Looking good!
Will be interesting to see how it handles =)

Yeah beater is 500g. With the new design being within the weight limit looks to be easier. The robot is farking massive though.

And is that still at 500g too? That sounds more than a bit lethal! Looking forward to seeing it in action!

Cheers guys.

I geared it for around 4000rpm last time. Felt a bit lacklustre so I'll up it a bit this time.

I can see this being a pretty brutal machine once it's finished! How fast does that beater spin normally?

Tormenta 1 was a chopping board powered by £10 motors too.

Looks great man, as I've expressed. Those hex pulleys came out sweet. This'll be a cool robot.

Ok, Just sticking some pictures of my beetlweight builds up here.



Old, first version of the robot for anyone who doesn't know. Looked pretty cool but had some really, really bad flaws.
I've learned (hopefully) from this and have changed the design to improve the robot.



Here is the new version before I worked on it today. Frame is 10mm chopping board (I know, a bad idea but I can't really afford different yet) the motors are 1000rpm ones from ebay. The pulleys are custom made by Ellis. The "belts" in the picture are hair bands because I didn't have anything else to hand.


Here is a untouched pulley next to the one I milled a hex onto. Reason for doing this is so it can fit onto banebots wheels because the adaptors are too expensive for me. It also has a grubscrew in it to hold it onto the D shaft of the motors.



Did all four and made up some belts. The stuff is basically O ring material but I cut it to length and then joined it with a soldering iron. Works well!






That's where I'm at so far. Need to get the armour made and mount and wire in the electrics.
Should be interesting to see when it's finished and see if it performs ok for a chopping board robot powered by £10 motors

Cheers. Harry
