hmm toast omnom, -

anyway but would still b more helpfull to see a design or something, as you'll most likley want it different thicknesses throughout the robot and all that

[AbundantToast]

Mhmm, Im still not sure, Im going to have a 3 or 4mm aluminium bassplate but would 20mm hdpe be too thick and heavy for a four drill motor drive, hazard type bot?

[AbundantToast]

Also I know this is off topic but what type of motor could I use to power the lawnmower blade or bar?

[calumco]

i would have thought 15mm hdpe would do, but again it depends on your design and how you'd mount your lawnmower blade and everything,

and just go for a motor called a speed 900 because its simpler that going brushless and since its your first robot you'll find it easier to get up and running although your still gonna find building a spinner difficult at first
