Hacking the WowWee RS Tri-bot Remote: See What's Inside

Remote

Welcome again to another "rip-down" article. This time, we will start with the Tri-Bot’s remote. In this article, I will not tell you how to use the remote -  but rather, give you pointers on taking it apart and showing you what the tilt sensor does.  As well, I will give you the wire color code for each movement.

Let’s start by removing the batteries and the 6 screws that hold the cover in place.  Notice that the 2 screws in the battery compartment are smaller than the other 4 screws.  You must put these back in the right place;  otherwise, you will strip out the plastic screw holders and your batteries will not fit back in properly.  So, let’s take a look at the screw removal and compare them. 

Once the screws are out, you're ready to open the remote and have a look inside.

The tilt sensor is the part that is taped down with the wires.  You can remove the tape and look closer at the tilt sensor.

First, remove the tape and the 2 outside screws that hold the sensor in place. The 2 inner screws hold an extension for the sensor.  Let’s take a closer look.

There are 5 wires that control the tilt functions and these are as follows:

  1. Yellow controls the right movement on D4 {diode #4} on the main control board
  2. Brown controls the Down movement on D3  “
  3. Red controls the Left movements on D2       "
  4. Orange controls the Up movement on D1     "
  5. Green is your common Vdd power source     "

What this tells us is that every time the steel ball inside hits one of the sensors, it sends a HIGH logic signal to the onboard CPU when the trigger is pressed in order to engage these functions. If you turn this sensor around, then all the functions will be in reverse.  That can be a benefit if you like to look at the front of the Tri-Bot while you operate him.  As such, be free to make this change if you choose.

The remote has 2 IR sensors on it, as you can see from the photos. The round one is for transmitting its codes to Tri-Bot, and the flat one is for a narrow beam for the HOME function.  These codes are transmitted at 38 khz and has a 12 bit data stream, just in case you wanted that information.

In the image gallery you will find more pictures of the rip down. Also remember that when you reinstall the IR’s, make sure to look at the picture below and install it this way to make sure your board is in the slot when you put it back together again.

I hope you enjoyed this small article and if you have any questions feel free to ask away.  Thanks again for all members that follow my articles and also to RoboCommunity for allowing me to post these for your enjoyment, and to growyour knowledge of the insides of robots and their remotes.

Stay tuned for the full rip-down of the Tri-bot... coming soon to RoboCommunity!

nice job

Thanks Currahee for the nice comment. This article may be added to reveal more in site on how it really works from the board level, but since I have not posted an article for awhile, I thought "and Commander Pete as well " that a small intro would do fine till the Tri-Bot rip-down is out..

I lost my remote for tribot. Where can I get with reasonable price?
