Wireless communication with robot

mini's picture

I am making a simple robot, and am using a relatively cheap RF transmitter and receiver to send commands to my robot. Essentially, the transmitter end would send data from an AVR MCU via its UART to the RF transmitter, and a similar setup on the robot would pick up the data.So what I am confused about is how this whole process works. I mean, suppose I have four motors on my robot which all need to be controlled individually and at the same time. How would I accomplish this?

What's the best motor controller for tiny robot

I want to build a tiny obstacle avoiding robot using a 3v coreless DC motor. I've been using this L293D to control 5V motors and up, but I can't seem to find a motor controller that works with motors below 5V anywhere. I also have 3V two-step motors, but I would much rather use the 3v coreless DC motor if possible:L293D-Motor-Driver is a typical Motor driver or Motor Driver IC which allows DC motor to drive on either direction. L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction.

Femisapien - looking for schematics or troubleshooting tips

My daughter's femisapien will no longer power up.  When it's turned on, only the red wrist lights come on.  There's also a problem with one of its arms, but I'm not going to worry about that unless I can get the electronics working again.So, I'm looking for schematics, or troubleshooting tips.  I've already swapped the batteries, checked the fuses, and checked for broken wires.  Beyond that, I'd need a schematic to know what and where to probe.Any help would make me (and my daughter) very happy!Thanks in advance.

I dont see many people advertising anymore that they work on thier own roboquads I have a number of them and some need repair are there still people out there that work on these,,or atleast give me some advice? I have 2 red ones and two white ones that need thier legs repaired or atleast the switches reset on the motors? I also have several other robots needing repair and yep they are wowwee robots.
