Behold! My ERX-01 Robotic Crawler. Please let me know if you have an questions or if I need to modify a part!

UPDATE:

The Version shown in the thumbnail now uses the rover body kit. You can download that here. I like it a lot more than the original body.

*Added rear brace and changed the sprocket mount to better hold the track assembly together.

*Fixed Driver Tray

*"I forgot to add the power switch I used. I chose this one because its a 3 way which allowed me to charge battery in what I called "Charge Mode". https://www.amazon.com/dp/B08YMZJ9GL?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2

This is a differential drive machine that you can operate in a number of ways. This version would be more suitable as an RC vehicle. The body uses easy to swap panels so you can print your own pieces that fit whatever type of sensors you prefer if you are doing an automous robot.

Parts specific to this design: 12V worm gear DC Motor (Pic included for size. A few variations should fit)

12V LifePO4 Battery (A Lipo would be much lighter and save weight but I dont mess with those anymore)

DROK DC Motor Driver (Fits on mount but there'sspace for different kinds) https://www.amazon.com/dp/B06XGD5SCB?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_5

R8-2RS Bearing (For track assembly sides) https://www.amazon.com/dp/B08CN5TJLS?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1

M3 Screws (TRACKS MUST USE 30MM FOR CONNECTING)

M4 Screws (20mm)

1/2 Bolts (2x 1/2-13 x 5) https://www.amazon.com/dp/B00L1L9VK2?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1

1/2 Nuts https://www.amazon.com/dp/B07DGPHMJ1?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1

Motor Flange 6mm https://www.amazon.com/dp/B0B63P5VVX?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2

IF DOING AN AUTONOMOUS ROBOT:

There are inner track assembly pieces labled "ENCODER". These are the encoders those are designed for. Other wise use the WITHOUT ENCODER inner assembly. https://www.amazon.com/dp/B085ZLCYS1?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1
