Benny's Space Mech

[CheungsLegoCreation]

Hi all,

Long time no post ;) And here's my latest powered up based mech, utilising 2 technic hubs and 8 motors. 3 motors are used for walking and turning, 1 motor is for raising the arms and moving the antenna, the rest of the motors are for arms movement. 

Compare to my previous bot, this bot features wider feet, allowing the mech to walk with less body tilt. I hope you will enjoy watching the video. If you have any question about it ask away :)

Take care and happy building.

Cool mech!

What do you use to control it and how complicated is that setup?

[CheungsLegoCreation]

Thanks Heppu.

Basically I used the Powered Up App to setup the control. The legs and shoulder movements are all connected to one hub and the arms are done using another hub. Buttons are used for controlling movements (front, back, left and right), vertical sliders are used to raising the shoulder and arms, buttons are used for opening and closing the hands.

I mainly used the mindstorms hub for prototyping and then convert the design into one using the control+ hubs. Obviously the main disadvantage of this approach is I need to factor in the weight of the batteries and sometimes it would require redesign (in this case I need to increase the width of the feet to make it tilt less as it walks otherwise it could flip sideway).

I am working on a mech that hopefully will use a single hub (4 ports) and yet will perform pretty much similar actions (to a certain degee) but it will take at least a few weeks though.

Programming using Pybrick could be easier (which I have not tried) and I am not sure if I can connect to 2 hubs at the same time using the web programming interface. I guess I will just have to try and see what happens.

Happy building!
