Do drum shaped robots roll over ok after being flipped?

I asked this about roll over bars, but have since discovered Morg, Mega Morg etc and wondered if the shape worked in the end? Or are you better being invertable / powered self righter etc?

[typhoon_driver]

passive attempts at self righting are rarely if ever successful unless you count something like the full bodied spinners in the US with their bent poles sticking up. Always use a powered option if you can.

Not always, no. It sometimes runs out of energy. Or hits a wall. Or some one does something stupid like let it get flipped onto the join between two curved panels and the flex takes all the energy.

By comparison, The Morgue could self right entirely with very little energy due to that squat shape. If it had an embedded axe, it could have won that heat.

Ok. I started building myself a heavy today! I'm going to enclose the wheels so won't be invertible, and because I wasn't including a flipper thought I'd ask about passive self righting lol. I will need to sort something else out lol.

I would say they do work at least some of the time!!

The best for this was Mighty Mouse. I could go off praising this little robot as it was one of my all time favourites, but I will resist the temptation.
The trick I think was to keep the robot narrow and the centre of gravity very low, also I think the roll-over bar was oval, and in the last few years held on by springs.
I would love to make something like MM myself.

Yeah Mighty Mouse and MeggaMouse are some of my favourite robots. I have wheelchair wheels so don't want them getting punctured! I'd thought about building a barrel shaped body to roll over back onto wheels if it got flung but the general consensus is don't bother lol. Which means I need to be invertible (wheels go pop) or have a way of rolling over/have lifter type weapon that can also roll you back over. So its looking like a fairly complicated first heavy lol.

Having said that I have used lin-ac's in the past so I'm not that scared of it. I wondered if something like Iron-Awe 5 / Megga Mouse would work with lecky actuators instead of CO2? If you found the mother of all actuators and put them far enough back up the arm. It's not going to fling stuff like CO2 but I'm really curious how much kick you could get.

I'd wondered about having something daft like three big actuators power a flipper.
