Vi har fått utdelt en Arduino nano, en MPU 6050 sensor, en bluetooth mottager chip, to dc motorer, en L298 motordriver og et koblingsbrett. Vi startet med å samle informasjon om prosjektet, hvordan selvbalanserende roboter fungerer, fysikken involvert og hvordan komponentene fungerer.

  The servo does not respond as we wanted. Installed Digilent WaveForm to explorer,test and take measurements  to see the output from raspberry Pi on  the oscilloscop. Clockwise pulse width of 1.5ms Counter clockwise pulse width 1,16ms  

7.11.2017 Gruppen møttes i dronesonen og begynte å jobbe med mulighetene for å koble sammen flere motorer, slik at vi kan kjøre alle fire motorene samtidig. Dette ble gjort ved å modifisere koden fra forrige gang. Vi måtte også finne en annen strømkilde enn 9-volts batteriet som vi har brukt tidligere. Vi fikk litt problemer […]

Det jobbes iherdig med å få koden til å fungere som vi ønsker.  Vi har testet ut forskjellige PID verdier og diverse andre verdier. Dette viste seg å være en utfordring. Men vi holder motet oppe (bl.a. med pepperkaker) og fortsetter å gruble på problemstillingen. Klikk på linken for å se hvordan roboten foreløpig ser […]

We have encountered problems with our raspberry pi noir camera, so we started experimenting with a new camera. This camera is an ir camera, and not just a regular camera with the ir filter removed. This is a better alternative, since our images are not affected by the visible light in the room. Our early […]

Hello world. We’ve now finally started assembling the car. The chassis is assembled, and wheels have been attached. The steering mechanism is attached as well. we’ve also worked on programming the lidars and further developed our system. Its not long until we can start assembling the electronical components to the car and start testing. see […]

Smart mirror – Software update Last tuesday (31.10.2017) we recieved the soundcard, and configured the Raspberry Pi to use it as default sound card. Today we ordered a mirror foil, expected to be delivered between 16th and 22th of November. We made good progress on the software part of the smart mirror today. The face […]

The frame as it was shown, is printed with the Ultimaker at school (Figure 1). Figure 1 First prototype 3D printed frame   The outer dimensions of the frame were almost good. The following dimensions are changed (Figure 2): The arm supports were both too tight, so these are made wider The frame was too […]

Hello world! today we had short meeting in the morning where we discussed how long until we could start putting pieces together. We found out that by next week we should be able to start putting the steering mechanism together. Computer had implemented a stepper motor for turning the car. We are not sure if […]
