THE FIGHTING MILKMEN

SKIMPROPOSAL

The Proposal

SKIM MILK• 3lbs. – Beetle Weight Class

• robot frame – 6in. X 5in.

• designed to allow other bots to destroy themselves by using their weapons against them

• no active weapon – lack of beetle experience

• continuing design and weight considerations…

Carbon Fiber top & bottom plate

Wedge design for shoving

Steel Teeth for grasping and safe energy absorption

High speed motors for quick acceleration & speed

Shore 30A hardness wheels for

maximum power transfer to metal

~$350.07 ~1.47lbs

We have a lot of head room considering the current weight & cost but don’t forget, the weight

& cost excludes batteries, hardware, motor mounts, any internal structure, etc.

Just like Vatamin D (AnkleBiter), the robot, at this point, is capable of becoming whatever we want it to be because of its simplistic design.
