Monik's bot¶
Introduction¶
This project was proposed by Thierry Bombardier, it is a robot controlled by a smartphone or a line of stickers. It will be able to extinguish a candle, to draw or to take a ball. The goal is to make a pedagogic robot easy to program and to assemble.
Hardware¶
Most of the hardware has already been designed on FreeCAD and the electronic solutions were chosen (ESP32 and stepper motors).
The first step was to make a step by step documentation for the assembly. We used FreeCAD to crate images and videos showing the assembly.
- Assemble the motors on both sides parts (be careful to place a motor for the left side and one for the right one. The, use screws to attach them.
- Then put both sides on the bottom part and glue the reinforcements on both sides of the bottom part (glue them only on the bottom part, not on the sides).
- When the glue is dried, you can screw the sides on the bottom.
- Do this on both sides of the robot. Be careful to have the motors axis on the robot outside.
- Add the top part, glue the reinforcements and screw them.
After all of these, put the wheels and the electronic cards on the robot.
Software¶
The software was not created yet, it will use a ESP32 connected to a smartphone with Bluetooth or connected with Rx/Tx pins to a light detector for the sticker programmation. The idea is to put a switch to choose between the smartphone and the stickers, an object orinted approach will surely be the best solution.
