Please help me decide parts formy robot project

Hi All,

I want to build a bot for oudoor that can handle bad terrain for fun, and whack aload of cameras on it.

Im a coder, and have very limited knowledge of putting a bot together.

Requirements I want:

Very accurate pose estimation. I was thinkig about doubling up on a few things and avergaing the readings. gps, imu ect

To be able to commicate with the bot at maybe 50-100 meters

Handle rough terrain.

I am worried that im missing some stuff? maybe ardino bits or wires ect, boards, ports? I would really appreciate a pro telling me what im missing.

Massive thanks in advance.

This is my shopping list:

WIFI

TIME-OF-FLIGHT 2

LIDAR 1

IMU 2

GPS 1

GPS (2) 1

raspbaery pi 1

360 camera 1

depth camera 1

AI cameras 1

wild thumper 1

Hello @jtm812 and welcome to the RobotShop community!

Awesome! The Dagu Wild Thumper is a great rover for outdoors! Good choice :grinning:
Just keep in mind that that is just a chassis kit with motors so you’ll also need a Motor Controller and also a battery


and whack aload of cameras on it.

A great option could be using just one good camera with a Pan & Tilt kit.

I think one GPS should be enough but you could also check other options for precise outdoor Localization such as GNSS modules or RTK GPS devices.

To be able to commicate with the bot at maybe 50-100 meters

Do you want to control it remotely or do you want it to be autonomous? Or maybe both and switch the mode? If you want the first option then you’ll could use a [transmitter/receiver](https://Wireless RC / PWM Servo Controllers), if you want the second option you’ll need a Microcontroller or maybe a Single Board Computer and maybe some sensors.

The thread type on the Dagu rover wheels is perfect for outdoor use

I suggest re-checking your shopping list to see if all the parts you chose are compatible and if they are really necessary. For example, the first thing you linked is a WiFi Module used to add wifi to Makeblock boards like Orion or Arduino boards, not to the Raspberry Pi (which already has Wifi).

The second product is meant to be used with AUVs and a PIX 3DR Ground Station so it won’t work for your application. A better option would be a receiver that you connect the motor controller and a transmitter that you use for controlling it remotely.

A LIDAR is a great sensor for SLAM (simultaneous localization and mapping), but if you are also planning to add AI cameras I don’t think it is really necessary. A great option would be using a stereo AI camera like this one:


Which can be used for depth perception and 3D localization.

That is a lot of information so I think I will stop here haha, but let me know if you have other questions :grinning:
