Team 3038 Drive Train

[tomy]

This is our second year and we create a drive train that can pull and push a 120lbs man. If you like post comments, I will try to get more videos of it driving.

Here is one

Here is the second

any comments or questions just post here

Pretty cool.

A better test of pushing power though is setting up a scale against a wall, placing your robot in front of it and then pushing forward until the wheels slip or the motors stall. That will give you a quantifiable thrust.

What you showed in your video is that your robots thrust (weight x CoF) is more than the mans traction (weight x CoF) while on his butt

... But it is cool to see robots pulling people

Most robots will proboly weight 150 ish pounds and will be pushing back on you with as much or more force... Just saying.

Back in 2003 (The challenge with totes) when the CIM were just starting out we had a robot that pulled a HD Truck with a larger trailer (Only 2 CIMS allowed). So these motors can pull quite a bit if geared right and there is enought traction.

But they also had those 2 drill motors which I believe were more powerful than the CIMs.

Yes those drill motors were pretty insane. Paired up with a CIM they easily pushed around 300lbs (weight of person + CoF) + when properly geared.

...maximum weight limit 120?
I'm not sure where you're getting 150.

Anyways, pretty cool chassis; it's awesome to see it get that much strength, although as someone said, a wall-scale test would do best.

120 for the robot + 20 lb (max) bumpers + 15 lb battery

you still have to admit that we have a good drive train.
