Stable Reverse- Double 4 Bar Prototype

The previous two motor model worked, but wasn’t very stable. It was very difficult to control and it flexed a lot. Not really something I’d recommend going to a competition with. The main problem isn’t making the mechanism work, it is making it work with the parts available in the […]

VEX IQ reverse- double 4 bar lift

I designed this yesterday. I think it would be great to use a reverse double 4 bar for the Next Level Challenge. This one works, but it is very unstable. I’ll go back to the drawing board today. Hopefully I’ll have a functional prototype before the end of the weekend. […]

Obstacle avoiding robot

I recently started going back to projects I did a few years ago. The obstacle avoiding robot was my very first Arduino project, but looking at it on the shelf in my robot workshop, I felt that it had to be more pleasing to the eye. It really was a […]

Arduino Line Follower

A short Saturday side project I made this for fun on a Saturday morning. The parts I used were all from my recycle box, except for the digital line tracker sensor boards. If you want to make a similar project, it is quite easy and you can use almost any […]

New Robot – 101

I finally got to build a new robot. I named it 101, after the famously tall skyscraper in Taipei. As we discovered in the previous posts, the Flex robot (even after improvements) couldn’t reach high enough to pick up the bonus hubs. This wasted precious time, knocking the hub off the […]

Programming IQ

The Next Level challenge also has a programming challenge part. I did a practice run on programming in the living room today.  I wrote a fairly simple little program for the Flex robot to go pick up a hub, deliver it on a little mat and return to the starting […]

Obstacle avoidance robot

This was my first Arduino project. As you probably can see from the photos, I still needed to learn a lot of things about building robots at that time. For instance, the lead acid battery I chose was the wrong kind of battery for Arduino and also too heavy. Anyway […]

Improving Flex

The original Flex from the VEX IQ website. It is suggested as the best robot chassis to use for the 2018-2019 Vex IQ Next level Challenge. We built this robot from the instructions on the website, but found it lacking a some areas: 1: The hook design didn’t allow for […]
