I haven’t used it, but I thank you for pointing it out. (For others, the link is http://www.vexrobotics.com/.)

I hate to say it, but this looks like it rather blows the socks off of standard LEGO robotics. The starter kit is $300, which is a 50% pricier, but comes with some really cool features out of the box that are very difficult or impossible to add to Mindstorms at all. For example, a radio transmitter and receiver, that lets you interact with your robot by remote control (in addition to its autonomous control via the programmable microcontroller).

Additional parts are nicely available and well-priced, too -- for example, $20 for a servo kit, $50 for a radio crystal set that enables four different frequencies, $13 for an extra set of gears (duplicating all the gears in the starter kit, plus two more), and $50 for a battery charger that can charge robot and transmitter batteries at the same time.

The major drawback, of course, is that the dang thing isn’t based on LEGO, so it’s going to be a PITA to build and comparatively limited in the physical structures you can make. Looks surprisingly fun anyway, though.

I found a review of the VEX system that may be useful: http://abcnews.go.com/Technology/ZDM/story?id=817378

I haven’t been able to find much detail about the microcontroller, except that it contains “dozens of ports for sensor plugs and jumpers.” It’s not clear exactly what that means, though. Nor can I find any information about how it is programmed -- apparently it comes with a preset program you can tweak in small ways via jumpers, but they also claim it’s “programmable.”

I hope this gives some inspiration to both the engineers and the marketing guys at LEGO... I feel like LEGO robotics is falling behind, and has some catching up to do.

Best,
- Joe

Hi Joe, Their website seemingly offers a lot of other gadgets. However, I have serious doubt about the programming platform though. Or, perhaps I have not found much about the programming language which can interface with it. ---...--- -------- (...) (19 years ago, 21-Jun-05, to lugnet.robotics.rcx, lugnet.robotics.edu)

(...) I don't think so. (...) Sure, but it seems of not much value regarding programming. The informations on the vex site are sparse and not easy to decipher, but I think you will have to: - pay aditional $99 for somethink called easyC, that is (...)
