HERO 1 ETW-18 Project
HERO 1 ETW-18 Project
Special Thanks up front to:
Jim Butler for passing HERO into my possession
John for keeping my hope alive the first few days - http://www.hero-1.com/
Larry Thompson at MobileEd for all the HERO 1 documents - http://www.mobileedproductions.com/
Robert Doerr for convincing me that I could work with what I had - http://www.robotswanted.com/
The Hero was a high water mark in home educational robotics. It was
a real robot that was designed to teach.
- Hero 1.3
- Serial Interface
- Max RAM (64K?)
- Demo ROM
- Replaced minor, commonly worn-out things
- Got board from RobotsWanted.com
- Put new foam around sonar sensors
- Arm not good, cracked
- Remote control receiver
- Hero 1.0
- Hero 1.0 "Scrappy"
- Hero 1.0
Additionally: 2 teaching pendants, 1 charger, and 2 remotes
(one not built).
There are a couple of demonstrations in the works using the Hero robot, intended
for students, to show them some of the things home robots are capable of,
to give them some idea what the future might hold, and to get them excited
The goal is to build an equivalent of the Hero using modern components. The
step after that will be to add new technology to it, to bring it up to date,
trick it out, but to keep the instructional purpose and the original flavor.
Using modern components, Hero could be duplicated at about a 6" height.
That might be interesting.
- ??-??-1984 Last known operation of HERO prior to 2002.
- Update: 03-01-2002
- Received excellently packed HERO 1 ETW-18 unit with Teaching Pendant
and limited documents.
- Update: 03-09-2002
- I had to do a little work on Hero's inside:
1. Head plate bent at the forward right edge - Fixed
2. A few other bent structural elements - Fixed
4. Grommets cracked and crumbled - Replaced
3. Battery leads corroded through - Batteries Replaced
Powered up Hero and ... nothing but "000" flashing every 11 seconds :(
4. Found nasty scratch on the inside back of the "Arm controller" board - Checked and functional.
5. Removed, checked, and cleaned each circuit board one by one - Completed
Applied power with minimal components ( Head circuits, Main power
board, PC board )
Display lit up with "HEro 1.0" :)
Turned off power, installed speech board, applied power again:
Display lit up with "HEro 1.0" and speakers produce that good old
Put all of the pieces back in place.
I have tested Hero with the manual remote. With the exception of
forward and reverse, every motor function is working (this includes the
head and arm).
So, as of March 9 2002 Hero is "alive" again with only a few
issues to address.
- Update: 03-21-2002
- Finished check of sensors and built in functions. All sensors
- Update: 03-22-2002
- Received documentation and schematics for HERO 1 from MobileEd.
- Update: 03-23-2002
- Turns out that the "Main Drive" problem was an ID10T error. After
I stripped HERO down for a thorough cleaning, I was off by one pin when
I reconnected P310. Once I had the manuals, I was able to do a continuity
test from the "Main Drive" to the "CPU Board". I felt pretty dumb after
I visually confirmed that the connector was off by one pin.
- Fixed broken screw mount in rear left of head cover.
- Update: 04-02-2002
- Picked up shipment of 8 new batteries with proper connectors.:)
- Update: 04-06-2002
- Swapped Head and Steering motors (and back again), checked steering
gear box, and finally found bad connection problem with the main power board.
- Fixed connection problem. HERO is now 100% functional.:)
- Update: 04-07-2002
- HERO makes 2002 film debut in 2 minute short film.
- Update: 04-11-2002
- Recorded voice elements for short film.
- Update: 04-12-2002
- Sucessfully tested micro-cassette recorder as "new" tape drive for HERO.
- Update: 04-14-2002
- Purchased two foam filled aluminum cases; one holding the arm and
one for the Teaching pendant, extra batteries, rechargers, and tools.
