I recently made a lego battlebot. It can use a spinning hammer to smash and bash lego apart. It's hammer is a 1-16 beam with some weight bricks on each side. The hammer is powered by 2 power functions xl motors, and an adder mechanism, made by searme. for my newer bots, I shold be using pf motors as the movers for the wheels, not spybots....

  • you should connect the hammer direct to the battery so its constintly rotating

  • The reason why i didn't was because sometimes, you need to hit things at different directions, like pull off brick, instead of push them down. Its kinda hard to explain, but whatever.

  • 6:44 oh dear haha that happens alot in my battlebots too!!

    I like the idea of using a differential - when I let others drive my spinners I'm relying on them not turning the weapon on when it can't move... which makes me paranoid!

  • Firstly, the reason why the 8t gear some loose is the differential skipped twice before in this video (which is now fixed!)

    secondly, the reason why I used a differential is because it makes an adder, which combines the torque and the speed of the motors.

  • "which combines the torque and the speed of the motors"

    I had no idea differentials did that! Thanks for the info.

  • The differentials only work tis way when they are in that configuration. Also, Im not sure if the mechanism exactly doubles the spped and torque, but i know it is far more effective than just puttung two motors to one axel...

see all
