friction and geometrical balance of machines. All students finished the model and conducted tests by changing the legs’ length to compare the walking speed and balance.

The students had a lot of fun after finishing the model building and lab tests. They used their robot as battle robots to compete with each other. Even though we are still trying to teach the students more STEM, it works better if we can teach them with fun.

PBP Phase 1: Class 3: Power Hammer

This week we built the Power Hammer in order to understand the principles of Friction as well as Potential Energy. The students seemed to have enjoyed the activity despite a few mix ups.  In the next class we will be building a car that’s powered by a flywheel. All the students are well behaved.

PBP Phase 2: Class 3: Walker

This week we built the Walker in order to understand the principles of Levers and learn a bit about why walking can be useful. The students seemed to have enjoyed the activity however not many of them were able to finish on time due to the complex nature of the walker itself, I advise certain students to do less talking and more building.  In the next class we will be building a pulley system that will move a cart up a ramp. I ask that the parents help with cleanup as a few pieces were found to be lying around after class.
