    Re: Meet Hi No Hikari

    I'm going to have to check with Dave, but I believe the segment above where the arm servos are would count as a head if I tape some googly eyes to the front of it. I'm not really sure what the classification of a head is, but given that the brains (the arbotix) are in there, what more could anyone ask for.

    Some people build for function prior to aesthetics.

    Re: Meet Hi No Hikari

    So the brown truck paid a visit today, and Hi No Hikari got a set of arms. Disaster though because Hikari is about 250 grams overweight. This makes Hikari a middle weight and puts it up against bots like Giger...

    The cool part is I get to make a second Hikari. The current plan is to upgrade the hips and ankles using AX-18Fs, Cut some out of the arm, and top portion, and feet in the hopes of loosing the weight.

    Here are some picks.



    I'll try to get some motions done tomorrow and some video this weekend.

    I can tell you from experience, 250g of weight is a LOT to shed via cutouts. You'd need to drop 3 servos as well, at least. What are you using for a battery? Milspec lipo might be in your future.

    Re: Meet Hi No Hikari

    Switching to a mill spec lipo, thinner metal for the feet, cutting chunks out of the body, and getting aluminum screws for the ankle and leg brackets...Maybe I'll tie some baloons to the top if all else fails. :-) Actually if all else fails I'll be switching all of the servos for RX-24Fs and 28s in the ankles and hips...but that is more of a long term plan...which really makes the whole thing mute...SO instead maybe I'll just let Hikari 01 get her butt kicked and hope that Hikari 02, the 24F version does a bit better.

    Tybs -- you don't build your bots out of 1/8 thick scrap metal though...

    Unfortunately no...with the exception of the feet this bot ia all aircraft grade aluminum .004 thick I think. I'm coming to the conclusion that this bot is just going to be an overweight looser.

    Re: Meet Hi No Hikari

    I heard drilling holes in your battery is the best way to lose weight!

    Honestly though, you won't lose much drilling holes in your brackets, aluminum is only 2.7g / cm^3 , you can do a quick calculation to see how much you'll lose per hole. Its a good backup if you are really close to the limit, but at 250g you will obviously need to take another approach. I tend to see drilling holes as something you do after your bot is done and you are only slightly over.
