Entrylevel Robotics idea?

Several of us are starting a "microcontroller" club in our community, and one of the guys hit on an idea of
using erectorsets combined with servos as an inexpensive entry point into robotics. I was struck with the
simplicity of this idea, and was curious if others here have employed existing items like this into their
robotics hobby?

    Lego blocks are another cheap intro approach that I have seen many people use. I'm not talking about the official Lego robot kits but servos with Lego wheel connectors glued to them, Lego plates glued to bread or perf boards, Legos glued to sensors, and etc.

    You can get some ideas by looking at Botball sites on the web. The official Botball controller has been recycled Gameboy controllers which is kind of cool since you get audio and video built right in. You can get some of the used Botball controllers fairly cheap on ebay from time to time. Unfortunately, you need to know a version of C to program those controllers but I don't see why you couldn't construct something similar with a BOE.

    Of course, there's always those old remote controlled cars and trucks that you can recycle into robots as well by wiring on a BOE.

    Hello Oldbitcollector, I have built a LEGO tracked bot using modified servos and drive train, You can see it here robosapienv2-4mem8.page.tl/on my website. It uses a BS2P and twin Ping sensors. The tracks are genuine LEGO tracks and works very well. The idea is quite a good one as you can convert most building sets into some form or another for robots.
    My site was down 5.0pm NZ time, so if you cannot access try later.

    Hi Oldbitcollector, I think the idea is very good when doing prototypes and testing concepts. I use an old Gilbert erectorset. Just keep in mind that erectorset are limited on their selection of parts and gears. Lego on the other hand have a wonderful selection and many specialized parts can be found all of wich are reusable on your next project.
    Have fun, cheers

    Take a look at linxmotion's website. They have a product called the "Servo Erector Set" It may be useful to you.

    Sumobots seem to be one of the best communial activities.

    Everyone has a different idea of how to best build and best code a robot. Of course, you might exclude premade sumos from all but 'unlimited class' competition as someone can easily buy a winner rather than learn anything.

    Alternatively, premades would have to be matched to eachother. IN that way, the software would really demonstrate the competators skill.

    Other activities - such as line following and maze solving are of great interest. Mazes can take a lot of work to build.

    Nice link to TOm's bipedal robot Whit, I have 1,000's $'s worth of Technics and these are great for experimenting in robotics, I just need to learn Pbasic quicker. I have about 7 or 8 robots waiting to be programmed. [noparse][[/noparse]D**n]

    StampNut2,

    No problem! Can't wait to see those 7 or 8. All I've seen from you so far is pretty cool - not to mention your workspace!

    StampNut2, that's one of the most impressive robots I've ever seen!
    How are you controlling the base?
