Meet " Squeegee" , The Flooring Mopping Robot , Modified Radioshack Robie Jr

StorySkip to comments

This is a simple project that hopefully I wont over complicate. Since he Squeegee needs to get as close to furniture and the toilet and bathtub as possible this my be a challenge. After all we spend most our time trying to get our robots to avoid the objects in the room. Im giving new life to a radioshack robie jr rc controlled robot.

Ok first we need to see what we are working with..... I took the robot apart and removed most electronics and ran it through the dish washer. Now the robot looks very clean. I would like every ones opinion if I should use the dome or not.

I have a small problem , one wheel has damage to the rubber. I am going to consider using continuous rotation servos and the tires with them. Well see if I can work my magic and make these wheels work. Somthing very important is that the drive train is quiet as this is really not a entertainment robot.

Now that the robot is generally clean we can take a look at how much room I have to work with. A huge section of the robot is dedicated to 8 AA batteries from the original manufacturer. We will see but that could be a possible mountingamounting area for a big lipo battery.

We see if you dont count the AA battery box there is 7 inches high of space and 4 inches to the collar from the factory pcb.

Current Sense IC


This ~$5 chip, using a really tiny resistor and a built in high gain amplifier, outputs a voltage in proportion to the current passing through it. Put the chip in series with what you want to measure, and connect the output to a data logging device such as a microcontroller.

This particular schematic below can measure current use of a servo. But it can easily measure current from any other device with no modification - and even multiple items simultaneously too! The capacitor is optional as it acts as a voltage buffer, ensuring maximum continuous current.

Another link to look at that talks about current sensing.

Adafruit do a board too, I ordered one to test out on Melvin or Jarvis (and if it works well I'll get another). Simple breakout board, nothing fancy, INA169 Analog DC Current Sensor Breakout

Josh, do you still have that extra Robie Jr remote? I just bought my son a Robie Jr and it didn't come with one.
