How can know if safe from burning out robot with more voltage?

Here is the situation, my friend have a Wowwee animatronic robot that he has been tinkering with, with the goal of hooking his arduino up to it so that he can control it from his computer.The problem is, using a multimeter, we've tested that the voltage on the robot's control lines/pins is 3.3v ; but the arduino outputs 5v through its pins.Will hooking up the arduino and using its 5v pins damage the robot?

WowWee REV vehicles rechargable battery packs

I purchased the Robot Enhanced Vehicles for my son this past Christmas. The vehicles eat through batteries so I ordered two rechargable battery packs. The problem was, they were both dead on arrival. I contacted WowWee and told them about it and they offered to send a replacement in January. Well February came around and I sent another message. I then spoke to a rep who I believe is the rep I am about to write this review about. The battery packs were sent quickly. However, only one worked and the other DOA.

Wireless communication with robot

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.
