Hi All!
I’m wondering how building an EH3-R from the kit compares with building roughly the same thing using the Erector set both with regards to cost and learning curve.
I’m pretty much a Noob when it come to robotics and especially programming,(built the boe-bot and some silly beam-bots), would there be any reason to to choose one over the other based on programming?
It seems that if the two strategies were roughly similar in cost and complexity the erector set would win, in that it is reconfigurable, but perhaps given my noob status I’d find the kit more accessable.
Another question re the erector set; does there exist a database of collections of parts required or recommended for specific projects?
Personally, I’m a fan of aluminum.
Lexan just bends too much for my taste.
(Although that’s not really a bad thing).
The programming is the same, no matter what configuration you use (provided that you use the same amount of servos in the same general area).
And, if you do chose to change the amount of servos, or the position of them, it’s not hard at all to adjust sample code to suit it.
Soon, Jim will be coming out with a tutorial for the erector version, so building it should not be a problem.
If you just can’t wait for that (and, I don’t blame you ^.^), then get together a list of parts that you think you’ll need and post it here.
We’ll tell you if you’re forgetting something.
You can get an idea of what your going to need by staring at the prototype picture on the website.
You can also look at the tutorials for building legs and whatnot on the site (click on Products, Servo Erector Set, and at the bottom right corner there’s a “What Can I Build?” link).
Don’t worry about programming; you’ll sail through it if you buy the Visual Sequencer.
It can export Basic code that takes care of servo timing and position.
With that out of the way, the rest is very simple.
Hi Nick,
Thanks for the info! Especially the part about “don’t worry” about the programming, I’ve been building things all my life, so thats the bit that intimidates me.
I costed out the EH3-R with the erector set using just the metal hub in the middle (no lexan bits), it came out a bit more expensive (roughly 20 %)but it seems worth it to have the future possibility of reorganizing the parts.
Anyways, thanks for both your reply and your encouragement.
Just a heads up. We are adding a new version of the EH3-R that uses the BotBoard SSC-32 for PS2 controller RC. We just finished the tutorials, check what’s new later today. This relates directly to the aluminum one too.
If the visual sequencer can export code thatn how do you get that to the BS2 and then use it to program an autonomous behavior? still very fuzzy o theis issue.
It’s exported as a .bs2 file.
You simply open that file with your basic stamp programmer, and upload the program onto the microcontroller with that application.
