LinkShield: The next one (R1->R2)
Opened this issue · 5 comments
This issue lists all the potential ideas and changes that should be done when planning a new release:
- Mark the pins of the servo for easier soldering and assembly on the silkscreen.
- Diode footprint has the cathode marking upside down. (@martinvrican)
- It would be good to have information on the angle of the tip, instead of acceleration. An IMU would be probably a better choice than a pure accelerometer.
- It would be better to have a motor without and internal feedback and solve the feedback in code ourselves. One possible solution would be to take an analog servo, convert it to "continuous" rotation servo (leave the mechanical stops intact) and use the pot signal for feedback (in lieu of an an encoder). This would better represent the 4-th order state-space model that everyone seems to be using (angles for motor and tip, angular velocity of motor and tip).

Awesome, thank you @martinvrican

The linkshield can be tested on the B&K Electrodynamic shaker we have in the lab. Also, it would be interesting to see how the LDV can be used to calibrate the gyro/accelerometer! So for this one, we actually have great tools in the lab.
