They were from the 70’s and were plastic with rubber grip trax
{battery operated}

they could run around on their own or on a very elaborate “Suspended track” that consisted of loops and turns in mid-air….

They were extremely detailed and very colorful – with colored lights that would blink in elaborate patterns on their torso or head and their arms had clamps {each one was different in detail and consisted of “good guys and bad guys” }

One of the most elaborate was a large scale “master” robot that had another robot {detachable} that was its “brain”…
this smaller robot could also be bought seperately and was just as detailed {and moved on its own}

the track was also sold seperately and you could add- on
with different pieces of track and make your own tracks

I believe they could make sounds too {maybe, maybe not}
