• Dashboard v1.0

  Leandro • 12/30/2020 at 13:44 • 0 comments

  To help in the developmento of the project I added a simple dashboard in the ESP (based on Vue JS) to help control the robot and be able to see the stats of the robot.

  For now is only implemented a card to send the motor  speed, however it can be added new card to display any information from the robot, as more information is needed I will add other cards.

  Also the web app will be use in the future to send an image using OTA (that is the purpose of the "settings" page which for now doesn´t have anything).

  One of the great things about using Vue (with vuetify) is the the webpage is responsive and works great either in a PC as a mobile.

• New control board

  Leandro • 09/26/2020 at 14:44 • 0 comments

  The new control board rev0.2 arrived!!! All the components were soldered and the new board was tested in the robot.

  This new board will speed the development since the lidar, ESP and motor have different voltages, so with this boars is possible to test and development directly in the robot.

  With this upgrade all the logical and control board are done, the last hardware need it is the batterry control board, which if anyone could recommend any design I would much appreciated! (the plan is to use 3 series and 2 parallel, total of six batteries).

• Lidar testing

  Leandro • 07/01/2020 at 01:11 • 0 comments

  Finished tested all the hardware interface with the TTGO t-display board, and send the pcb to manufacture.

  
  Now I start to develop the code to interface with de Lidar. To help coding I solder a simple board to interface the Lidar with ttgo, tested the pwm which works fines, for next few days I will work on implementing the protocol for the lidar.

• June 2020 - update

  Leandro • 06/28/2020 at 14:22 • 0 comments

  Currently I am on the stage of upgranding the control board to use the TTGO t-display board, which has an integrated display which will help in the development of the prject and also is a cheap and easily available board.

  Yesterday I finished the board v0.2 with TTGO:

  And in parrelel I am testing all the interface with the other parts of the robot before sending to manufactured (GPIO, PWM, UART).

  The pcb files are already available in github:
