manufacturing efforts
Jan 2023
CE certification plan complete
Final setup of manufacturing line
Handoff to operations to
execute on manufacturing
Final update and release of all
production drawings (Rev B)
December
Software validated
1st MZ101 pre-production unit assembled
and debugged
Assembly documentation for
manufacturing floor builds
Draft CE assessment complete
November
GUI complete
Pre-orders?
MZ101-P2A working unit?
Only necessary if there is a major learning from P1 build.
FEA and testing have shown no major issues, even at 30 degrees we still have almost a 5x factor of safety as a foreseeable misuse case.
Executable marketing plan
October
Show unit / marketing requirements?
Start system software validation
and debug for production
Draft risk assessment complete
Risk assessment complete
GUI requirements locked down
MZ101-P2A design release?
(Parts or machine)
Inhouse testing with real masons
Production software functions
locked down
Customer R&D design review
application meeting
Production design release for 1st
manufacturing test run (Rev A)
September
Working MZ101-P1B production
intent prototype
- As a result of the motor issue, further development was done on P1 in parallel to further de risk the need for a P2 build further.
GUI layout requirements

4/28:
- pending arrival of InMotion parts for testing on MZ2
August
MZ101 official production forecast
for vendors to protect supply chain
4/15
- Sales team requested a rough spec sheet and rough costing for pricing ROM to gauge volume market by.
4/28
- Had to push effort from April to May because fabrication parts not back from quote yet. Working to get rest of critical components in BOM updated in parallel.
Marketing strategy outline
Start ordering long lead electronics
to protect production supply
Executable manufacturing plan
for setup in new building
Work with vendors to get forecast
and lead time understood for long
lead electronics.
Setup electric gripper testing
on ML150 for application,
debug, and robustness
- testing completed and went well. Servos were programed to have self held safety limits independent of controller board.
- Johnathan is having issue with production intent board and cooked servo and/or board so had to take parts from working prototype for him to continue.
- Ordered more servos so we have spares, will also order a few metal gear servos as a backup in case we find plastic servos not to last.
Electrical documentation complete
with all critical components for
manufacturing MZ101
Perform second full FEA of production
intent design release
July
Validate critical functions
of wireless handle w/ gripper
Perform first full FEA of production
intent design release
Review FEA Results
June
Evaluate use cases of all current
ML150 accessories
Primary function testing
and debug
High level manufacturing strategy
outline for new building setup
Resolve motor & gearbox
supply chain issues
May
Benchmark MZ101 cost
- Waiting on quotes from vendors, drawings released mid April.
- Need quotes back so final design changes can be made to weldments for fabrication for prototype.
RT mobility application
study complete for JLG mobility
base requirements
Build MZ100-2 for testing critical
controls design changes
- Must push to till next month (May) because of vendors not providing parts. May come first week in May but working to verify since engineering is believed to be done on their end for production of parts to CR.
Release MZ101-P1 drawings for
fabrication
MZ101 application testing plan
MZ101 robustness testing plan
April
Dave L drastic hours cutback?
- Jake full time to resolve
- Minor handle tweaks
- Detailing still needs to be done
- Cover started but still needs a bit of design work
- Parts for 5 old handle weldments should be in soon
- No other tasks lingering for Dave L
Interior mobility application
study complete for JLG mobility
base requirements
Resolve battery and power
issues in cold weather
4/28
- Switching to inventus battery will simplify design and allow faster warm up with internal heating cells while charging / discharging.
