The &DROID™ project started from a desire to learn electronic coupled with a lifetime fascination with robots...
I would also like to extend a welcome.
I was looking around on your website and read this:
"As I assembled this small kit chassis, I realized that it would be just as easy to build something on a larger scale."
I don't think it's just as easy to build a large robot as a small one.
I haven't built a large bot myself but from what I've read, controlling large motors is much more challenging and expensive than controlling small motors.
I can make a small robot with tape and foam board. A large robot requires strong materials and careful building to keep it from ripping itself apart.
Of course a lot of challenges remain the same with a large bot. Obstacle avoidance and navigation tasks are very similar with both small and large bots.
That's a great deal on a motorized chair you got. I'm going to keep my eyes open for something similar around here.
I look forward to seeing what you do.
