Optical Isolation Board Final Version

Below is the first design of the opto-isolater this was made off our breadboard designs and only controlled one motor at a time.

This was then redesigned to accommodate for all the motors.

Motor Driver Board Final Version

We have re-produced the motor driver board for all five motors based on our prototype design below.

Here is the final circuit design for the motor driver board, this has been developed as PCB and can be download on this blog.

How to connect the raspberry pi with the camera?

First you open up the pi's connectors on the pi by pulling out the tab then you take the camera module and you must make sure the connectors on the flex are facing away from the Ethernet port which is next to the pi's connectors and then just place the ribbon cable into the connectors. Cameron designed and built a mount of the camera to have a secure place on the robotic arm, he achieved this by using a software called solid works. When he finally had the finished design he used the 3D printer to create the mould.

Sut i gysylltu yr Raspberry Pi gyda'r camera?

Yn gyntaf byddwch yn agor yr cysylltwyr y pi trwy dynnu allan y tab, yna byddwch yn cymrud y modiwl camera ac sicrhau bod y fflecs ar y cysylltwyr yn wynebu i ffwrdd y porthladd ethernet sydd yn ymyl cysylltwyr y pi. Wedyn gosod y cabl rhybun i mewn i'r pi. Cynlluniwyd a adeiladodd Cameron mynydd i'r camera cael ei lleoli yn man diogel ar y fraich, defnyddiodd e meddalwedd or enw 'Solid Works'. Pan gorfennaf Cameron y dylunio roedd yn barod ir 3D printer i printor dyluniad.

Brief Update On Whats Going On

English

Since the last time we updated, there have been quite a lot of things that we've been very busy with, always to trying to add to the functions and uses of the Robotic Arm. Recently (myself) Jesse, Harry and Matthew have all been trying to incorporate a switch into the already mess of wires connecting the Raspberry Pi and Robotic Arm together. The reason we've been doing this is because we want the Robotic arm to move in a certain sequence whenever the button is pressed. It’ll run through a program that will cause it to move into a specific position and then capture an image of whatever is in front of it, with a small front mounted camera. Once the picture is taken, the Arm will then move back into its original position. Quite a lot for the Arm to do with only one button press, that’s why we’re still working on it. Hopefully by the next time we update this will be working perfectly.  

Twitter

English

Recently we have created a twitter account for the robotic arm. The purpose of this was to display photos when people were to tweet a specific hash tag. The hash tag we chose for testing purposes was #30PI. The code that we wrote was written so that when someone tweeted our hashtag, our program would search twitter for #30PI the camera would activate and take a photo and instantly upload it to twitter. This is a great way for people to understand why we are using this robotic arm when we present our work in the Celtic Manor. For the show you can activate this yourself by using #SayRaspberry. Come and give us a follow on twitter the check out on more updates - @PiRobotic

Yn ddiweddar rydym wedi creu cyfrif twitter gyfer y fraich robotig. Pwrpas hyn oedd i arddangos lluniau pan fydd pobl yn cael tweet tag hash penodol. Mae'r tag hash rydym yn dewis ar gyfer dibenion profi oedd # 30PI. Y Cod yr ydym yn ysgrifennu ei ysgrifennu fel bod pan fydd rhywun yn tweeted ein hashtag, byddai ein rhaglen yn chwilio am twitter # 30pi byddai'r camera activate a chymryd llun ac yn syth lwytho i fyny ar twitter. Mae hon yn ffordd wych i bobl ddeall pam ein bod yn defnyddio hwn braich robotig pan fyddwn yn cyflwyno ein gwaith yn y Celtic Manor. Ar gyfer y sioe, gallwch activate hyn eich hun drwy ddefnyddio #SayRaspberry. Rhowch dylynol i ni are twitter i gweld mwy o ddiweddariadau - @PiRobotic.
