14. Radio-controlled Robot

The new challenges

We consider our tank-robot project as a very successful one - our creature can be nicely controlled remotely over Wi-Fi, or navigate around in the autonomous mode avoiding dangers and collisions. Still, there are questions which we could not answer:

• Remote control over the Wi-Fi lags even if you connect your agents directly. Is there any better way to control the robot? Can the Radio Controlling system be the answer?
• Do you really need to purchase expensive factory-made chassis, or there is some better way?
• Could LCD displays be useful for a small robot?
• Is it hard to use Li-Ion battery in the project?

To answer these questions - we decided to build a new robot, which will be a lightweight peer for our tank.

7. Sounds Generation

Our robot learned how to crawl. Now it is time to give it a voice. It is obvious that even well-known R2D2 became famous also because of his magnificent trills and beeps. Our robot cannot miss this part.

There are lots of inexpensive sound generation modules which can be integrated with Arduino. Including even modules which can play MP3 files from the built-in micro-SD card.

Currently, we have nothing like that. But still, there is a way do beep.

From the old broken toy we extracted a beeper - I believe in any house with kids you can find a couple.
