Introduction
OpenMR is an OpenRave Modular Robots plug-in for simulating the locomotion of modular robots. It consist of controllers, robot models and examples.
Hierarchy of Controllers
The controllers are hierarchical. At the lowest level there are the controllers that interact directly with the joints, seting their current torque, position or velocity. Typicall level 0 controllers are: P, PD, PID...
Level 1 controllers set the sequence of reference signals for the level 0 controller in order for the robot to move. Examples of this kind of controllers are gait control tables, sinusoidal generators, central patter generators, neural controllers and so on.
Level 0 controller
Currently there is only one level 0 controller in charge of setting the joint's reference positions.
Servo controller
This controller implements standard servos, which are controlled by setting its reference position. Internally It has a P controller
- API
| setpos s1 [s2] | Set the reference position of all the robot joints, in degrees, in the range [-90,90]. If the robot have N joints, there have to be N arguments. |
| setpos1 servo pos | Set the reference position of one joint. The argument servo is the servo number, starting from 0. The argument pos is the reference position (in degrees) [-90,90] |
| getpos1 servo | Return the current servo position (in degrees, in the range [-90,90]. The argument servo is the servo number, starting from 0. |
| getpos | Return the current position of ALL the robot's servos (in degrees, in the range [-90,90]) |
| record_on file | Start recording the servo position in the specified file. It will generate an octave file |
| record_off | Stop recording. The octave file will be generated |
Level 1 Controllers
- Neuralcontroller
- Generic controller
- Harmonic controller
- Sinusoidal controller
- Others...
