Yes mate i got a pic a few days ago next to a cup for scale, also thanks to gary for showing me a website what works out the KE energy for spinning disc and its coming out at 4.4KJ what is even very good for a featherweight so this should be fun! also a video of the first spin up on a flat lipo and half throttle
Half throttle AND flat lipo?!! :shock:
I'm just going to bin my kilobot chassis now and be done with it
Although there may be a ray of hope that could be revealed by this question: Kenny, are you putting a magnet in it?
nope i wanna see it fly!
Yep, fail indeedOriginally Posted by mr_turbulence
That what you get for just picking up some tools and going to work
Not quite on the 3kg mark but when i weighed it earlier today without the lifter it was at around 1kg and the servos weight 300g on their own witout the lifting arm and scoop. It's built from some 6 & 10mm polycarb I had kicking around and some 12mm nylon 6 so all a bit on the big side for this weight class especially seeing as in most places it's 18mm thick. I have a bunch of 1mm & 3mm ti kicking around but didn't really want to use that for the 'development' stage so it'll come down a lot if I want.
I'm actually more inclined to beef it up and use it for the battleratz and start again with a single servo and heavier metal armour. Will stick with the same basic shape just go for everything a bit smaller. Reckon with 180 around, armour is going to be the big thing. That really is an impressive machine!!
kenny thats rate good, but ya no its gonna fly off as soon as it hits something :P
Woah, surely it's got to be clocking surplus of 10,000rpm for that much stored energy?
17000rpm
Lets imagine that hit the wall and the robot inherited most of the energy, it'd fly off at a (pointlessly theoretical) 270km/h.. here's gambling something breaks instead =p
Might want to tacho it to see what it actually goes up to, you won't actually get to your no-load rpm you know :P Ive got a laser tacho knocking about somewhere, you just put a sticker on the disc or whatever and bounce the beam off it - be happy to bring it to the first kilobot event
Here's my attempt- decided to go for something a little bit different this time.
It is a 2 wheel drive robot with an interchangeable weapon bay at the front- i've got 6 different setups planned- the first one has been built and fitted- a drum spinner
Heres the stats
Name- not sure yet
Weight: 1.275kg at the moment- will be around 1.35kg with the second battery fitted
Length: 20cm
Width: 21cm
Height- 5cm (with no weapon)
Drive- 2x MFA 30:1
Speedo- Sabretooth 10A
Battery: 2x 1000mAh 2 cell LiPo
Weapon Setup 1: 200g spinning drum with 6 teeth powered by a large brushed motor on 1:1 ratio- Blue speedo to control it
Armour- 5mm HDPE
More weapons coming soon- i'm hoping to make an upgraded version of the drum with a better made drum and a brushless setup to give it a bit more power- this one seems to work reasonably well to start off with.
I'll get a video of it running online tomorrow but heres a photo of it as it is right now
