Self-transforming Grimlock robot joins Optimus Prime, showcases complex engineering but high price tag

Robosen has created a new $1,700 Grimlock robot that transforms itself and interacts through voice commands.
Grimlock can walk in both robot and T.rex mode and balances using sensors and servos.
It features accessories like a rocket launcher and sword, along with the original voice actor and 150 voice lines.
The transforming robots showcase impressive engineering but also have limitations and high costs.
This follows the previous self-transforming Optimus Prime robot that retailed for $1,500.
