4.0 out of 5 stars it is not going to replace your cat or dog - power issues and glitchy software
Reviewed in the United States on December 1, 2020
The idea that you can get a kit to make a walking robot from a Raspberry Pi was too much for me to pass up. I had several unused Pi boards laying around, so this seemed like a fun project. First of all, I'm a Systems Engineer by profession. I deal with electronics, electrical, thermal, mechanical, and software engineering on a daily basis. I would not recommend this kit to anyone that is not comfortable with mechanics, electronics, computers, programming, and the Linux operating system. That being said, this was one of the most frustrating builds I've done in a long time. You'll operations where you'll need magnification, 4 hands, and tiny fingers.

First of all, you need batteries - 18650 cells to be exact, and you are not going to find these on your local grocery store or hardware store shelves. Luckily, I had a few USB rechargeable flashlights that I could borrow these from.

About 30% of the documentation is how to setup the Pi. Basically just make sure that you have it setup with stock Raspberry Pi OS, it connects to WiFi, and you can VNC or SSH into the Pi. You have to enable I2C, Camera, and a few other things and clone their python code from a GitHub repository.

In the box is a surprising number of servos, packets of screws/nuts, circuit board, cables, and components. The plastic pieces are punched out of some kind of CNC cut plastic sheet material. They are taped into the sheets to keep them from coming out. Be careful here. It does come out easily if pressed straight out, but the material is quite brittle and I did snap some corners of parts removing them - but nothing that would impact function. There are some spares of critical components which is a nice bonus.

The build was quite interesting overall. Not how I would have engineered this kit. Very tedious, small, and next-to-impossible operations. You have to randomly (Yes, the instructions tell you to do it randomly) connect the servos, run a program on the pi to index the servos, and then assemble the legs while the pi is running and power is connected. You have wires going everywhere and it is a bit of a sh*t show.

The instructions are vague in areas, and then there are some sentences that are somewhat confusing due to the translation. Once you get the kit built, and all the servos correctly attached, it does have a somewhat fun and satisfying validation check of all the components.

After you have everything working, you then need to calibrate it. It comes with a paper sheet and extra calibration legs that you attach to the robot. You align the calibration legs to their places on the sheet, connect to the robot, and then fine tune each leg to the correct spot on the sheet using X, Y, Z adjustments in the calibration software. Once the calibration settings are done the robot is ready to walk.

It does not walk very fast or very far. The battery life is not great... maybe 7-8 minutes from a full charge if you are walking around a lot. The client software on Windows is very unstable and crashes often. The robot occasionally gets "tired" and won't let you walk for a while, assuming while it "rests" - mind you, this can be after walking only a few inches. It only walks well on smooth surfaces, and easily gets stuck on the edge of a very low/thin carpet. The camera is OK and does the job, the sonic range finder is somewhat inaccurate while walking around. The facial recognition, an impressive feature, is glitchy like the rest of the software. I had it try to recognize a person, but it was more interested in recognizing the door behind the person. Maybe this could be used for the robot to recognize it's location in a house by recognizing objects?

I had plans of making this into a smart roving robot that could navigate my house, take pictures of things, walk up and down stairs, recharge itself wirelessly, etc. Sadly, this robot, as it is designed currently, is not capable of these tasks. It is a fun toy to go put out by the cats and watch them stare at it as it clumsily shuffles around an inch at a time for 7-8 minutes while constantly restarting the client app after it crashes. Then, back to the charger for hours, until the next session.

I am using a Raspberry Pi 4, which does have the highest power consumption of all the Pi devices. I tried using the Pi Zero W which is supposed to work. However, the camera ribbon cable appeared to be incompatible with the one supplied. I am curious to see if using a lower power Pi would extend the battery life.

This kit took me about 8 hours to build, and I think it was worth it for the price. It was frustrating at times, but does look really cool when powered up and standing, and it is oddly satisfying to be using VNC or SSH on a "robot".

5.0 out of 5 stars Amazing Robot Dog Kit- a perfect gift and easy way to get into coding
Reviewed in the United Kingdom on October 10, 2020
Absolutely amazing Robot Dog Kit. Very easy to assemble and load the programs. High quality materials, relay motors have metal casing and are made to last. There is nothing cheap about this product. It takes couple of hours to finish the Robot assembly and set up the Raspberry Pi with all the correct settings as well as programming the Robot. The instructions are easy to follow but needs to be followed carefully and cant be skipped.
A perfect gift for anyone who loves electronics/robotics and an easy way for kids to get into the world of coding.
The Robot Dog can perform a number of tasks such as:
1. Walking Modes - Step Forward / Step backwards
2. Step Left / Step Right
3. Turn Left / Turn Right
4. Play a Sound
5. Recoganises Faces (different Face ID's can be added)
6. Relax Mode
7. Balance
8. Different LED light modes

We can further program the Dog to perform a number of tasks, possibilities are endless.

Very pleased with the product. I would highly recommend this kit.
