Adept/Omron is the biggest pile of xxxx i´ve ever seen.
Manipulator is more or less OK, except the fact that after the robot took a hit in 10% speed and second axis reduction gear was gone (scara robot). Also spare parts are extremely pricy, whole robot was f.e. 1000 euro and 1 gear reduction was around 900 euro as spare part. Thieves.
Slow communication(ethernet ip), newer robots (they announced them 6 months ago) are fine they have ethercat now, no predefined external signals (start, stop, etc) - for education no problem perhaps.
Software is extremely buggy ACE 3.8.x, ACE 4.3.x, and nothing is better.
