Team Snakepit - New Build

[Viper]

Work has now started on the latest addition to the Snakepit. We are now working on a spinner as the next project.

The design should make it invertable.
Chassis and arms are going to be made from 1.5mm Carbon Fibre.
Motors will be HP 50:1 Micro Gear motors.
Outrunner motor from Robot Birds (which they don't appear to sell anymore!)
Battery is a 240mAh Hyperion LiPo.
Speed Controller will be an option D from Pete most likely.
What ever weight I've got left at this point will then determine the final blade design but will be looking to get something made up in titanium hopefully.
Original mock up looked like this


More photos to come shortly.

Oh and I've now had a request for a tracked robot!!

Looks very nice.
Should be effective.
How are you going to make the blade?

[earthwormjim]

Just had a thought... While making Boreworm,I found that the wheel placement was critical.The further forward,and wider apart you can make the wheels,the more stable it will be with the disk spinning.If you can,run it first in a prototype adjustable chassis,just to adjust the spacing.It helped alot.

That looks huge, does it fit in the cube?

[Viper]

Going to see what weight I've got to play with before I get the blade made. Going to have to find someone to machine one (or two) for me. Any suggestions, I'll have to have a look around at the local engineering companies.
Got he chassis together now.



It does fit in the cube, just, had to shorten the arm a bit when I changed from circular to the pointed version. Goes in diagonally across the cube.

Just picked up some 0.5m and 1mm Titanium off of Ebay which I'm going to use to strengthen some areas and stop the front spreading.

Here's the cube.

Looks like I've got about 30g for blade.

Got it all connected up and everything worked, which was a surprise , might need a bit of tidying up though

Didn't know if the spinner motor would work with the 3rd channel on the Annsman controller but that was the easy bit, getting Pete's controller connected in the right order was more of a puzzle, you wouldn't think there was so many combinations with three leads and 2 slots!

Just need to sort the weapon out now.

That's epic work for a debut robot, big congratulations from me! One question, why do you have the screw terminal blocks to connect the brushless motor up? Why not just solder? Takes up less room and is lighter.
It's looking brilliant though!

Hi Dave

I was using the terminal blocks just to prove the system, they'll disappear along with most of the wiring when I tidy it up.
