Alterative hardware

[James-Canova]

I'm trying to buy the parts to make my own JetBot from the hardware list on jetbot.org.

The links to the following parts do not work:
1)Caster ball
2)Battery
3)Camera lens attachment
4)Adhesive pads

Can someone provide details of these parts so that I can search the Internet for alternative sources?

Thank you in advance.

I've been able to answer my own questions. Here are the answers...

1. Caster Ball
   https://www.amazon.ca/dp/B07TKH7QSJ/ref=cm_sw_r_apan_glt_i_8P10SP1FCFF2M758CX4H

2)Battery

But, the output ports are too close together to to use two use two 90 deg connectors (see photo) and here are the USB cables required:

3)Camera lens attachment. I'm not going to use this. The camera mount on the JetBot faces downwards which is good for tracking a line, however, I want to to object following and avoidance so I had a modified mount made, see attached photo. If you want the stl file then email me: jscanova@gmail. com. Unfortunately, however, I made one small mistake and must get it corrected.

4)Adhesive pads. These are for holding the battery in place. I could not find any that would stick to the battery so I wrapped a couple of elastics around the batter and that works fine-they stop the battery from slipping out of place. See attached photo.

Other:

The 3D parts were made with a process called powder bed fusion, selective layer sintering. The material was Nylon PA 12. It all worked out great.

Excluding the Jetson Nano 4GB B01, the total cost was $450CAD ($355US).

I'm just finishing a YOLOv4 project on my other Jetson Nano so won't get around to start loading software until next month (mid March 2022)
