jakkra / mars-rover Goto Github PK

Dear jakkra:

Thank you for your selfless sharing. Your rover is very cool. I also want to make one, but Fusion360 is very slow in China, and the license is basically not available. Is there a solidworks version of the car? Whether the bearings on the 4 driving wheels are missing, I wondered how to install them for a long time.

I'm trying to figure out how to print the head top connector & head rotator: I see that some bodies need to be exported as a single stl. One thing that is not clear to me is what bodies need to be exported/printed together in the red area here below:

Any hint? Thank you :)

Once again,thanks for all the hard work you have put into this project. I am interested in building this, but I am having issues sourcing a RC receiver and transmitter. I would like to know which ones you choose to go with.

hey ， genius i am fersh person about Mars-Rover , but i 'm very carazy about it , could i learn it good from knowing nothing?

Hi, i really like the rover, Nice project!
is there a guide for people that does not know how to program (like me) to control the rover remotely?

Hi Guys

I bought TowerPro MG946R's for the steering as stated in the readme but after printing the wheel rotors they don't seem to fit at all. Just wondering if I am missing something.

Hello,

the rover_back v1 f3d file shows a number of holes on the back part of the body (to attach reactor and antenna) and on the front part (arm). Since I'm quite new to fusion 360, how can the body STLs be exported, so that they include all holes?

Thank you

First off thanks for all the hard work you have put into this project. I am interested in building this, but I am having issues sourcing a 12v-to-5v-switching-voltage-regulators. I would like to know which ones you choose to go with.

I just bought some of the large size bearings and was wondering how people are securing them into position (main_leg_body_connector to the leg_boddy_bearling_connector).

Hey Guys

Does anyone have the link they used to buy the disk metal server horns for steering (Some Round Metal Servo Arm 25T Disc Horns.)

Hello,

I'm in the process of assembling the arm: when it comes to the grip rotator, how did you manage to install the servo? The print came out perfect but the servo doesn't slide in since the protruding rubber part where the power+pwm cable comes out leaves no space to insert the first part of the servo diagonally and then slide it in. Did you cut away some part somewhere?

Thank you

Hello.
I did not understand how this part is mounted inside the bearing? What keeps her from falling out?
Could you clarify this issue?

Hello,

I'm proceeding with all prints, and when it comes to the body I wonder what's the most efficient support type to use when slicing stl files: I'm using Cura and I usually use the default line with 10% spacing. Any hint here/what have you used?

Thank you

I'm in the process of writing the control software.
This issue is mostly to share what I'm doing and to collect hints/other views on this topic.

Since my version of this rover is based on a Raspberry Zero WH, for development speed reasons I chose to use Java. I know that performance-wise and memory/CPU-wise it sucks, but there's a ton of ready-made libraries and I don't want to reinvent the wheel.
Namely, what I'm using is:

https://pi4j.com/ - for IMU, ADC, PWM controller, etc, it has lots of libraries ready to use
https://www.eclipse.org/paho/ - MQTT communication
https://eclipse-ee4j.github.io/jersey/ - REST API

I will eventually use WiFI and LoRa for the radio/control part, and all telemetry will be sent by the rover through MQTT. MQTT will also be used for interactive control.

Pre-programmed/batch control will be handled through a set of REST APIs that the code running on the rover will provide.

First off thanks for all the hard work you have put into this project. I am interested in building this, but I am having issues sourcing a 25mm x 56mm brushless dc motor. I would like to know which ones you choose to go with.

Hi, I checked out the last version for the CAD file but I can only find the arm_holder component in there .. Is there a seperate location for the arm?

Thank you so much for this design!

Hello,

what's the best way to print the steering ball bearing? (see image) all in one print? body by body? I'm thinking to give it a try with 0.12 layer thickness and 30% infill. Did you print it or buy a ready-made one?

Thank you

Hey @jakkra does your design have enough tolerance in the CAD model for direct printing or would I need to account for shrinkage in my slicer?

What tubes are used for suspension? I measured the diameters, 25x22.6 (external / internal). but I did not find such in stores.

Hello, thank you for sharing this very interesting project: far as I can see the rocker bogie tubing is not printed but looks like standard pvc tubing: what thickness did you select?
Thank you

Hello, I recently found a next-generation mission control framework for visualization of data on desktop and mobile devices developed by NASA. This is the link https://nasa.github.io/openmct/

Hey Guys

When connecting the 2 body halves there seems to only be connectors at the top. How are others connecting the body halves together at the bottom to stop them coming apart?

Hey, just wondering if there are any pre generated STL files available or if everyone is just creating their own from the CAD?

Hello, could you share the electronics schematics?
I’m building the electronics based on a raspberry zero and that would come handy.

Thanks!

I have a Linux computer, so I have not Fusion 360. Can I have the STL files please ?
