| | | I had to buy this set just to see. Total disappointment :( Nice idea, dreadful implementation. The motor/battery box clearly tries to record the rotation of each of two wheels in "record" mode, and I think it actually manages to do that part ok. The (...)

| | | | | (...) I couldn't agree more. I was ecstatic when I saw this at the local TRU, so I bought one. Probably bought the FIRST one. The "programmable" brick did NOTHING like I had recorded it to do - time after time. Went too fast, didn't rotate to the (...) (21 years ago, 10-Nov-03, to lugnet.robotics)

| | | | | I agree too that the record and play unit is not up to the task, even if models look fine and colorful - this is the case of all inventor sets, the shapes and color schemes are really attractive. My expectations were not too high for the control (...) (21 years ago, 11-Nov-03, to lugnet.robotics)

| | | | To add some further information, I popped the unit open last night and observed that, as I had hoped, mechanically the unit should be capable of operating correctly. Each motor channel has a mouse style slotted wheel and sensor, so the firmware (...) (21 years ago, 12-Nov-03, to lugnet.robotics)

| | | | | | Motor Power —Gahlord Dewald
|
| | | | | Hi all, I'm a lurker/newbie. I'm wanting to build a controlled platform that can move and rotate (sort of like a turtle using LOGO). I'd like this platform to carry my E-10 camera (weighs 37 oz./1048 grams). Can anything using the RCX/mindstorms (...) (21 years ago, 12-Nov-03, to lugnet.robotics)

Beat: (URL) I don't know for sure, but there's gotta be 50 pounds of plastic in (...) (21 years ago, 12-Nov-03, to lugnet.robotics)

It all depends on your gearing and set-up, but I have a 10-pound model that rolls along easily powered (...) (21 years ago, 13-Nov-03, to lugnet.robotics)

| | | | | | (...) I've built a rudimentary motion control system with Mindstorms, but as the motors are not really steppers, I found I had some precision issues. Pulsing and timing never really got close enough for a repeatable move. You can use rotation (...) (21 years ago, 12-Nov-03, to lugnet.robotics)

Traction was the limiting factor, with tyres slipping - the (...) (21 years ago, 14-Nov-03, to lugnet.robotics)
