The next step to expanding my future robot army was creating the Otto Quad. It resembles the original Otto model, with the exception of having four legs instead of two. Below is the image of the final product. One of the main difficulties was adjusting the parts so that they could fit together. Since I…

Otto Reacts to Signals From a TV Remote
The next step after testing out the walk cycle is to have it be controlled with a TV remote. In order to do this, Otto needed an infrared sensor, which will allow it to receive signals from the remote. Then, I used the infrared library for Arduino in order to convert the signals sent by…
Otto Walks On Its Own!
In order to create my own walk cycle for Otto, I needed to see how the walk cycle was done within the blockly software. The video below shows the most basic walk within the software. The speed is set to slow.
Teaching Otto to Walk
After testing a program using the Otto blockly software, the next step was to manually teach it to walk. I used the set up with my remote, and connected it to each of the four servos of the robot. Using the serial monitor, it will be easy to record the positions of the servos. This…
Otto Assembling
After testing the servos with the remote, I started to assemble Otto, using the manual on their website. During the process, I had to pay special attention to connect the servos to the correct ports. They had to be calibrated correctly before doing so. The 3D printer that I used wasn’t very precise, so there…
Analog Input Blink
I used an example from Arduino.cc to practice receiving analog signals through the analog inputs. In this example, the wait time between the blinks of the embedded LED are going to be sent to the Arduino UNO board from the potentiometer. The potentiometer sends voltage to the analog input, which in turn converts it to…
Otto DIY – Walking Robot Project
Otto DIY is an open source robotics project. I have already 3D printed the leg parts of the pre-made model, and prepared the stl files for printing using Tinkercad. After the rest of the parts are printed, Otto will be ready for assembling. I’m planning to teach him how to walk by creating movement functions…
