tanks and robotics platforms

I was in Walmart today and saw a great deal that'll be loads of fun and might be exceptionally useful to someone with more skill in electronics than I. A 1/9th scale Abrahms M1A2 tank for $80. It was originally $200. The battery in it (a 12V 7Ah) is worth around $40 so it would be worth buying just to retrieve the lead/acid combo. This is a relatively lifelike model from 21st Century Toys. I couldn't find any info on their website about it so I assume it was built exclusively for Walmart. It is amazingly huge: 3' long with a turret that measures 12" by 16". The battery takes 18h to charge, so we haven't run it yet. It'll be interesting to see how well it runs and for how long.

I haven't taken it apart yet but it looks like it will easily fit a laptop and GPS. I'd bet with some skill it would be a fantastic, cheap robotics platform. If the boys let me, I'll take it apart and post some more pictures and specs on its mechanics.


  1. Yeah, I wanted to buy one, too. 2 poor. I thought about Vex micro as brain. Rig the cannon barrel with a pump-driven water cannon and challege 'em neighbor kids to a water war!!! WAH
    Have fun!

  2. Kool post! I was looking for a tank of that size (or bigger), but had no idea that Walmart carried those. I suppose that, wallies is no longer selling these, cause I haven't seen them. If you know any links or anyone that is willing to sell them for a reasonable price, please let me know. (
    I have a really cool project that i was going to do with them.
