DIY Tank/Robot - core electronic/motor parts

[rbeckett]

Hi all!

I have a project I've been asked to assist with - Basically building a large Lego 'robot' for a presentation. It will be up to a meter tall, and probably weigh 5-10kg. The frame/Skin will be all Lego parts

I'm very familiar with Lego RC products/motors, however I don't think they will be strong, fast , or reliable enough for this project.

I'm capable enough to design the mechanics, and RC -> Lego connections.

The design will have tank treads, and basic controlled arms (raise/lower), and rotating head.

What I'm looking for is a DIY RC Tank kit that includes:

• RC Controller
• Receiver/Speed/Motor Controller
• 2 Drive Motors
• 2-3 secondary motors (arms/head)
• easy to remove/recharge battery pack

Are there any 'ready to go' kits from online hobby shops/aliexpress etc?

Ultimately I need something that the owners of this build can just switch on, and start driving

Also, if there are any other subreddits/forums that might be helpful to ask in, please let me know!

thanks for any help!

I don't know of any DIY product that does all you require, but a few years back HiTec offered Arduino controlled servo operated robots. Also, eBay and other online sites used to offer robot tank chassis kits by SZDOIT. This one I assembled with one of their chassis using Heng Long tank electronics to control tread operation and camera rotation. Too small for your ideas, but food for thought at least.
