I'm pretty sure the show was out in the 80's or maybe even very early 90's but it could also have been an animated movie (If so would most likely have been a straight to VHS effort)...
Now all I have is a very vague/blurred memory of it so I will try and describe what I recall as best I can:
- I remember there were multiple different coloured robots, one was orange, one was green, pink, blue etc
- Each robot was unique with its own appearance and abilities
- I'm pretty sure one moved around on one wheel while it could shoot out its hands/claws to reach further
- I think one had wheels on the end of its arms which it could fold down and form into a sort of vehicle and go really fast
- I specifically remember a scene where they were trapped in a brown cave looking for a way out but again this is a very old vague memory
I have been searching through the internet with no results at all. It's definitely not Transformers, Gobots, Gundam, Mask, Voltron, Mighty Orbots.
Again this could have been a short animated film but I am leaning more towards a series.
After doing some further research, the character "Grounder" from an old Sonic the Hedgehog series bares a resemblance of what the style of robots looked like but all unique in their own way - Different colours and builds.
Also another show "Super robot monkey team hyperforce go" (SRMTHG) shows the "Monkey/robots" with different accessories for hands - One has drills, another magnets and another has spinning blades... These really triggered the memory for me.
Again the show is a lot older than both of these if my memory serves me correctly.
