Robot SMASH!! Series 2: Recharged!

Why exactly is horsepower so important anyways?

[majinb]

a frequently asked question Joey, and even though the people saying hp doesnt matter once youve lifted your opponents wheels off the ground are completely right, I theresay the connection between hp and acceleration is highly important and sometimes deciding. Also the added hp means youll hit youre oppenent harder.

Okay, just wondering

No you dont.

force = mass * acceleration. Whether you achieve it with a lem or a bosch, 20mph * 100kg is the same force.

Torque and speed are a much more important factor than horsepower.

I have to disagree Leo, you state force=mass*acceleration, which is true, then you use the example 20mph * 100kg, multiplying a SPEED with a mass, instead of multiplying an ACCELERATION with a mass like you should, and I do believe more horsepower DOES equal more acceleration

No it doesnt. you accelerate to a speed. and wether you reach that speed on a Lem or a Bosch, its impact will be the same. The Horsepower however can be used to create more speed (lower the reduction), or to shorten the acceleration ramp, but the outcome will be exactly the same if both robots have the same speed and mass no matter how much horsepower you got.

the horsepower might give you more through force if you get me. i.e. if a 100kg robot hits another 100kg robot and the drive is say bosch on 24v lets say they come to a halt but if the drive on 1 robot was say lems on 36v then the force might carry the robot through and not come to a halt. that might be what martijn means which i mabee agree. but then if they are the same then leo is right.

Fact remains Leo, that in the post I initially replied to, you stated F=M*a, and you went on to give an example that contained M*s.

Momentum (Dutch: impuls ) = M*s, so yes, theres no difference in LEMS and Bosches there. As is in kinetic energy, which also contains mass and speed.

[leorcc]

Where Lems and Mags and Perms and so on win is on torque. If you manage to get the horspower to the ground, on the same speed you will win a pushing match. You can accelerate faster than a Bosch would be able to so in a small confined space like an arena that will help (box rushing comes to mind).

But extra horsepower will not make you hit your opponent harder, which was what you claimed.

[majinb]

Lol, yes, very true leo, I was just confused by you initially stating force = mass * acceleration as an argument, where its about momentum. In the end you are right
