Holobot week 48
Kjartan & Stian We are using Arduino Nano 33 BLE Sense and it has a bluetooth module that has the GATT profile hardwired in it. To connect to the Hololens we need a HID bluetooth profile or a A2DP bluetooth profile. HID(Human Interface Device Profile) is bluetooth devices that provides support for devices such as…

Week 47
#1 This week we are working on further developing the tension based system.Now that we are closing in on the final weeks, the design is coming along. It will be a dual spring design, where a spring is connected too a new launch-plate The plate will be stabelized by 2 supporting beams which are integrated…

Fredrik og Gustav har denne dagen forsøkt å koble opp de forskjellige sensorene. Det ble først forsøkt å koble opp med Arduino Nano, men det var en del enklere med Arduino Mega, så dette ble gjort istedenfor. Ved å koble opp lys-, temperatur- og vannstandssensor ble det funnet ut at temperatursensoren tok oppimot et halvt…

Week 12 (09.11 – 15.11): Automatic watering system for plants
Software (Marius): This week I have been working on some power savings features for our system. It seems to be several ways of doing this, and how much power can be reduced by using these methods seems questionable. Some of the methods I’ve looked into are: Using low-power libraries (Most of the libraries I’ve come…

Holobot week 47
Adapting to an issue (Mads) The last weeks I have been more concerned with developing the mechanical aspects of the Holobot rather than writing. Countless hours has been spent designing, printing/cutting, assembling and testing with mixed results. I wanted to create a module based track(beltemodul) which could easily be installed on different vehicles and robots.…

Sprint 11
Maskin (Simen): Continued the design of the servo compatible parts for the arm. Trying to find a way to print these parts. Also making a way to place a spring into the hand to keep the cards under pressure, while also needing to make sure only one card is ejected at a time. Elektro (Sondre):…

Ninth sprint – Puck Buddies
Gaute 3D printed some of the assembly-blocks so I could verify that the measurements were correct, and they fitted perfectly. So for the coming week we can start printing full scale. Halvard This week I have mostly been slicing and 3d- printing parts for the machine. This work is mostly passive work since most of the time is spent on the actual…

Det ble denne dagen konkludert med at istedenfor å fortsette og forsøke å gjøre aquariet tett om igjen og om igjen på tilnærmet samme måte, og gå i Einsteins galskapsfelle, ville vi heller finne på noe helt annet. Det ble indentifisert tre alternativer, enten bestille en bunnplate i glass, bruke en ny pleksiglassplate, men bruke…

Sprint 10
Common: We have made some models to better represent our system, what we want it to do and how it should be set up. Physical models showing the main components in the subsystems that they belong in and the different levels of tasks that we want our system to accomplish. Maskin(Simen): I did not get…

Week 45
This week we found out that our current system is suboptimal, so we are making some mayor changes. Table of contents:1. compression spring vs tension springs(Daniel) 1. Tension V.S compression springs Now that I have done some testing and prototyping, I have found that compression springs are not at all suited for our project. The…
