AutoBalance: Week 2


What we have done:


We have discussed and established our working methodology and decided to follow the V-model. We have defined our requirements and graded them into A,B and C levels. We did further research on the subject and what is needed for the system stabilization. As well as the components functionality. We shared our thoughts about how the system and design would look.

Requirements:

“A requirements”

  • Design the entire motorbike prototype in SolidWorks, including all main structural and mounting components.
  • Assemble the “chassis”, install the “wheels”, and connect them to the motor to enable basic movement of the prototype.
  • The system shall deliver 10 minutes of usage time
  • The motorcycle shall be able to communicate with a remote controller

“B requirements”

  • The motorcycle must maintain a balance while stationary at least 5 seconds
  • The motorcycle shall maintain balance while in motion for a minimum of 5 seconds without external support
  • Integrate steering components to allow directional control
  • Add suspension elements, including springs and shock absorbers, to improve stability and functionality
  • The response time between the controller and the motorcycle shall be less than 100 milliseconds
  • The motorcycle shall be giving feedback in less than 50ms from when its down
  • The motorcycle shall maintain balance while in motion for a minimum of 5 seconds without external support

“C requirements”

  • Install as many additional real components as possible to make the prototype full functional and representative of a real motorcycle
  • The motorcycle shall fully stop when a object is 0,3 meter away
  • The motorcycle shall reduce speed when a object is 1 meter away
  • The motorcycle shall not be faster than 10 km/h

Findings:

We found key components that is needed:

  • 3S LiPo battery
  • Dc Dc buck converter
  • Microcontoller
  • Motor driver controller
  • 9-axis IMU

Acquired parts:

In the first round, the parts we got is:

  • 1 Servo motor
  • 1 Microcontroller
  • 1 Breadboard
  • 2 DC motors
  • 1 IMU sensor
  • 2 Driver motors

Next steps:


The data and electro part will focus on system design, simulation and the coding logic. While the mechanical part will work on sketches and design.

We will aim to develop a prototype within a 3-week period. To lay down the foundations and integrate with the system further.
