remembering a specific battlebot?

Juan Pablo — Tue, 27 Jul 2010 08:23:15 +0000

I’m looking to see if anyone remembers a robot that was in either Battlebots or a show like it. It was round, low to the ground, and spun like mad. if i remember correctly, it was colored like the american flag. it worked kind of like ziggo.

I have been trying to find it too! my friend says she met the guy who built it??

if i find it i will let you know?

was the guy a teenager?

Antweight Battlebot chassis

Juan Pablo — Tue, 20 Jul 2010 10:36:02 +0000

The is the spinning chassis of an antweight (1lb or less) battlebot that I designed using Solidworks. The outer spinning portion and the top and bottom of the chassis were water-jetted from 6061-T6 aluminum pieces. I used a lathe to turn down a 1/4″ steel shaft to the correct length and add grooves for snap rings (to hold the bearings in place). The aluminum “pillow block” that holds the bearings in the center was also turned down using a lathe. I’m using 2 sealed-cartridge, ABEC-5 bearings to create smooth motion.

For an antweight battlebot, I’m wondering about the speed controller?

Juan Pablo — Sat, 17 Jul 2010 12:35:43 +0000

I’m planning on using a brushless motor for the weapon, and possibly two brushed motors for the wheels, so do I need more than one speed controller? Do I need a speed controller for brushed motors? Can one speed controller be used for multiple motors?
If you have any recommendations in general that would be helpful. Thanks.

Brushless DC motors don’t self commutate and so need electronics to "emulate" the brushes. Controllers for them take the position of the motor, combine it with a desired speed and use that to alter the flow of current in the wires feeding power to the motor.

Brushed motors don’t need to emulate the brushes, and so a very simple on/off switch will function as a very basic speed controller for a brushed motor. ie off=0 rpm. On=max rpm. Switching such a motor on/off fast, is called PWM, and allows the speed of a brushed motor to be altered between on and full, using only a single transistor. If you want option of reverse you’ll need some more electronic switches (transistors) to form a H-bridge.

I’d probably use a pic uC to generate control signals for the switches. Transistors convert those low power signals into power feeds for the motors. This could all be fit on single PCB and would constitute a motor control board. Best to have some decent heat sinks on the transistors! Once the circuit is running/tested, it might be worthwhile potting the board up (make sure the heat can still escape from the transistors) If the resulting box (filled with potting compound) is strong enough you could perhaps use the box as a structural member, in much the same way as F1 cars use the engine to connect the rear suspension to the rest of the car.

You need some kind of controller/switch for each motor you want independant control of.

About how much money does it cost to build a battlebot/combatrobot?

Juan Pablo — Wed, 07 Jul 2010 00:46:05 +0000

I want to build one and don’t know how much money it costs. If you guys could tell me about how much it costed to build yours, if you did, and post a pic if possible.

If you are talking about the ones shown on TV competitions, depending on how good/lucky you are at scrounging and how many tools you already own and what you have to pay for, anything from a couple of hundred to a couple of thousand. Almost everyone has to buy the radio stuff and batteries or have bought it in the past and kept it, but buying the motors can be costly while handy scrounging can drop the cost. The cost of building the frames, shells, "armor" and "weapons" is where handymen do it with their own time instead of their own money.

UNH Battlebot Destroys Microwave

Juan Pablo — Tue, 06 Jul 2010 13:22:07 +0000

The robots name is Smash & Wrecker.

Thanks to the University of New Hampshire Electrical and Computer Engineering Department and all of our sponsors especially Black & Decker for their contributions, without them none of this could have been possible!

This is the Finalized Robot taking it to a microwave.

We will be competing at Robogames 2010 in San Mateo California on April 23-25th!
