LiDAR Lite and sensors mounting on a robot car

[changks888]

Dear all,

I am trying to buy some sensors to mount on a robot car moving on a golf court.

Sensors/devices include: LiDAR Lite 2, voltage regulator, Line Laser Diode, GPS, RTC, Gyro and Accelerometer, SD card datalogger.

Hope you can provide the answer/suggestion.

My questions:

1. Does Standoff Mounting Kit M3 (i.e, RB-Dfr-273) fit into Actobotics Aluminum Channel (i.e., RB-Sct-355)? What is the right parts to mount sensors/device on a robot car from Robot Shop?

We like to mount LiDAR Lite 2 and sensor head down above the land surface 10 cm.

2. What is recommended 4WD robot car for this task? The loading weight is less than 2 kg. and it will be moving on a golf court.

The arduino board can handle all the sensors mentioned above and gets (read & log to Arduino) measurements when robot car moves.

3. Do you suggest add a voltage regulator for the LiDAR Lite DC power input? Which one do you guys prefer?

4. Do you have similar Line Laser Diode product like this: adafruit.com/products/1057

We intend to see the moving direction and LiDAR scanning pathway. Any suggestions?
5. Gyro and Accelerometer breakout for Arduino board on a robot car?

6. 5V Power rechargeable battery pack to power entire system (i.e., motor, arduino, lidar, laser, GPS, Gyro, Accelerometer, SD card data logger)?
   Thanks a lot.

Hi,

@changks888

1. Does Standoff Mounting Kit M3 (i.e, RB-Dfr-273) fit into Actobotics Aluminum Channel (i.e., RB-Sct-355)?

The M3 width is smaller than the 6-32 used in the Actobotics Aluminum Channel (and all their other parts, too), but it would still work. Please note that since the M3 screws are smaller, they would be a bit loose.
You can find many parts that match this aluminum channel in this section: robotshop.com/en/actobotics-parts.html
You can find the screws by searching 6-32, like this: robotshop.com/en/catalogsear … unt&q=6-32

2. What is recommended 4WD robot car for this task? The loading weight is less than 2 kg. and it will be moving on a golf court.

The Lynxmotion Aluminum A4WD1 Rover Kit [RB-Lyn-63] may fit your purpose. It is able to carry up to 5 lbs (including batteries. ~2.26 kg). It uses 12 V DC motors. You can view it here: robotshop.com/en/4wd1-robot- … m-kit.html
This is the recommended motor driver for this rover kit: robotshop.com/en/sabertooth- … river.html

3. Do you suggest add a voltage regulator for the LiDAR Lite DC power input? Which one do you guys prefer?

The LIDAR-Lite can be powered directly from the regulated 5 V DC from the Arduino’s on-board regulator. If you are concerned about signal noise, you can always add a capacitor (~100 uF) between the VCC and GND lines of the sensor.

4. Do you have similar Line Laser Diode product like this: adafruit.com/products/1057 We intend to see the moving direction and LiDAR scanning pathway. Any suggestions?

We do not carry this product at this moment. You can see an alternative product with integrated controller here: robotshop.com/en/ttl-laser-red-diode.html

You can find gyro boards here: robotshop.com/en/catalogsear … t&dir=desc
You can find accelerometer boards here: robotshop.com/en/catalogsear … t&dir=desc

Depending on your chassis and motors / motor controller, you may very well need two batteries. In our Lynxmotion rover kits, we usually have either a 6V or 12V NiMH battery pack for the motors / motor controller and another 6V NiMH battery pack for the Arduino-compatible board.
You can browse the NiMH battery packs here: robotshop.com/en/nickel-meta … packs.html
