    Basically our objective is to get the stampbug to do 'gymnastics'.
    We will be awarded marks for musical interpretation, entertainment factor, technical content, visual/audio/special effects, mechanical aids and floor coverage.

    I have attached an image of the stampbug to the post, also here is a link a previous team had done

    We have a £50 budget, and we kind of need a 360 degree servo ( I can't give too many details away as to what we are planning as we are in competition with other groups) and these could eat at our budget so we were thinking of trying to modify a 180 servo to rotate 360 degrees, has anyone experience doing this, if so how did you do it?

    Also does anyone have any suggestions on mounting the servo, as if we are to have a 360 servo, we could run run into problems with wiring. We were thinking of just having the servo rotate 180 degrees then back 180 degrees if we can't find a way over this problem.

    Many Thanks.

    Servos are only 180 degrees, perhaps external 2:1 gears would offer you what you need.

    There are some that rotate 360 degrees, but they are more expensive and may need to modify them to make them continually rotate. Thanks for your reply though

    Do you have a part number or site link?
    A modified servo usually has the limit pin & pot removed. It will act more like a speed controllable motor (see the Parallax BOEBOT as it uses them)
