WARP (Wheelchair Assist Robot Platform) shows off it’s collision avoidance and “Drive to Destination” targeting mode at the Norwescon SciFi and Fantasy conference in Seatac on Easter Sunday.

No children were injured despite their aggressive nature towards the robot.

The robot was very patient with the squishy life forms despite their continued taunting.

Early testing of the new prototype. I am excited to share this as I have been working long hours bringing this concept to reality. It is moving around in a confined space pretty well. There is still a lot of work to be done, but it is getting closer. Very excited!

Check out the latest Mechanized Stroller.

Robotic Stroller Conversion Kit Now Available for Purchase

Seattle, Washington – October 8, 2012 – For those of you who have the all-terrain strollers, now there is an easy way to turn your stroller into an autonomous robot. Purchase Xandon Frogget’s kit and within an estimated 20 minutes, you can convert your stroller into a robot that will drive autonomously. Or you can put it in ARAS mode and let the “autonomous robot assisted steering” drive itself around and avoid obstacles. This kit is intended for geek moms, dads or anyone looking for a solid platform for learning and discovering robotics.

There are three kit configurations for sale: Basic, Medium, and Complete Kit. The basic kit starts with all the hardware you need including either a Kinect or ASUS Xtion Pro but the buyer must provide the laptop/netbook and the stroller. The Medium is all the hardware including either a Kinect or ASUS Xtion Pro and a Netbook, but the purchaser provides the stroller. The complete kit includes all the hardware, the netbook, and the stroller. The kits are expected to retail for $2,500 – $3,500, depending on the configuration. (* See update at bottom)

The kit connects easily to most jogging strollers that are similar to the BOB Jogging Stroller and does not require any destructive modification. When you are done playing, you can return the stroller to its original configuration unharmed.

The wheelchair motors are rated for up to 300lbs, in case you need to use it as a porter to replace your Sherpa. And did we mention it is so quiet and that you can drive it around the house at night while everyone is sleeping?

In the demo video, Frogget is using a rooted NookColor to control the interface, showing off some of the unlimited possibilities. The sample code is written in Processing and can be modified easily so that any hackable device can steer it including a smart phone or Wii remote with Wii Wheel. Using software like Apple’s FaceTime or Google+ video chat, the robot can be teleoperated and provide a telepresence for grandparents everywhere, including the zoo.

The robotics stroller conversion kits will be built-to-order beginning mid October 2012. Please contact sales@daddiorobotics.com for purchases or inquiries.

Update August 3, 2013: We have suspended our current stroller conversion kit in order to focus on the new prototype. Apologies for all those who had been dreaming of getting a kit for fall 2013. Check back as we have exciting news coming.

I needed some running lights for a robot I have been working on; Brake lights, Turn signals, accessory lights etc. After reading an article the other day on how to make your own infinity mirror, I got the idea to use it on the robot and give a depth effect to the lighting system. I made up a prototype to be sure the effect would be easy to reproduce and look nice. I then spent several hours cutting and creating the aluminum housing, sandwiching a row of 11mm addressable RGB LED’s between a mirror (on the back) and a one way mirror (on the front). I ended up with these four corner lights for the robot. There is still some finishing work to do before mounting them, but the infinity mirror effect looks very nice I think. Mostly the lights will be used to display status and movement intent and will be greatly subdued so as to not look like a Vegas show. Of course there is always robot party mode where the robot plays disco and creates an interactive piano on the bed for little girls to jump around.

MiniBob is an early prototype for the Mechanized stroller. It was designed for Robothon 2012 to meet the weight requirement of 50lbs. He weighed in at 49 lbs.

In this video MiniBob takes his first steps! One caster is easier than two. Yeah! Wish MiniBob well on his competition Saturday at Robothon. Please let there be grey skies Saturday so that Felix and MiniBob are not blind.

The twins jumping on the bed trying out my virtual keyboard. Using techniques from the book “Making Things See” by Greg Borenstein, I was able to create a virtual matrix that floats above the bed. As the girls move through the matrix it plays different sounds based on their location.
This is one of the first iterations. I was trying out sounds to get a nice interaction that would be easy for the girls to anticipate and would hopefully spark more intrigue. This was a pentatonic scale of a single octave offset by 1 across the matrix. It still sounds fairly difficult to anticipate for the girls, but I think the piano works well. Next I hope to add more music and extend it by adding the skeleton mapping to allow for instrument selection that produces the sound. The instrument will be chosen by the location of the hands when an event is triggered. If the hands are at the side it will play piano. If one hand is at the shoulders it will play a stringed instrument along with piano and so on.
I want to add thanks to my neighbor Brian for his help getting the piano sounds, and to my sister Lorri for instructing me to use a pentatonic scale as well as provide a useful placement those notes on the matrix.

I finally mechanized our Bob Duallie jogging stroller (won’t the girls be happy!) I needed a new chassis for an autonomous robot. One that could handle a larger payload. After adding motors to the Bob I needed a way to test them, so I added some distance sensors and wrote the software to allow the Bob to follow in front as you walk.

The bags in the front are ballast to keep the front from popping wheelies when I drive it up hills. There is a kill tether (that I am not holding on to.)

The laptop is being used to display motor performance, it is communicating via wireless zigbee to the stroller.

Presently the brains are made up of an Arduino Fio 3.3v connected via i2c to an Arduino Pro Mini 5v 16mhz – that handles the sensor data. It transmits motor control via serial to a Sabertooth 2×25 motor controller. The 2 motor’s are 100 Watt 24V Scooter motors. It is powered by 2 12V 7Ah Lead Acid Batteries. The Fio has it’s own 3.7 V 2000 mAh Lipo battery. The Pro Mini uses a 5v line from the motor controller. The chain it use are #25 as well as the sprockets to drive the wheels.

Web camera motion capture laser turret. Targets and paints the EL Wire butterfly very nicely. The butterfly I made using Electroluminescent Wire sewn onto an ornamental butterfly with fishing line.

http://en.wikipedia.org/wiki/Electroluminescent_wire

Laser Turret is a prototype robot I slopped together. I have been using it to learn how to program and understand wireless communication. It is built from a set of Surgical clamps, velcro, breadboards, plumbers tape, servo’s, ATMega328p and the laser torn out of a laser pointer.

Processing & Arduino code from Bob Rudolph’s Sentry Gun Turret. Thumbs up to him and his very nice code. The servo targeting via serial communication works great via Zigbee Wireless.

This is my first robot. It uses a development board created by my new friend Mike. It is made of wood, Velcro and screws. It has 2 servo’s for drive motors, and a bump sensor to stop. It uses a Ultrasonic sensor to sense distance. It has a motion detector tied into the loop so you can put it in sentry mode. It is programmed in AVR Studio 4, and the program is written in C.

One of my first projects was to create a 5x5x5 LED cube with some LED’s I bought from Fry’s. I made a jig to hold each row to solder. Then stacked the rows. I used the Maxbots board that Mike created, and wired the LED’s to the board.

Here is a video making of the LED Charlieplexed Cube 5x5x5 from 2009.

This is the cube running a loop programmed in C.
