Re: Scioly Assassination 56: Mission Impossible

Just wondering, have any of you guys ever even taken a math class ? A non-zero number divided by zero is an expression that evaluates to no value, not a catastrophe or contradiction. On computers, the IEEE-754 standard has well-defined rules for what happens with a division by zero (including divisi...

Re: Sumo Bots B/C [Trial]

As for electronic braking: yes, do it. All decent commercial motor controllers can do electronic braking by "shorting the motor terminals." This forms closed loops in the motor's windings (in the rotor for an plain-jane brushed DC motor), which resists change of magnetic flux (e.g. the rot...

Re: Sumo Bots B/C [Trial]

I have an idea: sumo wrestlers should have both of their arms amputated. It's so unfair that they can use those limbs to get leverage over other wrestlers. This way, head-butting each other from a standstill is more important than maneuvering and devising strategies around frame strengths and weakne...

Re: Sumo Bots B/C [Trial]

I had 550-size motors, where the "-size" is a quasi-standard for a motor whose can is about 55mm long. They are easy to find, but finding a good gearhead or gearbox for them will be hard. That's why I think power tools are a much better source of powerful motors with gearboxes. Cordless dr...

Re: Sumo Bots B/C [Trial]

I don't understand why you'd ever build light. There's a maximum mass for a reason. I designed under the assumption that everyone else would build to at least the pushing force given µ = 1.0 and given maximum mass, and at least about 10 ft/s of maximum speed (yes, per second). The only reason you wo...

Jeez DH, that there looks like a list of everything I did wrong or half-assed in the past half-year or so. ;)

How about this? You don't put a Raptor Jesus picture on your wiki userpage. If your problem starts with, "I want to...," you probably shouldn't ask somebody else to solve it.

Re: Sumo Bots B/C [Trial]

Congratulations. There's a new 4 channel radio system from GWS compatible with the rules. It's 2.4GHz (meaning you don't need crystals) and is only $42 for the transmitter/receiver. Supposedly binds quickly, but I don't have specs on interference resilience. http://www.robotmarketplace.com/products/...

Re: Sumo Bots B/C [Trial]

Each channel of control is encoded into one signal and sent over the radio link to the receiver, where it's decoded and broken up into separate PWM signal channels which can run servos, motor controllers, etc. The "channel" of the radio link is another term entirely. The radio spectrum is ...

Re: Sumo Bots B/C [Trial]

Well, you're also pointing out the cost of the event while commenting on the discontinuation of a Vex product. There's more than one axis of ironic beauty to that statement.

Re: Season 2011 - Site suggestions

No, that's just asking for abuse. Think about it.

Besides, the posts that use such a box might as well not be sarcastic in the first place if it needs to be made so obvious. Sarsly, it's sarcasm. Learn to do it.
