Vex High Strength Drive Shafts

Hi! Does anyone know if the high strength drive shafts would help with getting up the See-saw? My team is debating making that change. please let me know what you think. Using basic vex knowledge, it will help, but I do not have experience with these specifically. thank you!

Your ability to get onto the platform can be determined by a number of things, such as traction, or the inability to let your robot tip at a point to be able to climb it.

However, I don’t think that using high strength shafts will help tremendously, but, again, this depends on what is limiting your robot. High strength shaft help the robot with applications that put a lot of pressure on the powered mechanism, but the platform shouldn’t be putting that much pressure onto the wheels to the point where you would need the shafts. However, if you feel like you need to add them to fix it, then go ahead.

My advice would be to slow down the drive via gearing or changing the motor speeds in the code. This would give it more torque, and therefore traction. If you change it in the programming, you might be able to add a button to toggle these drive speeds so that you can still keep it going fast while it’s on the field.


Ok. Thank you! I will try to add it in the code, otherwise I will try to get it geared differently. thank you.

Changing the drive speed in the code will not give you more torque. It will only decrease your output power.


Is there a way to increase the speed of 200rpm motors through coding and not through gearing?

Not past 200rpm

No, thats not how motors work.

However, you can decrease the speed through coding


That’s what I assumed, but I remember that once my programmer made my robot faster and it had direct drive (with chains), and it was so fast that I had to ask him to turn the speed back down.

High strength shafts are just stronger than regular drive shafts. They don’t really have any more advantages except for being extremely strong.


You can use voltage control which occasionally can spin slightly faster than 200 rpm (around 215 or so), but other other than that, not really, no.

The only way you’re going to increase the angular velocity without changing the gearing is by increasing the voltage, and doing so would require bypassing a lot of things that aren’t meant to be bypassed (i.e firmware and the rules of the competition).

Now, if you want to increase the linear speed without changing the gearing, that’s a different question entirely. You can do so by simply switching out for larger wheels.
