Iron Man 3 4wd All Terrain Chassis

Help & Support Robots & Kits

Hello,

I was wondering if there was any news on when the Iron Man 3 4wd All Terrain Chassis will be available?

robotshop.com/en/iron-man-3- … duino.html

Also, I am looking for recommendations for a motor driver for this chassis.

The Iron Man 2 recommends this: robotshop.com/en/sabertooth- … river.html

I am new to this and was concerned about the fact that it is a Dual motor driver. Will this work with a chassis using 4 motors?

Thanks for any help.

We should have new stock of the chassis around the first week of April. It’s best to place your order which effectively reserves stock for you.
The Iron Man 3’s motors will consume around 1A each under load, while the Sabertooth can provide up to 12A per channel.
The Sabertooth 2x5A would save you a bit of money and still work well: robotshop.com/en/sabertooth- … river.html
You would connect both motors on the left to one channel, and both motors on the right to the other channel.

Thank you for the information. I have placed my order.

Another question:

What battery setup do you recommend for this motor driver and 4 motors?

I have the traditional 6-Cell NiMH Battery will these work? Or do i need to build a custom pack?

Thanks a bunch!

The motors include operate at 6V nominal, so if you can use a 6V, you’ll get the highest efficiency. A 7.2V is likely ok as well. You don’t need a custom pack, but be sure the pack can provide at least 4A continuously. The capacity will affect the size and weight, as well as the robot’s operating time between charges. One of many possibilites:

Ok… Last question… The Iron Man 3 says that the size is:

Size: 267mm × 278mm × 80mm

Is this inclding the wheel base or is this just the chassis? If it includes the wheel base then how does the chassis size of the Iron Man 3 compare to the Lynxmotion Aluminum A4WD1?

If the Lynxmotion Aluminum A4WD1 has much more room for gear then i may change my order. Also, it seems the both have the same weight capacity.

Thanks for you help!

The main chassis (bracket) measures 5.5" (14cm) wide x <8" (20cm) long x 2.25" (6cm) high.
The A4WD1 chassis measures ~20cm wide x ~24cm long x ~5.5cm high. The motors used in the A4WD1 are larger and more powerful than the Iron Man.

Hope this helps.

Excellent. Thank you for all your help. My order is made and being shipped.

I do have one more questions. For the most part this project will be controlled by a transmitter and receiver. Can you recommend a transmitter and receiver combo that will be enough to control:

Forward/Reverse
Right/Left
Two sensor servos

and possibly a robotic arm.

Thanks!

Forward / revers and left / right only require two channels.
The sensors are almost never operated via RC - what would they do?
The arm is the main issue in that if you want to control individual servos, you need a degree of freedom for each.

If you ordered the A4WD1 + AL5, you can work with the BotBoarduino + PS2 controller, which operates very differently than an RC remote:

Some setup and programming will be required.

Awesome… I didn’t mean the sensors would be controlled by the servos. Ultimately, i will be adding a camera on a servo swivel. This data and other similar data will be collected on board.

Thanks for everything… I am sure i will have other questions. You have been a big help.

Ok… Last question i promise.

I have a traditional 7.x volt RC Traxxas battery. Would this work for the A4WD1 or do i need a different source of power.

Thanks!

We are happy to help. The servos on the arm are best operated at 6V, while the DC gear motors in the A4WD1 are 12V nominal. a 7.2V battery is therefore not idea for either of these uses, so we would not suggest trying to reuse it but instead keep it for a future project.
