Surprising Every Step of the Way

I tricked some relatives into getting me the Liebherr Excavator for a major holiday fully expecting either a smarter than average Power Functions or dumber than an average Mindstorms experience. I also expected a lot of Bluetooth headaches.

What I got was nothing short of phenomenal. Connections were flawless and painless. Firmware updates were transparent—if long. The model testing along the way barely hinted at what was possible. Ultimately the total package completely blindsided me, but in the best way.

The app is flawless: it holds your hand just enough while encouraging exploration through its achievements and rewards. Don’t like multi-touch? They’ve got you covered. While I’d rather use a text editor to program it, you can get somewhat sophisticated dragging control blocks around. And they really undersell the hardware! The app shows you the tilt of the model, updating in real time—but there’s no mention of an accelerometer or gravity sensor anywhere. What other things can it do? I’m certainly curious to get the other Control+ models now!

I can’t go 5 stars, though, because the app seems hard-coded for three LEGO models. But LEGO is all about taking things apart and making your own creations too. Yet I can’t find a way to, for example, say that “port A is the release motor on my catapult” if I disassembled the Liebherr and made a steampunk trebuchet, for example. I can rebuild my LEGO bricks, but not the app, I guess.

Great, needs work

I got the top gear rally car as a gift and had a super smooth time connecting with the app. I found the calibration super useful and the manual transmission fun to use. I did have a little problem with the gyro control though, it seemed like the sensitivity was very iffy sometimes I would have to turn my phone all the way to portait mode for a turn and other times it felt like a small bump would make the car turn a lot.

One last thing is that control+ should support custom control setups because making things into other things is what Legos all about. I think the mindstorms app is a good example of a good custom control system. I made a tank with my rally car but had to use a third party app to control it.

Thanks for your time. I hope you consider my idea.

Very cool app

App has worked great for me with the Liebherr excavator. One thing I would like to see is the ability to edit your saved movements so you don’t have to start from scratch if you want to make slight changes. This is the only reason why I don’t give it 5 stars.
