Mattel RC babies — Jennie Gymnast, Baby Rollerblade, and Baby Walk 'n' Roll
Mattel RC baby dolls
Three separate early-1990s Mattel RC babies in one workshop batch: Jennie the gymnast (handset and switch path), the roller-skate baby (stripped gear and leg alignment), and the baby walker (gearbox, contacts, board, and signal path) — each needed deep electronics and mechanical work.

The repair
Jennie Gymnast (gymnastic Jenny): we replaced the controller switch, removed a faulty connector and damaged cable section, and brought the handset path back to reliable continuity. Baby Rollerblade (roller-skate baby): a broken gear in the drive was replaced, leg position was readjusted so the skating motion tracks straight, and the mechanism was re-timed after reassembly. Baby Walk 'n' Roll: this one was the longest troubleshoot — a broken gear inside the walker gearbox, tired battery contacts, circuit board faults, and a damaged signal track between board and motors. We replaced the gear, renewed contacts, repaired the board, rebuilt the signal path, and lubricated the drivetrain so the walker responds smoothly to the joystick again.
