Weight Issues!

Hi Matt, just reading through the specs of the V4 hexapod, and you give the weight as aprox 1.8kg including batteries. Your hex seems a similar size to mine, but im using considerably thinner aluminium, and mine still weighs in at 2kg with no on board power! I have completed a re-design of all the parts and managed to drop down to 1.5kg, but this is using a very minimalist design! Just wondering if you could give me a rough breakdown of any component weights, or any advice to see where I should look to try cut back. Cheers, Alex.

Re: Weight Issues!

Hi Alex,

The majority of the weight is in the servos. For the V4b design, I use 12 x Futaba 9206 servos and 6 x Futaba 3002 servos. The 3002 servos are much smaller than the standard size servo, so I am probably saving weight with them. Also, the first two gears in a 9206 servo are plastic.

The battery I used would have been a Twicell NiMh 4.8V 2700mAh pack.

Matt.

Re: Weight Issues!

I don't know mine but I guess will be around 3.5KG without battery. I have onboard mini-PC and laptop harddisc, so even 9KG servo won't have enough power to stand the hexapod. I plan to lift hexapod in the air for test program, walking in the air :-)
