CamJam Edukit #3 Robotics

Thu Jul 26, 2018 5:40 pm

Hi everyone
I’ve just signed up to raspberry pi.org website as I was told it’s a very good website for getting help.

I’ve just finished building the CamJam Edukit # 3 Robot, I’ve worked through all of the 9 programming sheets,
after I finished writing the programs and saved the file I would then test the required components ( motors, line dectection and distance sensor) these tests were carried out on my work bench, so for example if I was testing the motors I would connect the motors to the drive board and run the program via the raspberry pi 3 and my 22” HDMI TV
I’ve now put everything together and have a completed robot.

My question is how do you guys run your robot? do you plug in your HDMI TV and keyboard into the raspberry pi run the program then disconnect the HDMI cable & Keyboard from the Pi and then let it run or I’ve I got to purchase a small 3.2” TFT Screen and have it connected all the time?

Welcome to the Raspberry Pi forums.



My mode of operation:

Associate the WiFi interface on the robot-mounted RPi 3 with a convenient WiFi access point. Then from a 'desktop' (possibly laptop) machine on the same network you can use ssh to get a remote shell prompt on the RPi and 'drive' the robot from there. Raspberry Pi Foundation documentation about wifi configuration here https://www.raspberrypi.org/documentati ... /README.md, and about remote access here: https://www.raspberrypi.org/documentati ... te-access/

If there is no accessible or shareable access point, you could configure the robot-mounted RPi to advertise its own WiFi access point, and directly associate a laptop Client machine with it. Then use remote access as for the previous solution. Raspberry Pi Foundation documentation on WiFi access point configuration: https://www.raspberrypi.org/documentati ... s-point.md

Hi B.Goode
Thank you very much for the information and the links you have sent me, I will work though the information and hopefully will have a robot that is remotely controlled.
I’m a retired electronics engineer by trade due to ill health, I’m pleased with the robot I’ve built as I’ve used most of my own components and not the breadboard and wires etc that came with the CamJam Edukit # 3 Robot, I did get a bit confused with the SSH setting, I did contact the Pi Hut for information but they didn’t explain things to me very well.

Once I get the robot running I would like to try and use a PS3 controller to control the robot, but I need to find the software information on the Pi Huts website for programming the PS3 controller, so I’m sure I will be looking for more help.
Anyway thanks once again for your help.
Kindest Regards
Kevbo

A little off-topic, but hopefully helpful...

I am also a retired something-or-other, I no longer remember what exactly...

Dabbling with RPi and associated kit, and helping others here do the same is a way to keep my mind active and learning new skills.

I have always had good service from The Pi Hut. In fairness to them, they are an online retailer, not a Help Desk. Other than for something that is downright broken I would not dream of asking Currys/Dixons for technical advice!

The vast majority of what you need to know is written up on the Raspberry Pi Foundation documentation pages. But it can be difficult finding it. Volunteer helpers here can usually point you in the right direction.

Alternatively, you could go back to the place where you got the programming examples from (https://camjam.me/?page_id=1035#worksheets) - there are several examples of using both SSH and a PS3-alike controller on there.

Hi recantha2
Thank you very much for the information on the CamJam Edukit # 3 Robot and the Links.

I purchased my 1st Raspberry Pi 3B from the Pi Hut and a SD Card with NOOBs already installed on it, after playing around with the Raspberry Pi, I decided to purchase a couple of blank 16 GB SD Cards.
I purchased the SD Cards so I could teach myself how to install NOOBs, I formatted the SD Cards using the standard windows formatter, and I then installed NOOBs successfully.

1. Am I correct in saying that I need to re format one of my spare SD Cards using Etcher?
2. Should I install RASPBIAN onto the SD card?
3. Or can I use NOOBs which will allow me to use SSH
4. I can only find one type of RASPBIAN on the raspberrypi.org website but I’ve heard of people talking about RASPBIAN Stretch and RASPBIAN Jessie
Kindest Regards
Kevbo

Etcher writes an OS image to the SD card. That's not just formatting.
You don't need to format the card before writing it with Etcher
2. Should I install RASPBIAN onto the SD card?
3. Or can I use NOOBs which will allow me to use SSH
Noobs is not an OS; it's an OS chooser/ installer. If you install Noobs you would probably use it to install Raspian
Best is to just write Raspbian to the card, using Etcher. And you certainly can use SSH with Raspbian.
4. I can only find one type of RASPBIAN on the raspberrypi.org website but I’ve heard of people talking about RASPBIAN Stretch and RASPBIAN Jessie
Jessie (aka version 8) is the predecessor of Stretch (version 9). So you should write Raspbian Stretch to your SD card.

So in essence: download Raspbian from https://www.raspberrypi.org/downloads/raspbian/
Install it with Etcher using the instructions at https://www.raspberrypi.org/documentati ... /README.md
