| [[Design overview]] can be found here.
| | Figur 1. Version 2 of Regbot. |
|
| |
|
| REGBOT comes in 2 versions:
| | == Overview == |
| * version 1A - with robot number 1..15
| |
| * version 2B - with robot number 16..36

| * robot: svn://repos.gbar.dtu.dk/jcan/regbot/regbot
| |
|
| |
|
| On a Linux computer do something like this:
| | [[Regbot GUI]] installation. |
| svn co svn://repos.gbar.dtu.dk/jcan/regbot/regbot .
| |
| svn co svn://repos.gbar.dtu.dk/jcan/regbot/qtgui .
| |
|
| |
|
| ==Install software==
| | [[Regbot hardware board]]. |
|
| |
|
| Get the regbot.exe from the course homepage, place it in a directory, this directory will be default for configuration file and result files from the robot.
| | == Install notes == |
|
| |
|
| A driver must be installed to get in contact with the robot - see [[installation in windows]]
| | This section is primarily installation notes and more detailed descriptions not usually needed by the end-user. |
|
| |
|
| The driver will create a com-port when connected - most likely com3 or any higher number.
| | [[Regbot command interface]] - command list. |
| When the robot is disconnected by unplugging the cable, then the client needs to be restarted if it was connected when the cable was unplugged (no connection detect in windows).

| ==User interface==
| |
| | |
| The user interface can configure and run the robot, as well as inspecting almost all values on the robot. Written in python using Qt GUI library.

| Hardware blockdiagram.
| |
| Most blocks are off-the-shelf hardware modules from PJRC (Teensy), Pololu (motor, driver and buck-boost converter) and Sparkfun (IMU).
| |
| | |
| A line sensor is planned, but not implemented yet.
| |

| Overview of software data flow. Yellow is control blocks.
| |
| Green is hardware (motor and sensors), Light green is calculations. Light blue is obtained values.
| |
| Gray is input values.
| |
| | |
| Sample time for all controllers and data values are 1ms.
| |
| All software is written in c++, based on Arduino libraries.

| Component placement and values (in red) are shown here.
| |
| Plug connections are shown in blue.

| |
| | |
| The Sharp IR sensor output is not connected to an AD converter input.
| |
| | |
| The IR sensor voltage divider output should be between 0 and 1.2V,
| |
| and could be connected to A0 and A1 (used to be feedback from motor-controller).
| |
| Unfortunately a plug can not be mounted (space conflict with USB plug).
| |
| | |
| The orange wires are patches (line sensor low power at pin 32 and from IR sensor to A0 and A1).
| |
| | |
| ==Install hardware - version 1A==
| |
| | |
| The motor and IMU wires are mounted as shown here.
| |
| The IMU uses 4 wires only, so only the rightmost pins (1..4) on the main board are used.
| |
| | |
| [[File:motor-imu-wire.png]]
| |
| | |
| Pin 1 on the IMU is as shown here
