Vlad Micro is a relatively easy to build R/C combat robot based on the original 200+ lb Battlebot "Vlad the Impaler"
I'm calling these all-plastic 150g bots 'table toppers' with the idea they should be simple, cheap, and safe enough to operate without a costly enclosed arena. If it turns out other people want to make these (which would be terrific) a set of rules is certainly a possibility, but for now, safe and small is good enough for me.
The Top was printed with supports ON, and pretty much requires them. None of the other parts should require supports.
This robot was designed to be both simple to build and safe(ish) to operate. To make this machine run, you will need the following:
2x N20 sized micro gear motors. I use 30:1 gear ratio. (Probably out of stock but here: https://hobbyking.com/en_us/brushed-motor-15mm-6v-20000kv-w-30-1-ratio-gearbox.html )
1x mini servo. Any standard mini-servo will work, though metal gears and higher torque are plusses
2x 25mm Lego tires. You can buy them in bulk off Ebay (like I did) or just raid your Lego collection. You're on Thingaverse, so odds are good you have a Lego collection.
Ant electronics. 2x ESC (Fingertech Micro ESC x2, for example) and 1x RX, as small as you can find.
1x 2S (two cell) 7.4v battery. As small as you can find. 220mah is a tight fit, but works.
3x tiny Wood screws to mount the top to the base.
2x screws (or wire) to mount the servo
Small zip ties to hold the motors in place.
Some steel rod/wire to mount the lifter, back wheels, and make a linkage from the servo horn to the lifter. Must be able to fit through 1mm holes and be a rigid as possible. (I just bought mine from the local hardware store.)
