This is how we weigh our bot.
1- 116 lb hardworking freshman
1- piece of spare portable-classroom ramp handrail
1- long piece of 2x4
1- tape measure
- Place the handrail under the 2x4 exactly at the middle mark.
- Place the robot over one end of the 2x4.
- Place the freshman onto the other end of the 2x4.
IF: The freshman’s end of the 2x4 is touching the ground, the bot is <116lbs.
IF: The freshman’s end of the 2x4 is off the ground, the bot is >116lbs.
Like I said-- my favorite/the most versatile tool is the freshman.
(Seriously, though, this is how we weighed our bot- for the first time- just before shipping.)
