Tasks accomplished:
- Ordering of most parts for the robot
- 3D printed the ears
- Attended and presented during the first sharing session
- Decided to use Wi–Fi transceiver to facilitate the communication between the robot and user end
During our discussion with Tony, we considered different possible ways to facilitate the communication between the robot and the user including using:
- Cellular data (GSM)
- WIFI using router or transceiver
- Dongle (“a lipstick-sized gadget that plugs into your computer and allows you to connect to the internet”1)
As much as each method has its pros and cons, we finally decided on WIFI using transceiver. The range dongle can reach is too short and WIFI using dongle is not strong enough. Cellular data is overly expensive and GSM cannot support live-time transmission of audio and video. Tony recommended using WIFI considering the limited funds we have.
We settled on the model TP link CPE 510 as it has a long range of about 15+ km. One challenge we faced with this model is that it has a dual directional antenna. To resolve this, we thought about fixing the antenna on the rotational platform on the robot and always rotating the antenna such that it always faces the base station. 😉
Some of the parts including the ethernet switch and the raspberry pi came few days after we ordered. We then thought about how we wanted to arrange the hardware together and how we wanted to test the raspberry pi.✌️
