Frame built for balancing robot. I used a 3mm acrylic sheet built in 3 tiers using stand offs. Motors, battery holder and electronic module boards are also fitted. The modules are a MPU6050 which is a 3-axis gyroscope and a 3-axis accelerometer combined, a L298N a dual H-bridge motor controller. Currently I have both an Arduino Nano and a ESP8266 onboard. The initial thought was to use the ESP alone but it looks like it wont have enough GPIOs (at least not without a lot of jumping through hoops). So currently going to use the Nano to control the robot and the ESP to communicate with it at least that’s the plan. However I am waiting on a couple of ESP32s coming from China these have built in Bluetooth. There is also the option of adding Bluetooth to the Nano. Watch this space.
The first project has been posted this is Installing WordPress on a Pi Zero W. I may document other projects I have done in the last few months but I will certainly publish any new projects. One project I will be publishing is a balancing robot. I have most of the parts for this. I’m still looking around for a frame and also not sure if it will be Arduino or ESP8266 based. This depends on if I want it to be autonomous where I might get away with using a Arduino mini or controllable through my phone or tablet or even both using a ESP8266. Of course I could use a Raspberry Pi but i don’t have one spare at the moment.
