WALL-E

New project – Making a VEX brother for WALL-E We’re doing obstacle avoiding robots in class now, so I made a tank tread base. I soon saw it looked like this little robot’s wheels. Then I got an idea, the normal obstacle avoiding robots are so boring, let’s give this […]

Limit Switches for your Lift

I looked around on YouTube for easy solutions to my lift problem: If I wasn’t careful, the lift would go past it’s usable range and break something like a linkage or a gear would pop out. Clearly I needed to add some limit switches to turn off the motor once […]

VEX EDR Bots

I had to design some bots for display at a competition. Not real competition bots, but based on what is required for the Turning Point Competition. The first design is the Ball Puncher featured earlier and the second one is a Cap Flipper and Lift. Since the first post, the […]

My students’ first competition!

These kids only started with robotics three months ago and they have only one class per week: I haven’t counted exactly, but it amounts to about 15 hours of training. The competition was at the World Trade Center in Taipei. Have a look, they did pretty well, I’m so proud […]

VEX EDR Ball puncher

My first go at building a robot with EDR. The current EDR competition is Turning Point and one way to score points is to shoot at flags with balls. So of course I started by designing a ball puncher and a mechanism to feed it with balls. One of the […]

Unboxing the all new VEX EDR V5

SYDT, the importers and re-sellers of VEX  in Taiwan sent me this V5 to evaluate and build a robot. I’ll keep you updated on the robot, but here is the first glimpse of the awsome new V5!

Making of 4BDR (Four Bar Double Reverse)

I’ve been asked by quite a few people for a tutorial on how to make the 4 bar double reverse robot (Or rather – the Reverse- Double Four Bar). Seeing that I built it by trial and error, I didn’t take pictures at the time, but I took it apart […]

Auto-Stacker

After trying to auto stack with the 4BDR design, we decided that it was too difficult to get the bonus hubs with that robot. (It was a very nice design though). I saw a YouTube video of another auto- stacker, which led to this design. No fancy four bar lift, […]
