New Featherweights

do you guys think that those drill motors will stand up to being thrown around by flippers

Yeah they should cope comfortably. Something to bear in mind is that when you get flipped, the chances of your robot landing straight onto its wheels is slim. You'll usually find that an edge or corner of your robot chassis hits the floor first, taking most of the energy out of the impact. Then once it has bounced around a little and gone onto its wheels, there is nowhere near as much force going through the drives than if the robot had landed straight onto its wheels.

I use cheap drill motors in all my robots and have been flipped several times but have never suffered damage to the drill motors as a result. This isn't to say it will never happen, but it's not a common occurrence.

You can do a full speed control from just servos. It's similar to the way I'm planning to make Stack Error 3's flipper massively powerful except you use a much bigger H bridge, don't hook up the servo's motor (you only need the board) and you do a 360 mod to the servo.

I'm not sure about safety but it will certainly work

Edit: I'm thinking of changing the hammer weapon on my featherweight to a much simpler pusher that can still strafe like the hammerbot however is invertible, can spin very quickly and should be much stronger due to my plan to make a steel outside shell with the bits where the wheels are from thinner steel and some plastic to add thickness to the motor mounts and the base and lid.

I might call it 'Son of a Brick' and paint it red or paint it yellow and call it 'Black Box Fight Recorder'. [/url]

After much thought and discussion with my Dad, i have decided that i will stick to ants, as feathers are a bit out of my price and time range. I might be able to do one when i have more time and experience, but antweights are fine for me.

So to make up for it, i have decided to announce the creation of my new ant- FrANTic!

It certainly isn't lacking in speed and isn't phased by grass (although I don't know how the latter will help in the grand scheme of things).

Are those rechargable AA batteries your using by the way?

aa sized cells, yes
this is why you should spend more than ?43 on a feather
