[JB987]

If you are at a school you most likely have a doctor's scale in a nurses office or in the phys. ed. dept. for wrestling, etc...you can actually weigh the front of your robot (with wheels resting on boards or stock metal laid across the base plate you stand on) while the rear wheels rest on a stack of stock/ boards on the floor and level with the front rests...record the weight minus the boards/stock that was on the scale's base plate and then turn the bot around carefully and weigh as you first did (minus the support stock/boards weight of course)...just add the two weights up and you are set! We have always been within a half pound of the expensive scale used at the competitions...this is of course a way to tell total weight but it is better to weigh and record components before you assemble and again a typical scale will get you decent weight information...
