Here's a very simple way to use some PVC pipe sections and a couple of 2-liter pop bottles to make a beam scale to weight your robot. As the instructions state:
a) This is not an EXACT measurement
b) Be careful in attaching the beam scale to the ceiling beams of your robot lab
c) There's no need to lift the robot off the floor more than an inch or two.
Basically, a 2-liter pop bottle full of water weighs 2 kilograms. If you balance two pop bottles equally on a stick, you can then measure the distance and extend that distance out as a ratio of weights.
As an example. a 50Kg robot (110.2Lb)on one end of the beam, 2" from the centerline is equal to the 2Kg pop bottle on the other end of the beam when its distances is 25" from the centerline.
