Purchase of ServoCity Radio Control Kit 20V 3203-0020-0201

Hello,

As part of a school project, I would need some advice from you.

I am in my final year of training as a mechanical draughtsman. We are working on a project with four people at school. We have decided to make a simplified scale model of the Perseverance rover.

We will be doing all the mechanical design with 3D-printed and machined parts. However, we do not have any electricians, so our knowledge of electronics is limited.

Initially, I calculated the torque and rotational speed required for our rover. It will weigh around 20-25 kg and we would like it to travel at 1-3 km/h. The aim is not for it to go fast, but to be able to overcome obstacles such as rocks on rough forest paths.

I found the ServoCity Saturn Planetary Motor Series 5303 with Encoder (188:1, 100 rpm) 5303-2402-0188, which seemed really well suited to our needs. I then found on the Servocity website that there was a kit that included all the equipment needed to control these motors. We would put four motors on the four outer wheels of the rover. It will actually have six wheels, but the two in the middle will not be motorised.

I wanted to know what you thought of my choices and whether you thought that what I had chosen was more or less suitable, at least in terms of the electronics for this rover. If I order this kit with the motors, I wanted to know if it would be possible to ‘reserve’ one of these 3203-0020-0201 kits for me, as you do not have any in stock but will be receiving more in a month. As for the motors, I wanted to ask you when I could expect to receive them.

Please let me know if you have any questions about my request, and thank you in advance for taking the time to review it.

I look forward to hearing from you. Best regards and have a great day.

Hello @Lulu_2006_Drawner and welcome to our forum!

Sounds like you have an interesting project here!

To me, your choice of the ServoCity Saturn Planetary Motor Series 5303 with Encoder (188:1, 100 rpm) 5303-2402-0188 and the 20V Radio Control Bundle (3203-0020-0201) appears to be well-suited for your project, especially considering your mechanical focus and limited electronics experience.

Your components are well-matched and robust enough for your 20-25 kg rover to travel at 1-3 km/h over rough terrain. The electronics kit is especially a smart choice for a mechanically focused team.

Maybe you could share some photos of your project?

Thank you.

Hello,

Thank you very much for your reply.

I don’t really have any photos because we don’t have any physical parts yet. We are going to start the mechanical design now that we are sure we have the right electronic components.

However, I can give you the name of a youtube channel that shows a tutorial on how to do a project very similar to ours.

It’s the How To Mechatronics channel

But I have an important question. It concerns recharging the battery using the charger. It’s a US plug. But as I live in Switzerland, is it enough to buy a US-Swiss adapter? I think I can do that, since the charger accepts 100 to 260V and a frequency of 50 to 60Hz. And in Switzerland, it’s 230V and 50Hz.

Hi @Lulu_2006_Drawner ,

Yes, if the charger accepts 100-260VAC as input you can use it in Switzerland.

You just need US to Swiss AC plug adapter as you already mentioned.
